1 Integrated Waste Management Consulting LLC Overs Sorting Study October 2012
Objective The objective of this study was to analyze a random sampling of ldquooversrdquo1 at selected composting facilities to determine if compostable plastics account for more than 10 percent of the overs and to characterize the type and amount of remaining plastic residue This work will help to quantify the composition of overs which are ordinary plastics and which are ldquocompostable plasticsrdquo Introduction As more and more food scraps diversion programs come on line compostable plastics are seen as helping to facilitate increased participation and increased capture rate of these programs The city of Portland and similar jurisdictions implementing source-separated food scraps collection programs must make choices and policy decisions as to what types of materials are allowable and which are not Most food scraps collection programs due to the desire to maximize diversion from landfills tend to be fairly inclusive in terms of materials accepted For example while we broadly categorize these programs as ldquofood scrapsrdquo collection programs most of these programs also allow food-soiled paper and food related paper products (eg pizza boxes) in addition to food scraps In addition many of these emerging programs allow or encourage ldquocompostablerdquo food service ware (ie plates cups forks etc) or bags as part of the program There is emerging information from Europe Canada and Washington state2 that programs that allow compostable bags (primarily as in-home bin liners) can increase participation in food scraps collection programs In addition many commercial food scraps programs allow and encourage ldquowet-strengthrdquo cardboard that is commonly used to package produce and similar materials as part of the ldquofood scrapsrdquo stream Study Methodology The scope of this project included identifying two large commercial compost facilities receiving food scraps collected from the city of Portland Oregon The facilities were interviewed to establish baseline composting conditions (ie composting technology retention time separation methods etc) Random samples of ldquooversrdquo from the screening process were selected and sorted using manual sorting techniques Samples were collected from stockpiles identified by the facility operators (See Figure 1) Individual samples were gathered in 5-gallon buckets Each 5-gallon subsample was weighed documented and then hand-sorted (See Figure 2) Sorters selected any and all contaminants encountered in the overs and classified each item into one of three possible categories
1 Most commercial compost facilities screen the finished compost product prior to sale in order to create a homogenous product Some screens can create two products some three The oversize particles (those not passing through the screens) are commonly referred to as ldquooversrdquo

1) Film Plastic which included any thin extruded plastic such as bags cup liners gloves wrappers etc (Please see Figures 3 amp 4)
2) Rigid Plastic This category included essentially all non-film plastic including hard plastic
cutlery plates etc 3) Other The other category included any non-plastic contaminants encountered in the overs
This included wet-strength cardboard glass wire rocks and other non-plastic items Interestingly though it was not documented for this study the ldquootherrdquo category included a significant amount of wet-strength cardboard (the type of cardboard that is commonly used to package some produce for grocery stores) This material would appear to be a challenge to fully breakdown during an abbreviated composting process Little effort was made to distinguish between the types of plastic encountered during the sorting process because visually distinguishing one type of plastic from another can be very difficult after the rigors of the composting process At the end of each subsample the recovered commodities were photographed weighed and bagged for shipment to a third-party laboratory (Advanced Materials Center ndash AMC) in Illinois for further laboratory analysis and identification (Please see Figures 5 amp 6) Five-gallon buckets were chosen as the sorting volume because they are a convenient and manageable size for this type of project Also there are roughly 40 five-gallon buckets in a cubic yard thus using five-gallon buckets allows for easy bulk density conversion However the relatively low bulk density of say film plastic does not really lend itself to weight-to-weight comparisons Thus the weight of the plastic itself is not the best way to represent the importance of the presence of this material in the overs Results Both of the selected compost sites use covered aerated static pile composting systems Both sites screen their finished compost after the composting process though one sitersquos screen used a one-pass type screen (which creates ldquooversrdquo and ldquofinesrdquo) and the other used a screen which made three products ndash overs ldquomiddlesrdquo and fines Plastics and other contaminants were encountered in all overs products and also in the ldquomiddlesrdquo product The results of the field sorting are summarized in Table 1 below The field sorting showed that the weight of plastics relative to the weight of the overs was not significant Also the weight of ldquootherrdquo contaminants was greater than the weight of all plastics removed Because of the two fractions at the first facility two distinct sorts were done ndash one of the overs one of the middle fraction However it is not valid to say that more or less contaminants were encountered at this facility but rather that more material was sorted thus a larger weight of contaminants was removed

13 Integrated Waste Management Consulting LLC Overs Sorting Study October 2012
Conclusions Based on IWMCrsquos experience the amount of all plastics removed from the overs at both facilities was comparable and fairly typical of composting facilities handling food scraps from relatively new collection programs The amounts of compostable plastics recovered ranged from 2 to 8 However it is clear based on AMCrsquos analysis that the composition of the plastic was overwhelmingly ldquoconventionalrdquo plastics (polyethylene polypropylene etc) While a small amount of compostable plastic was recovered in the overs it appears to be less than 4 of the total material analyzed by AMC While this could indicate that truly compostable plastics are breaking down significantly during the composting process at these two sites the study did not have any information on the ldquoupstreamrdquo volume of compostable plastics So it is impossible to make this conclusion The most prevalent plastics in the overs were film plastic consisting of two-thirds of the total sampled in the field Subsequent lab analysis showed these to be overwhelmingly made from non-biodegradable plastic (Polyethylene and Polypropylene) Less than one percent of the total samples of hard plastic were cutlery Approximately half of this consisted of starch and polypropylene and would not be expected to biodegrade or disintegrate The other half was identified as potentially compostable The study did not have enough data to determine why the cutlery might not be breaking down though the fact that large amounts of wet-strength cardboard was also recovered suggests the compost retention time might not be sufficient to degrade these types of materials Recommendations The study found that the overwhelming majority of the plastics in the overs were non-degradable plastics As such limiting the distribution and promotion of truly compostable items will do little to reduce the total plastic in the overs stream Portland and its surrounding cities with food scraps collection programs need to address the prevalence of non-degradable plastic in the food scraps stream This can best be done through a targeted outreach program Outreach should be targeted at all sectors of the collection stream including generators vendors and collectors

Determining the Amount of Plastic and Compostable Plastic in Compost ldquoOversrdquo
1 Integrated Waste Management Consulting LLC Overs Sorting Study October 2012
Objective The objective of this study was to analyze a random sampling of ldquooversrdquo1 at selected composting facilities to determine if compostable plastics account for more than 10 percent of the overs and to characterize the type and amount of remaining plastic residue This work will help to quantify the composition of overs which are ordinary plastics and which are ldquocompostable plasticsrdquo Introduction As more and more food scraps diversion programs come on line compostable plastics are seen as helping to facilitate increased participation and increased capture rate of these programs The city of Portland and similar jurisdictions implementing source-separated food scraps collection programs must make choices and policy decisions as to what types of materials are allowable and which are not Most food scraps collection programs due to the desire to maximize diversion from landfills tend to be fairly inclusive in terms of materials accepted For example while we broadly categorize these programs as ldquofood scrapsrdquo collection programs most of these programs also allow food-soiled paper and food related paper products (eg pizza boxes) in addition to food scraps In addition many of these emerging programs allow or encourage ldquocompostablerdquo food service ware (ie plates cups forks etc) or bags as part of the program There is emerging information from Europe Canada and Washington state2 that programs that allow compostable bags (primarily as in-home bin liners) can increase participation in food scraps collection programs In addition many commercial food scraps programs allow and encourage ldquowet-strengthrdquo cardboard that is commonly used to package produce and similar materials as part of the ldquofood scrapsrdquo stream Study Methodology The scope of this project included identifying two large commercial compost facilities receiving food scraps collected from the city of Portland Oregon The facilities were interviewed to establish baseline composting conditions (ie composting technology retention time separation methods etc) Random samples of ldquooversrdquo from the screening process were selected and sorted using manual sorting techniques Samples were collected from stockpiles identified by the facility operators (See Figure 1) Individual samples were gathered in 5-gallon buckets Each 5-gallon subsample was weighed documented and then hand-sorted (See Figure 2) Sorters selected any and all contaminants encountered in the overs and classified each item into one of three possible categories
1 Most commercial compost facilities screen the finished compost product prior to sale in order to create a homogenous product Some screens can create two products some three The oversize particles (those not passing through the screens) are commonly referred to as ldquooversrdquo

1) Film Plastic which included any thin extruded plastic such as bags cup liners gloves wrappers etc (Please see Figures 3 amp 4)
2) Rigid Plastic This category included essentially all non-film plastic including hard plastic
cutlery plates etc 3) Other The other category included any non-plastic contaminants encountered in the overs
This included wet-strength cardboard glass wire rocks and other non-plastic items Interestingly though it was not documented for this study the ldquootherrdquo category included a significant amount of wet-strength cardboard (the type of cardboard that is commonly used to package some produce for grocery stores) This material would appear to be a challenge to fully breakdown during an abbreviated composting process Little effort was made to distinguish between the types of plastic encountered during the sorting process because visually distinguishing one type of plastic from another can be very difficult after the rigors of the composting process At the end of each subsample the recovered commodities were photographed weighed and bagged for shipment to a third-party laboratory (Advanced Materials Center ndash AMC) in Illinois for further laboratory analysis and identification (Please see Figures 5 amp 6) Five-gallon buckets were chosen as the sorting volume because they are a convenient and manageable size for this type of project Also there are roughly 40 five-gallon buckets in a cubic yard thus using five-gallon buckets allows for easy bulk density conversion However the relatively low bulk density of say film plastic does not really lend itself to weight-to-weight comparisons Thus the weight of the plastic itself is not the best way to represent the importance of the presence of this material in the overs Results Both of the selected compost sites use covered aerated static pile composting systems Both sites screen their finished compost after the composting process though one sitersquos screen used a one-pass type screen (which creates ldquooversrdquo and ldquofinesrdquo) and the other used a screen which made three products ndash overs ldquomiddlesrdquo and fines Plastics and other contaminants were encountered in all overs products and also in the ldquomiddlesrdquo product The results of the field sorting are summarized in Table 1 below The field sorting showed that the weight of plastics relative to the weight of the overs was not significant Also the weight of ldquootherrdquo contaminants was greater than the weight of all plastics removed Because of the two fractions at the first facility two distinct sorts were done ndash one of the overs one of the middle fraction However it is not valid to say that more or less contaminants were encountered at this facility but rather that more material was sorted thus a larger weight of contaminants was removed

13 Integrated Waste Management Consulting LLC Overs Sorting Study October 2012
Conclusions Based on IWMCrsquos experience the amount of all plastics removed from the overs at both facilities was comparable and fairly typical of composting facilities handling food scraps from relatively new collection programs The amounts of compostable plastics recovered ranged from 2 to 8 However it is clear based on AMCrsquos analysis that the composition of the plastic was overwhelmingly ldquoconventionalrdquo plastics (polyethylene polypropylene etc) While a small amount of compostable plastic was recovered in the overs it appears to be less than 4 of the total material analyzed by AMC While this could indicate that truly compostable plastics are breaking down significantly during the composting process at these two sites the study did not have any information on the ldquoupstreamrdquo volume of compostable plastics So it is impossible to make this conclusion The most prevalent plastics in the overs were film plastic consisting of two-thirds of the total sampled in the field Subsequent lab analysis showed these to be overwhelmingly made from non-biodegradable plastic (Polyethylene and Polypropylene) Less than one percent of the total samples of hard plastic were cutlery Approximately half of this consisted of starch and polypropylene and would not be expected to biodegrade or disintegrate The other half was identified as potentially compostable The study did not have enough data to determine why the cutlery might not be breaking down though the fact that large amounts of wet-strength cardboard was also recovered suggests the compost retention time might not be sufficient to degrade these types of materials Recommendations The study found that the overwhelming majority of the plastics in the overs were non-degradable plastics As such limiting the distribution and promotion of truly compostable items will do little to reduce the total plastic in the overs stream Portland and its surrounding cities with food scraps collection programs need to address the prevalence of non-degradable plastic in the food scraps stream This can best be done through a targeted outreach program Outreach should be targeted at all sectors of the collection stream including generators vendors and collectors

Overs Sorting Study
Determining the Amount of Plastic and Compostable Plastic in Compost ldquoOversrdquo
1 Integrated Waste Management Consulting LLC Overs Sorting Study October 2012
Objective The objective of this study was to analyze a random sampling of ldquooversrdquo1 at selected composting facilities to determine if compostable plastics account for more than 10 percent of the overs and to characterize the type and amount of remaining plastic residue This work will help to quantify the composition of overs which are ordinary plastics and which are ldquocompostable plasticsrdquo Introduction As more and more food scraps diversion programs come on line compostable plastics are seen as helping to facilitate increased participation and increased capture rate of these programs The city of Portland and similar jurisdictions implementing source-separated food scraps collection programs must make choices and policy decisions as to what types of materials are allowable and which are not Most food scraps collection programs due to the desire to maximize diversion from landfills tend to be fairly inclusive in terms of materials accepted For example while we broadly categorize these programs as ldquofood scrapsrdquo collection programs most of these programs also allow food-soiled paper and food related paper products (eg pizza boxes) in addition to food scraps In addition many of these emerging programs allow or encourage ldquocompostablerdquo food service ware (ie plates cups forks etc) or bags as part of the program There is emerging information from Europe Canada and Washington state2 that programs that allow compostable bags (primarily as in-home bin liners) can increase participation in food scraps collection programs In addition many commercial food scraps programs allow and encourage ldquowet-strengthrdquo cardboard that is commonly used to package produce and similar materials as part of the ldquofood scrapsrdquo stream Study Methodology The scope of this project included identifying two large commercial compost facilities receiving food scraps collected from the city of Portland Oregon The facilities were interviewed to establish baseline composting conditions (ie composting technology retention time separation methods etc) Random samples of ldquooversrdquo from the screening process were selected and sorted using manual sorting techniques Samples were collected from stockpiles identified by the facility operators (See Figure 1) Individual samples were gathered in 5-gallon buckets Each 5-gallon subsample was weighed documented and then hand-sorted (See Figure 2) Sorters selected any and all contaminants encountered in the overs and classified each item into one of three possible categories
1 Most commercial compost facilities screen the finished compost product prior to sale in order to create a homogenous product Some screens can create two products some three The oversize particles (those not passing through the screens) are commonly referred to as ldquooversrdquo

1) Film Plastic which included any thin extruded plastic such as bags cup liners gloves wrappers etc (Please see Figures 3 amp 4)
2) Rigid Plastic This category included essentially all non-film plastic including hard plastic
cutlery plates etc 3) Other The other category included any non-plastic contaminants encountered in the overs
This included wet-strength cardboard glass wire rocks and other non-plastic items Interestingly though it was not documented for this study the ldquootherrdquo category included a significant amount of wet-strength cardboard (the type of cardboard that is commonly used to package some produce for grocery stores) This material would appear to be a challenge to fully breakdown during an abbreviated composting process Little effort was made to distinguish between the types of plastic encountered during the sorting process because visually distinguishing one type of plastic from another can be very difficult after the rigors of the composting process At the end of each subsample the recovered commodities were photographed weighed and bagged for shipment to a third-party laboratory (Advanced Materials Center ndash AMC) in Illinois for further laboratory analysis and identification (Please see Figures 5 amp 6) Five-gallon buckets were chosen as the sorting volume because they are a convenient and manageable size for this type of project Also there are roughly 40 five-gallon buckets in a cubic yard thus using five-gallon buckets allows for easy bulk density conversion However the relatively low bulk density of say film plastic does not really lend itself to weight-to-weight comparisons Thus the weight of the plastic itself is not the best way to represent the importance of the presence of this material in the overs Results Both of the selected compost sites use covered aerated static pile composting systems Both sites screen their finished compost after the composting process though one sitersquos screen used a one-pass type screen (which creates ldquooversrdquo and ldquofinesrdquo) and the other used a screen which made three products ndash overs ldquomiddlesrdquo and fines Plastics and other contaminants were encountered in all overs products and also in the ldquomiddlesrdquo product The results of the field sorting are summarized in Table 1 below The field sorting showed that the weight of plastics relative to the weight of the overs was not significant Also the weight of ldquootherrdquo contaminants was greater than the weight of all plastics removed Because of the two fractions at the first facility two distinct sorts were done ndash one of the overs one of the middle fraction However it is not valid to say that more or less contaminants were encountered at this facility but rather that more material was sorted thus a larger weight of contaminants was removed

13 Integrated Waste Management Consulting LLC Overs Sorting Study October 2012
Conclusions Based on IWMCrsquos experience the amount of all plastics removed from the overs at both facilities was comparable and fairly typical of composting facilities handling food scraps from relatively new collection programs The amounts of compostable plastics recovered ranged from 2 to 8 However it is clear based on AMCrsquos analysis that the composition of the plastic was overwhelmingly ldquoconventionalrdquo plastics (polyethylene polypropylene etc) While a small amount of compostable plastic was recovered in the overs it appears to be less than 4 of the total material analyzed by AMC While this could indicate that truly compostable plastics are breaking down significantly during the composting process at these two sites the study did not have any information on the ldquoupstreamrdquo volume of compostable plastics So it is impossible to make this conclusion The most prevalent plastics in the overs were film plastic consisting of two-thirds of the total sampled in the field Subsequent lab analysis showed these to be overwhelmingly made from non-biodegradable plastic (Polyethylene and Polypropylene) Less than one percent of the total samples of hard plastic were cutlery Approximately half of this consisted of starch and polypropylene and would not be expected to biodegrade or disintegrate The other half was identified as potentially compostable The study did not have enough data to determine why the cutlery might not be breaking down though the fact that large amounts of wet-strength cardboard was also recovered suggests the compost retention time might not be sufficient to degrade these types of materials Recommendations The study found that the overwhelming majority of the plastics in the overs were non-degradable plastics As such limiting the distribution and promotion of truly compostable items will do little to reduce the total plastic in the overs stream Portland and its surrounding cities with food scraps collection programs need to address the prevalence of non-degradable plastic in the food scraps stream This can best be done through a targeted outreach program Outreach should be targeted at all sectors of the collection stream including generators vendors and collectors

4 Integrated Waste Management Consulting LLC Overs Sorting Study October 2012
1) Film Plastic which included any thin extruded plastic such as bags cup liners gloves wrappers etc (Please see Figures 3 amp 4)
2) Rigid Plastic This category included essentially all non-film plastic including hard plastic
cutlery plates etc 3) Other The other category included any non-plastic contaminants encountered in the overs
This included wet-strength cardboard glass wire rocks and other non-plastic items Interestingly though it was not documented for this study the ldquootherrdquo category included a significant amount of wet-strength cardboard (the type of cardboard that is commonly used to package some produce for grocery stores) This material would appear to be a challenge to fully breakdown during an abbreviated composting process Little effort was made to distinguish between the types of plastic encountered during the sorting process because visually distinguishing one type of plastic from another can be very difficult after the rigors of the composting process At the end of each subsample the recovered commodities were photographed weighed and bagged for shipment to a third-party laboratory (Advanced Materials Center ndash AMC) in Illinois for further laboratory analysis and identification (Please see Figures 5 amp 6) Five-gallon buckets were chosen as the sorting volume because they are a convenient and manageable size for this type of project Also there are roughly 40 five-gallon buckets in a cubic yard thus using five-gallon buckets allows for easy bulk density conversion However the relatively low bulk density of say film plastic does not really lend itself to weight-to-weight comparisons Thus the weight of the plastic itself is not the best way to represent the importance of the presence of this material in the overs Results Both of the selected compost sites use covered aerated static pile composting systems Both sites screen their finished compost after the composting process though one sitersquos screen used a one-pass type screen (which creates ldquooversrdquo and ldquofinesrdquo) and the other used a screen which made three products ndash overs ldquomiddlesrdquo and fines Plastics and other contaminants were encountered in all overs products and also in the ldquomiddlesrdquo product The results of the field sorting are summarized in Table 1 below The field sorting showed that the weight of plastics relative to the weight of the overs was not significant Also the weight of ldquootherrdquo contaminants was greater than the weight of all plastics removed Because of the two fractions at the first facility two distinct sorts were done ndash one of the overs one of the middle fraction However it is not valid to say that more or less contaminants were encountered at this facility but rather that more material was sorted thus a larger weight of contaminants was removed

13 Integrated Waste Management Consulting LLC Overs Sorting Study October 2012
Conclusions Based on IWMCrsquos experience the amount of all plastics removed from the overs at both facilities was comparable and fairly typical of composting facilities handling food scraps from relatively new collection programs The amounts of compostable plastics recovered ranged from 2 to 8 However it is clear based on AMCrsquos analysis that the composition of the plastic was overwhelmingly ldquoconventionalrdquo plastics (polyethylene polypropylene etc) While a small amount of compostable plastic was recovered in the overs it appears to be less than 4 of the total material analyzed by AMC While this could indicate that truly compostable plastics are breaking down significantly during the composting process at these two sites the study did not have any information on the ldquoupstreamrdquo volume of compostable plastics So it is impossible to make this conclusion The most prevalent plastics in the overs were film plastic consisting of two-thirds of the total sampled in the field Subsequent lab analysis showed these to be overwhelmingly made from non-biodegradable plastic (Polyethylene and Polypropylene) Less than one percent of the total samples of hard plastic were cutlery Approximately half of this consisted of starch and polypropylene and would not be expected to biodegrade or disintegrate The other half was identified as potentially compostable The study did not have enough data to determine why the cutlery might not be breaking down though the fact that large amounts of wet-strength cardboard was also recovered suggests the compost retention time might not be sufficient to degrade these types of materials Recommendations The study found that the overwhelming majority of the plastics in the overs were non-degradable plastics As such limiting the distribution and promotion of truly compostable items will do little to reduce the total plastic in the overs stream Portland and its surrounding cities with food scraps collection programs need to address the prevalence of non-degradable plastic in the food scraps stream This can best be done through a targeted outreach program Outreach should be targeted at all sectors of the collection stream including generators vendors and collectors

4 Integrated Waste Management Consulting LLC Overs Sorting Study October 2012
1) Film Plastic which included any thin extruded plastic such as bags cup liners gloves wrappers etc (Please see Figures 3 amp 4)
2) Rigid Plastic This category included essentially all non-film plastic including hard plastic
cutlery plates etc 3) Other The other category included any non-plastic contaminants encountered in the overs
This included wet-strength cardboard glass wire rocks and other non-plastic items Interestingly though it was not documented for this study the ldquootherrdquo category included a significant amount of wet-strength cardboard (the type of cardboard that is commonly used to package some produce for grocery stores) This material would appear to be a challenge to fully breakdown during an abbreviated composting process Little effort was made to distinguish between the types of plastic encountered during the sorting process because visually distinguishing one type of plastic from another can be very difficult after the rigors of the composting process At the end of each subsample the recovered commodities were photographed weighed and bagged for shipment to a third-party laboratory (Advanced Materials Center ndash AMC) in Illinois for further laboratory analysis and identification (Please see Figures 5 amp 6) Five-gallon buckets were chosen as the sorting volume because they are a convenient and manageable size for this type of project Also there are roughly 40 five-gallon buckets in a cubic yard thus using five-gallon buckets allows for easy bulk density conversion However the relatively low bulk density of say film plastic does not really lend itself to weight-to-weight comparisons Thus the weight of the plastic itself is not the best way to represent the importance of the presence of this material in the overs Results Both of the selected compost sites use covered aerated static pile composting systems Both sites screen their finished compost after the composting process though one sitersquos screen used a one-pass type screen (which creates ldquooversrdquo and ldquofinesrdquo) and the other used a screen which made three products ndash overs ldquomiddlesrdquo and fines Plastics and other contaminants were encountered in all overs products and also in the ldquomiddlesrdquo product The results of the field sorting are summarized in Table 1 below The field sorting showed that the weight of plastics relative to the weight of the overs was not significant Also the weight of ldquootherrdquo contaminants was greater than the weight of all plastics removed Because of the two fractions at the first facility two distinct sorts were done ndash one of the overs one of the middle fraction However it is not valid to say that more or less contaminants were encountered at this facility but rather that more material was sorted thus a larger weight of contaminants was removed

13 Integrated Waste Management Consulting LLC Overs Sorting Study October 2012
Conclusions Based on IWMCrsquos experience the amount of all plastics removed from the overs at both facilities was comparable and fairly typical of composting facilities handling food scraps from relatively new collection programs The amounts of compostable plastics recovered ranged from 2 to 8 However it is clear based on AMCrsquos analysis that the composition of the plastic was overwhelmingly ldquoconventionalrdquo plastics (polyethylene polypropylene etc) While a small amount of compostable plastic was recovered in the overs it appears to be less than 4 of the total material analyzed by AMC While this could indicate that truly compostable plastics are breaking down significantly during the composting process at these two sites the study did not have any information on the ldquoupstreamrdquo volume of compostable plastics So it is impossible to make this conclusion The most prevalent plastics in the overs were film plastic consisting of two-thirds of the total sampled in the field Subsequent lab analysis showed these to be overwhelmingly made from non-biodegradable plastic (Polyethylene and Polypropylene) Less than one percent of the total samples of hard plastic were cutlery Approximately half of this consisted of starch and polypropylene and would not be expected to biodegrade or disintegrate The other half was identified as potentially compostable The study did not have enough data to determine why the cutlery might not be breaking down though the fact that large amounts of wet-strength cardboard was also recovered suggests the compost retention time might not be sufficient to degrade these types of materials Recommendations The study found that the overwhelming majority of the plastics in the overs were non-degradable plastics As such limiting the distribution and promotion of truly compostable items will do little to reduce the total plastic in the overs stream Portland and its surrounding cities with food scraps collection programs need to address the prevalence of non-degradable plastic in the food scraps stream This can best be done through a targeted outreach program Outreach should be targeted at all sectors of the collection stream including generators vendors and collectors

4 Integrated Waste Management Consulting LLC Overs Sorting Study October 2012
1) Film Plastic which included any thin extruded plastic such as bags cup liners gloves wrappers etc (Please see Figures 3 amp 4)
2) Rigid Plastic This category included essentially all non-film plastic including hard plastic
cutlery plates etc 3) Other The other category included any non-plastic contaminants encountered in the overs
This included wet-strength cardboard glass wire rocks and other non-plastic items Interestingly though it was not documented for this study the ldquootherrdquo category included a significant amount of wet-strength cardboard (the type of cardboard that is commonly used to package some produce for grocery stores) This material would appear to be a challenge to fully breakdown during an abbreviated composting process Little effort was made to distinguish between the types of plastic encountered during the sorting process because visually distinguishing one type of plastic from another can be very difficult after the rigors of the composting process At the end of each subsample the recovered commodities were photographed weighed and bagged for shipment to a third-party laboratory (Advanced Materials Center ndash AMC) in Illinois for further laboratory analysis and identification (Please see Figures 5 amp 6) Five-gallon buckets were chosen as the sorting volume because they are a convenient and manageable size for this type of project Also there are roughly 40 five-gallon buckets in a cubic yard thus using five-gallon buckets allows for easy bulk density conversion However the relatively low bulk density of say film plastic does not really lend itself to weight-to-weight comparisons Thus the weight of the plastic itself is not the best way to represent the importance of the presence of this material in the overs Results Both of the selected compost sites use covered aerated static pile composting systems Both sites screen their finished compost after the composting process though one sitersquos screen used a one-pass type screen (which creates ldquooversrdquo and ldquofinesrdquo) and the other used a screen which made three products ndash overs ldquomiddlesrdquo and fines Plastics and other contaminants were encountered in all overs products and also in the ldquomiddlesrdquo product The results of the field sorting are summarized in Table 1 below The field sorting showed that the weight of plastics relative to the weight of the overs was not significant Also the weight of ldquootherrdquo contaminants was greater than the weight of all plastics removed Because of the two fractions at the first facility two distinct sorts were done ndash one of the overs one of the middle fraction However it is not valid to say that more or less contaminants were encountered at this facility but rather that more material was sorted thus a larger weight of contaminants was removed

Conclusions Based on IWMCrsquos experience the amount of all plastics removed from the overs at both facilities was comparable and fairly typical of composting facilities handling food scraps from relatively new collection programs The amounts of compostable plastics recovered ranged from 2 to 8 However it is clear based on AMCrsquos analysis that the composition of the plastic was overwhelmingly ldquoconventionalrdquo plastics (polyethylene polypropylene etc) While a small amount of compostable plastic was recovered in the overs it appears to be less than 4 of the total material analyzed by AMC While this could indicate that truly compostable plastics are breaking down significantly during the composting process at these two sites the study did not have any information on the ldquoupstreamrdquo volume of compostable plastics So it is impossible to make this conclusion The most prevalent plastics in the overs were film plastic consisting of two-thirds of the total sampled in the field Subsequent lab analysis showed these to be overwhelmingly made from non-biodegradable plastic (Polyethylene and Polypropylene) Less than one percent of the total samples of hard plastic were cutlery Approximately half of this consisted of starch and polypropylene and would not be expected to biodegrade or disintegrate The other half was identified as potentially compostable The study did not have enough data to determine why the cutlery might not be breaking down though the fact that large amounts of wet-strength cardboard was also recovered suggests the compost retention time might not be sufficient to degrade these types of materials Recommendations The study found that the overwhelming majority of the plastics in the overs were non-degradable plastics As such limiting the distribution and promotion of truly compostable items will do little to reduce the total plastic in the overs stream Portland and its surrounding cities with food scraps collection programs need to address the prevalence of non-degradable plastic in the food scraps stream This can best be done through a targeted outreach program Outreach should be targeted at all sectors of the collection stream including generators vendors and collectors

13 Integrated Waste Management Consulting LLC Overs Sorting Study October 2012
Conclusions Based on IWMCrsquos experience the amount of all plastics removed from the overs at both facilities was comparable and fairly typical of composting facilities handling food scraps from relatively new collection programs The amounts of compostable plastics recovered ranged from 2 to 8 However it is clear based on AMCrsquos analysis that the composition of the plastic was overwhelmingly ldquoconventionalrdquo plastics (polyethylene polypropylene etc) While a small amount of compostable plastic was recovered in the overs it appears to be less than 4 of the total material analyzed by AMC While this could indicate that truly compostable plastics are breaking down significantly during the composting process at these two sites the study did not have any information on the ldquoupstreamrdquo volume of compostable plastics So it is impossible to make this conclusion The most prevalent plastics in the overs were film plastic consisting of two-thirds of the total sampled in the field Subsequent lab analysis showed these to be overwhelmingly made from non-biodegradable plastic (Polyethylene and Polypropylene) Less than one percent of the total samples of hard plastic were cutlery Approximately half of this consisted of starch and polypropylene and would not be expected to biodegrade or disintegrate The other half was identified as potentially compostable The study did not have enough data to determine why the cutlery might not be breaking down though the fact that large amounts of wet-strength cardboard was also recovered suggests the compost retention time might not be sufficient to degrade these types of materials Recommendations The study found that the overwhelming majority of the plastics in the overs were non-degradable plastics As such limiting the distribution and promotion of truly compostable items will do little to reduce the total plastic in the overs stream Portland and its surrounding cities with food scraps collection programs need to address the prevalence of non-degradable plastic in the food scraps stream This can best be done through a targeted outreach program Outreach should be targeted at all sectors of the collection stream including generators vendors and collectors

13 Integrated Waste Management Consulting LLC Overs Sorting Study October 2012
Conclusions Based on IWMCrsquos experience the amount of all plastics removed from the overs at both facilities was comparable and fairly typical of composting facilities handling food scraps from relatively new collection programs The amounts of compostable plastics recovered ranged from 2 to 8 However it is clear based on AMCrsquos analysis that the composition of the plastic was overwhelmingly ldquoconventionalrdquo plastics (polyethylene polypropylene etc) While a small amount of compostable plastic was recovered in the overs it appears to be less than 4 of the total material analyzed by AMC While this could indicate that truly compostable plastics are breaking down significantly during the composting process at these two sites the study did not have any information on the ldquoupstreamrdquo volume of compostable plastics So it is impossible to make this conclusion The most prevalent plastics in the overs were film plastic consisting of two-thirds of the total sampled in the field Subsequent lab analysis showed these to be overwhelmingly made from non-biodegradable plastic (Polyethylene and Polypropylene) Less than one percent of the total samples of hard plastic were cutlery Approximately half of this consisted of starch and polypropylene and would not be expected to biodegrade or disintegrate The other half was identified as potentially compostable The study did not have enough data to determine why the cutlery might not be breaking down though the fact that large amounts of wet-strength cardboard was also recovered suggests the compost retention time might not be sufficient to degrade these types of materials Recommendations The study found that the overwhelming majority of the plastics in the overs were non-degradable plastics As such limiting the distribution and promotion of truly compostable items will do little to reduce the total plastic in the overs stream Portland and its surrounding cities with food scraps collection programs need to address the prevalence of non-degradable plastic in the food scraps stream This can best be done through a targeted outreach program Outreach should be targeted at all sectors of the collection stream including generators vendors and collectors

13 Integrated Waste Management Consulting LLC Overs Sorting Study October 2012
Conclusions Based on IWMCrsquos experience the amount of all plastics removed from the overs at both facilities was comparable and fairly typical of composting facilities handling food scraps from relatively new collection programs The amounts of compostable plastics recovered ranged from 2 to 8 However it is clear based on AMCrsquos analysis that the composition of the plastic was overwhelmingly ldquoconventionalrdquo plastics (polyethylene polypropylene etc) While a small amount of compostable plastic was recovered in the overs it appears to be less than 4 of the total material analyzed by AMC While this could indicate that truly compostable plastics are breaking down significantly during the composting process at these two sites the study did not have any information on the ldquoupstreamrdquo volume of compostable plastics So it is impossible to make this conclusion The most prevalent plastics in the overs were film plastic consisting of two-thirds of the total sampled in the field Subsequent lab analysis showed these to be overwhelmingly made from non-biodegradable plastic (Polyethylene and Polypropylene) Less than one percent of the total samples of hard plastic were cutlery Approximately half of this consisted of starch and polypropylene and would not be expected to biodegrade or disintegrate The other half was identified as potentially compostable The study did not have enough data to determine why the cutlery might not be breaking down though the fact that large amounts of wet-strength cardboard was also recovered suggests the compost retention time might not be sufficient to degrade these types of materials Recommendations The study found that the overwhelming majority of the plastics in the overs were non-degradable plastics As such limiting the distribution and promotion of truly compostable items will do little to reduce the total plastic in the overs stream Portland and its surrounding cities with food scraps collection programs need to address the prevalence of non-degradable plastic in the food scraps stream This can best be done through a targeted outreach program Outreach should be targeted at all sectors of the collection stream including generators vendors and collectors

13 Integrated Waste Management Consulting LLC Overs Sorting Study October 2012
Conclusions Based on IWMCrsquos experience the amount of all plastics removed from the overs at both facilities was comparable and fairly typical of composting facilities handling food scraps from relatively new collection programs The amounts of compostable plastics recovered ranged from 2 to 8 However it is clear based on AMCrsquos analysis that the composition of the plastic was overwhelmingly ldquoconventionalrdquo plastics (polyethylene polypropylene etc) While a small amount of compostable plastic was recovered in the overs it appears to be less than 4 of the total material analyzed by AMC While this could indicate that truly compostable plastics are breaking down significantly during the composting process at these two sites the study did not have any information on the ldquoupstreamrdquo volume of compostable plastics So it is impossible to make this conclusion The most prevalent plastics in the overs were film plastic consisting of two-thirds of the total sampled in the field Subsequent lab analysis showed these to be overwhelmingly made from non-biodegradable plastic (Polyethylene and Polypropylene) Less than one percent of the total samples of hard plastic were cutlery Approximately half of this consisted of starch and polypropylene and would not be expected to biodegrade or disintegrate The other half was identified as potentially compostable The study did not have enough data to determine why the cutlery might not be breaking down though the fact that large amounts of wet-strength cardboard was also recovered suggests the compost retention time might not be sufficient to degrade these types of materials Recommendations The study found that the overwhelming majority of the plastics in the overs were non-degradable plastics As such limiting the distribution and promotion of truly compostable items will do little to reduce the total plastic in the overs stream Portland and its surrounding cities with food scraps collection programs need to address the prevalence of non-degradable plastic in the food scraps stream This can best be done through a targeted outreach program Outreach should be targeted at all sectors of the collection stream including generators vendors and collectors

13 Integrated Waste Management Consulting LLC Overs Sorting Study October 2012
Conclusions Based on IWMCrsquos experience the amount of all plastics removed from the overs at both facilities was comparable and fairly typical of composting facilities handling food scraps from relatively new collection programs The amounts of compostable plastics recovered ranged from 2 to 8 However it is clear based on AMCrsquos analysis that the composition of the plastic was overwhelmingly ldquoconventionalrdquo plastics (polyethylene polypropylene etc) While a small amount of compostable plastic was recovered in the overs it appears to be less than 4 of the total material analyzed by AMC While this could indicate that truly compostable plastics are breaking down significantly during the composting process at these two sites the study did not have any information on the ldquoupstreamrdquo volume of compostable plastics So it is impossible to make this conclusion The most prevalent plastics in the overs were film plastic consisting of two-thirds of the total sampled in the field Subsequent lab analysis showed these to be overwhelmingly made from non-biodegradable plastic (Polyethylene and Polypropylene) Less than one percent of the total samples of hard plastic were cutlery Approximately half of this consisted of starch and polypropylene and would not be expected to biodegrade or disintegrate The other half was identified as potentially compostable The study did not have enough data to determine why the cutlery might not be breaking down though the fact that large amounts of wet-strength cardboard was also recovered suggests the compost retention time might not be sufficient to degrade these types of materials Recommendations The study found that the overwhelming majority of the plastics in the overs were non-degradable plastics As such limiting the distribution and promotion of truly compostable items will do little to reduce the total plastic in the overs stream Portland and its surrounding cities with food scraps collection programs need to address the prevalence of non-degradable plastic in the food scraps stream This can best be done through a targeted outreach program Outreach should be targeted at all sectors of the collection stream including generators vendors and collectors

Conclusions Based on IWMCrsquos experience the amount of all plastics removed from the overs at both facilities was comparable and fairly typical of composting facilities handling food scraps from relatively new collection programs The amounts of compostable plastics recovered ranged from 2 to 8 However it is clear based on AMCrsquos analysis that the composition of the plastic was overwhelmingly ldquoconventionalrdquo plastics (polyethylene polypropylene etc) While a small amount of compostable plastic was recovered in the overs it appears to be less than 4 of the total material analyzed by AMC While this could indicate that truly compostable plastics are breaking down significantly during the composting process at these two sites the study did not have any information on the ldquoupstreamrdquo volume of compostable plastics So it is impossible to make this conclusion The most prevalent plastics in the overs were film plastic consisting of two-thirds of the total sampled in the field Subsequent lab analysis showed these to be overwhelmingly made from non-biodegradable plastic (Polyethylene and Polypropylene) Less than one percent of the total samples of hard plastic were cutlery Approximately half of this consisted of starch and polypropylene and would not be expected to biodegrade or disintegrate The other half was identified as potentially compostable The study did not have enough data to determine why the cutlery might not be breaking down though the fact that large amounts of wet-strength cardboard was also recovered suggests the compost retention time might not be sufficient to degrade these types of materials Recommendations The study found that the overwhelming majority of the plastics in the overs were non-degradable plastics As such limiting the distribution and promotion of truly compostable items will do little to reduce the total plastic in the overs stream Portland and its surrounding cities with food scraps collection programs need to address the prevalence of non-degradable plastic in the food scraps stream This can best be done through a targeted outreach program Outreach should be targeted at all sectors of the collection stream including generators vendors and collectors

13 Integrated Waste Management Consulting LLC Overs Sorting Study October 2012
Conclusions Based on IWMCrsquos experience the amount of all plastics removed from the overs at both facilities was comparable and fairly typical of composting facilities handling food scraps from relatively new collection programs The amounts of compostable plastics recovered ranged from 2 to 8 However it is clear based on AMCrsquos analysis that the composition of the plastic was overwhelmingly ldquoconventionalrdquo plastics (polyethylene polypropylene etc) While a small amount of compostable plastic was recovered in the overs it appears to be less than 4 of the total material analyzed by AMC While this could indicate that truly compostable plastics are breaking down significantly during the composting process at these two sites the study did not have any information on the ldquoupstreamrdquo volume of compostable plastics So it is impossible to make this conclusion The most prevalent plastics in the overs were film plastic consisting of two-thirds of the total sampled in the field Subsequent lab analysis showed these to be overwhelmingly made from non-biodegradable plastic (Polyethylene and Polypropylene) Less than one percent of the total samples of hard plastic were cutlery Approximately half of this consisted of starch and polypropylene and would not be expected to biodegrade or disintegrate The other half was identified as potentially compostable The study did not have enough data to determine why the cutlery might not be breaking down though the fact that large amounts of wet-strength cardboard was also recovered suggests the compost retention time might not be sufficient to degrade these types of materials Recommendations The study found that the overwhelming majority of the plastics in the overs were non-degradable plastics As such limiting the distribution and promotion of truly compostable items will do little to reduce the total plastic in the overs stream Portland and its surrounding cities with food scraps collection programs need to address the prevalence of non-degradable plastic in the food scraps stream This can best be done through a targeted outreach program Outreach should be targeted at all sectors of the collection stream including generators vendors and collectors

13 Integrated Waste Management Consulting LLC Overs Sorting Study October 2012
Conclusions Based on IWMCrsquos experience the amount of all plastics removed from the overs at both facilities was comparable and fairly typical of composting facilities handling food scraps from relatively new collection programs The amounts of compostable plastics recovered ranged from 2 to 8 However it is clear based on AMCrsquos analysis that the composition of the plastic was overwhelmingly ldquoconventionalrdquo plastics (polyethylene polypropylene etc) While a small amount of compostable plastic was recovered in the overs it appears to be less than 4 of the total material analyzed by AMC While this could indicate that truly compostable plastics are breaking down significantly during the composting process at these two sites the study did not have any information on the ldquoupstreamrdquo volume of compostable plastics So it is impossible to make this conclusion The most prevalent plastics in the overs were film plastic consisting of two-thirds of the total sampled in the field Subsequent lab analysis showed these to be overwhelmingly made from non-biodegradable plastic (Polyethylene and Polypropylene) Less than one percent of the total samples of hard plastic were cutlery Approximately half of this consisted of starch and polypropylene and would not be expected to biodegrade or disintegrate The other half was identified as potentially compostable The study did not have enough data to determine why the cutlery might not be breaking down though the fact that large amounts of wet-strength cardboard was also recovered suggests the compost retention time might not be sufficient to degrade these types of materials Recommendations The study found that the overwhelming majority of the plastics in the overs were non-degradable plastics As such limiting the distribution and promotion of truly compostable items will do little to reduce the total plastic in the overs stream Portland and its surrounding cities with food scraps collection programs need to address the prevalence of non-degradable plastic in the food scraps stream This can best be done through a targeted outreach program Outreach should be targeted at all sectors of the collection stream including generators vendors and collectors

Determining the Amount of Plastic and Compostable Plastic in Compost ldquoOversrdquo
13 Integrated Waste Management Consulting LLC Overs Sorting Study October 2012
Conclusions Based on IWMCrsquos experience the amount of all plastics removed from the overs at both facilities was comparable and fairly typical of composting facilities handling food scraps from relatively new collection programs The amounts of compostable plastics recovered ranged from 2 to 8 However it is clear based on AMCrsquos analysis that the composition of the plastic was overwhelmingly ldquoconventionalrdquo plastics (polyethylene polypropylene etc) While a small amount of compostable plastic was recovered in the overs it appears to be less than 4 of the total material analyzed by AMC While this could indicate that truly compostable plastics are breaking down significantly during the composting process at these two sites the study did not have any information on the ldquoupstreamrdquo volume of compostable plastics So it is impossible to make this conclusion The most prevalent plastics in the overs were film plastic consisting of two-thirds of the total sampled in the field Subsequent lab analysis showed these to be overwhelmingly made from non-biodegradable plastic (Polyethylene and Polypropylene) Less than one percent of the total samples of hard plastic were cutlery Approximately half of this consisted of starch and polypropylene and would not be expected to biodegrade or disintegrate The other half was identified as potentially compostable The study did not have enough data to determine why the cutlery might not be breaking down though the fact that large amounts of wet-strength cardboard was also recovered suggests the compost retention time might not be sufficient to degrade these types of materials Recommendations The study found that the overwhelming majority of the plastics in the overs were non-degradable plastics As such limiting the distribution and promotion of truly compostable items will do little to reduce the total plastic in the overs stream Portland and its surrounding cities with food scraps collection programs need to address the prevalence of non-degradable plastic in the food scraps stream This can best be done through a targeted outreach program Outreach should be targeted at all sectors of the collection stream including generators vendors and collectors

PO S Mojo Purpose Review the contents of supplied bags containing films hard plastics and possible compostable materials to determine material composition using FTIR infrared analysis visual examination and burn tests Evaluate and quantify non-compostable items and compostable items gathered from the Naturersquos Needs and Portland Recycling Center Sample Identification Source A-P Bags of Samples 16 total per Table PRC amp Naturersquos Needs Oregon Refer to Table I for Individual Bag Sample Identification Conclusions In our opinion based on the combination of FTIR burn analysis and visual examination the Sixteen (16) Bags of samples contain primarily non-compostable materials such as PP PE PS and PVC A small amount of the observed specimens were composed of potentially compostable materials such as cellulose starch and polyester based resins Results Refer to Tables I-II for Individual Bag Content
Bag 1 NN1 Film Plastics Approximately 95 of the contents observed in this bag were composed of non-compostable material This included PE PP PVC Nylon and Vinyl The remaining contents (~5) were composed of potentially compostable materials This includes cellulose and starch FTIR spectra are attached Bag 2 Film Plastic NN2 Approximately 98 of the samples observed in this bag were non-biodegradable The 98 was comprised of PEPP Bags and latex gloves The remaining ~2 was composed of cellulose and regenerated cellulose which have potential of composting Bag 3 Hard Plastic NN1 Bag 3 contained 100 non-compostable materials PE PP PVC Inert Material (glass rocks) Nylon PS and Latex made up the non-compostable materials
Bag 4 NN1 ndash Other Plastics Approximately 98 of the contents observed in this bag were composed of non-compostable material This included PP PE and Latex The remaining contents (~2) were composed of potentially compostable materials This includes starch and a polyester based resin FTIR spectra are attached Bag 5 NN2 ndash Other Plastics Bag 5 contained 100 non-compostable material This included PE FTIR spectra are attached
Bag 6 Film Plastic ndash Middles and Gross Overs PRC 1 Approximately 97 of the contents observed in this bag were composed of non-compostable material This included PP PE Latex and Nylon The remaining contents (~3) were composed of potentially compostable materials This includes cellulose and regenerated cellulose Bag 7 Film Plastic ndash Gross Overs PRC 2 Approximately 87 of the contents observed in this bag were composed of non-compostable material This included PE PP Latex and PS The remaining contents (~13) were composed of potentially compostable materials This includes cellulose cellulose acetate and regenerated cellulose Bag 8 Film Plastic ndash Gross Overs PRC 3 Approximately 96 of the contents observed in this bag were composed of non-compostable material This included PP PE and Latex The remaining contents (~4) were composed of potentially compostable materials This included cellulose Bag 9 Hard plastic ndash Gross Overs PRC 1 Approximately 99 of the contents observed in this bag were composed of non-compostable material This included PP PE Rubber (EPDM) Nylon PVC and Copper The remaining contents (~1) were composed of potentially compostable materials This included cellulose acetate Bag 10 Hard plastic ndash Gross Overs PRC 2 Bag 10 contained 100 non-compostable material This included PE PP and Latex Bag 11 Hard plastic ndash Gross Overs PRC 3 Approximately 99 of the contents observed in this bag were composed of non-compostable material This included PP PE PET Latex Glass and Metal The remaining contents (~1) were composed of potentially compostable materials This included cellulose Bag 12 Possible Compostable Gross Overs PRC Approximately 70 of the contents observed in this bag were composed of non-compostable material This included PP The remaining contents (~30) were composed of potentially compostable materials This included cellulose which was the majority and polyester FTIR spectra are attached

PO S Mojo Purpose Review the contents of supplied bags containing films hard plastics and possible compostable materials to determine material composition using FTIR infrared analysis visual examination and burn tests Evaluate and quantify non-compostable items and compostable items gathered from the Naturersquos Needs and Portland Recycling Center Sample Identification Source A-P Bags of Samples 16 total per Table PRC amp Naturersquos Needs Oregon Refer to Table I for Individual Bag Sample Identification Conclusions In our opinion based on the combination of FTIR burn analysis and visual examination the Sixteen (16) Bags of samples contain primarily non-compostable materials such as PP PE PS and PVC A small amount of the observed specimens were composed of potentially compostable materials such as cellulose starch and polyester based resins Results Refer to Tables I-II for Individual Bag Content
Bag 1 NN1 Film Plastics Approximately 95 of the contents observed in this bag were composed of non-compostable material This included PE PP PVC Nylon and Vinyl The remaining contents (~5) were composed of potentially compostable materials This includes cellulose and starch FTIR spectra are attached Bag 2 Film Plastic NN2 Approximately 98 of the samples observed in this bag were non-biodegradable The 98 was comprised of PEPP Bags and latex gloves The remaining ~2 was composed of cellulose and regenerated cellulose which have potential of composting Bag 3 Hard Plastic NN1 Bag 3 contained 100 non-compostable materials PE PP PVC Inert Material (glass rocks) Nylon PS and Latex made up the non-compostable materials
Bag 4 NN1 ndash Other Plastics Approximately 98 of the contents observed in this bag were composed of non-compostable material This included PP PE and Latex The remaining contents (~2) were composed of potentially compostable materials This includes starch and a polyester based resin FTIR spectra are attached Bag 5 NN2 ndash Other Plastics Bag 5 contained 100 non-compostable material This included PE FTIR spectra are attached
Bag 6 Film Plastic ndash Middles and Gross Overs PRC 1 Approximately 97 of the contents observed in this bag were composed of non-compostable material This included PP PE Latex and Nylon The remaining contents (~3) were composed of potentially compostable materials This includes cellulose and regenerated cellulose Bag 7 Film Plastic ndash Gross Overs PRC 2 Approximately 87 of the contents observed in this bag were composed of non-compostable material This included PE PP Latex and PS The remaining contents (~13) were composed of potentially compostable materials This includes cellulose cellulose acetate and regenerated cellulose Bag 8 Film Plastic ndash Gross Overs PRC 3 Approximately 96 of the contents observed in this bag were composed of non-compostable material This included PP PE and Latex The remaining contents (~4) were composed of potentially compostable materials This included cellulose Bag 9 Hard plastic ndash Gross Overs PRC 1 Approximately 99 of the contents observed in this bag were composed of non-compostable material This included PP PE Rubber (EPDM) Nylon PVC and Copper The remaining contents (~1) were composed of potentially compostable materials This included cellulose acetate Bag 10 Hard plastic ndash Gross Overs PRC 2 Bag 10 contained 100 non-compostable material This included PE PP and Latex Bag 11 Hard plastic ndash Gross Overs PRC 3 Approximately 99 of the contents observed in this bag were composed of non-compostable material This included PP PE PET Latex Glass and Metal The remaining contents (~1) were composed of potentially compostable materials This included cellulose Bag 12 Possible Compostable Gross Overs PRC Approximately 70 of the contents observed in this bag were composed of non-compostable material This included PP The remaining contents (~30) were composed of potentially compostable materials This included cellulose which was the majority and polyester FTIR spectra are attached
Bag 13 Hard Plastic ndash Middles PRC 4 Approximately 99 of the contents observed in this bag were composed of non-compostable material This included PP PE PS Nylon and Rubber The remaining contents (~1) were composed of potentially compostable materials This included cellulose

PO S Mojo Purpose Review the contents of supplied bags containing films hard plastics and possible compostable materials to determine material composition using FTIR infrared analysis visual examination and burn tests Evaluate and quantify non-compostable items and compostable items gathered from the Naturersquos Needs and Portland Recycling Center Sample Identification Source A-P Bags of Samples 16 total per Table PRC amp Naturersquos Needs Oregon Refer to Table I for Individual Bag Sample Identification Conclusions In our opinion based on the combination of FTIR burn analysis and visual examination the Sixteen (16) Bags of samples contain primarily non-compostable materials such as PP PE PS and PVC A small amount of the observed specimens were composed of potentially compostable materials such as cellulose starch and polyester based resins Results Refer to Tables I-II for Individual Bag Content
Bag 1 NN1 Film Plastics Approximately 95 of the contents observed in this bag were composed of non-compostable material This included PE PP PVC Nylon and Vinyl The remaining contents (~5) were composed of potentially compostable materials This includes cellulose and starch FTIR spectra are attached Bag 2 Film Plastic NN2 Approximately 98 of the samples observed in this bag were non-biodegradable The 98 was comprised of PEPP Bags and latex gloves The remaining ~2 was composed of cellulose and regenerated cellulose which have potential of composting Bag 3 Hard Plastic NN1 Bag 3 contained 100 non-compostable materials PE PP PVC Inert Material (glass rocks) Nylon PS and Latex made up the non-compostable materials
Bag 4 NN1 ndash Other Plastics Approximately 98 of the contents observed in this bag were composed of non-compostable material This included PP PE and Latex The remaining contents (~2) were composed of potentially compostable materials This includes starch and a polyester based resin FTIR spectra are attached Bag 5 NN2 ndash Other Plastics Bag 5 contained 100 non-compostable material This included PE FTIR spectra are attached
Bag 6 Film Plastic ndash Middles and Gross Overs PRC 1 Approximately 97 of the contents observed in this bag were composed of non-compostable material This included PP PE Latex and Nylon The remaining contents (~3) were composed of potentially compostable materials This includes cellulose and regenerated cellulose Bag 7 Film Plastic ndash Gross Overs PRC 2 Approximately 87 of the contents observed in this bag were composed of non-compostable material This included PE PP Latex and PS The remaining contents (~13) were composed of potentially compostable materials This includes cellulose cellulose acetate and regenerated cellulose Bag 8 Film Plastic ndash Gross Overs PRC 3 Approximately 96 of the contents observed in this bag were composed of non-compostable material This included PP PE and Latex The remaining contents (~4) were composed of potentially compostable materials This included cellulose Bag 9 Hard plastic ndash Gross Overs PRC 1 Approximately 99 of the contents observed in this bag were composed of non-compostable material This included PP PE Rubber (EPDM) Nylon PVC and Copper The remaining contents (~1) were composed of potentially compostable materials This included cellulose acetate Bag 10 Hard plastic ndash Gross Overs PRC 2 Bag 10 contained 100 non-compostable material This included PE PP and Latex Bag 11 Hard plastic ndash Gross Overs PRC 3 Approximately 99 of the contents observed in this bag were composed of non-compostable material This included PP PE PET Latex Glass and Metal The remaining contents (~1) were composed of potentially compostable materials This included cellulose Bag 12 Possible Compostable Gross Overs PRC Approximately 70 of the contents observed in this bag were composed of non-compostable material This included PP The remaining contents (~30) were composed of potentially compostable materials This included cellulose which was the majority and polyester FTIR spectra are attached
Bag 13 Hard Plastic ndash Middles PRC 4 Approximately 99 of the contents observed in this bag were composed of non-compostable material This included PP PE PS Nylon and Rubber The remaining contents (~1) were composed of potentially compostable materials This included cellulose
