Handouts SimaPro: Life Cycle Assessment software
(Exercise 1 and 6.1 are for beginners)
Case 1: plastic water bottle
1. Model water bottle using processes
1.1 Model a material: water bottle, cap
The production of a water bottle consists of a bottle, a cap and bottling process
20gr of plastic bottle Input/Output Input in SimaPro
1. Materials/fuels
22gr of PET Polyethylene terephthalate, granulate, bottle grade, at plant/RER S
Blow molding of the plastic Blow moulding/RER S
Outputs. Treatment 2g waste during the production
Disposal, polyethylene terephtalate, 0.2% water, to municipal incineration/CH S
3gr of plastic cap Input/Output Input in SimaPro
2. Materials/fuels 3.75 ABS Acrylonitrile-butadiene-styrene copolymer,
ABS, at plant/RER S
Outputs. Treatment 0.75gr of waste during production
Disposal, plastics, mixture, 15.3% water, to municipal incineration/CH S
1.2 Combine your materials: water bottle plus cap
1p of plastic bottle Input/Output Input in SimaPro
3. Materials/fuels/electricity
20gr of bottle See section 1.1
3gr of cap See section 1.1
Pumping, purifying, and filling
0.02 kWh Electricity, medium voltage, production UCTE, at grid/UCTE S
1.3 Model the life cycle
1p life cycle Input/Output Input in SimaPro
4. Materials/fuels Water bottle plus cap See section 1.2
100km of transport Transport, lorry 20-28t, fleet average/CH S
Outputs. Treatment Disposal of the bottle to incineration
Disposal, plastics, mixture, 15.3% water, to municipal incineration/CH S
2. Model water bottle using product stages
Model the same water bottle as above, but use this time product stages. In case you skip section 1, model both bottle and plastic cap as described in section 1.1.

Assembly bottle+cap Input/Output Input in SimaPro
Materials/assemblies 20gr of bottle See section 1.1
3gr of cap See section 1.1
Processes Pumping, purifying, and filling
Electricity, medium voltage, production UCTE, at grid/UCTE S
LC bottle+cap Input/Output Input in SimaPro
Assembly 1p of bottle+cap See section 2
Processes 100km of transport Transport, lorry 20-28t, fleet average/CH S
Waste/disposal scenario
Disposal of the bottle to incineration
Incineration/CH S
Case 2: glass water bottle
Model consistent with the plastic bottle, so that both life cycles can be compared!
3. Model the materials: glas bottle, aluminium cap
200gr of glass bottle Input/Output Input in SimaPro
5. Information
200gr primary glass Packaging glass, white, at plant/CH U
Glass blowing: 0.01kWh electricity
Search for the best process
10 gr waste during production goes to incineration
Search for the best process
5gr of aluminum cap Input/Output Input in SimaPro
6. Information 5gr primary aluminum Search for the best process
Production process Search for the best process
4. Model the assembly and life cycle, using product stages
Assembly and life cycle
Input/Output Input in SimaPro
7. Information
0.02 kWh for bottling process Search for the best process
Model the life cycle consistent with the water bottle so that both can be compared
Material, transport, waste Search for the best processes
5. Compare plastic bottle and glass bottle
Run a comparison and analyse where the difference comes from.

6. Model with parameters (apply to plastic bottle)
6.1 Model bottling with parameters
Parameter name Input value Comment
Input parameter pumping&cleaning 0.015 Fill in
Input parameter filling 0.005 Fill in
Calculated parameter bottling Pumping&cleaning+filling Fill in
6.2 Model transport with parameters
Parameter name Input value Comment
Input parameter distance Fill in Fill in
Input parameter weight_water Fill in Fill in
Input parameter weight_bottle Fill in Fill in
Calculated parameter transport Fill in Fill in
6.3 Different distances-different transport
Set up 3 scenarios: local, regional, abroad
Scenario Distance Transport mode
Local Smaller or equal than 50km van < 3,5t/RER S Regional Between 50 and 150km Lorry of 16t, fleet average/RER Abroad Bigger or equal than 150km Lorry of 20-28t, fleet average/RER
Compare the effect of different types of transport by making a calculation setup and defining different scenarios!!
