Par-Pak and the Environment
We, at Par-Pak, understand that sustainability is one of the most important issues that we face today. Our goal is to offer our customers products that are economical, functional and environmentally friendly. We are committed to working towards sustainability.
Par-Pak and the Environment
Sustainability is a mutual partnership between our customers and our vendors. We are working with them to offer options that will help us in our journey to becoming a more environmentally friendly company.
Our Environmental Policy, is the foundation of our organization’s responsibility to protect the environment.
Our Environmental Purchasing Policy, establishes our partnership with our vendors
We have outlined initiatives that will help us achieve our goals.
Product Development
With all plastic packaging, the three cornerstones of minimizing environmental impact are REDUCE, REUSE, and RECYCLE. Par-Pak containers meet all criteria
New products are developed to function with the thinnest gauge possible, while still meeting our customers’ objectives. Existing items can be reengineered in an effort to reduce the impact on the waste stream while maintaining the functionality of the product
Product Development (cont’d)
Our containers can be reused with simple hand washing and drying and are perfect for home use, including storing leftovers
Par-Pak manufactures thermoplastic containers in two different materials – Oriented Polystyrene (OPS) and Polyethylene Terephthalate (PETE).
Both types of plastics lend themselves to recycling. Internally, all material waste is ground up and re-extruded into new material.
Product Development (cont’d)
Both plastics are also recycled post-consumer through curbside collection where facilities are in place to sort and segregate
Par-Pak is active in the plastics industry to work with government and waste management groups to develop more plastics recycling across North America.
Education
Par-Pak believes that it’s important to educate our customers as well as our employees about the life cycle of our products. We believe that this information will empower them to make educated choices with respects to packaging and waste reduction. We offer information on:
- Material options – functionality and affordability
- Par-Pak has taken the initiative to remind our employees about Energy Conservation & Waste Reduction through monthly updates – See Example Click Here

The Greener Side of Par-Pak
Introduction
The Greener Side of Par-Pak presents the improvements in the technology here at Par-Pak Ltd. that will help in furthering our environmental initiatives. These include new technologies that help us conserve energy, conserve water, reduce carbon emissions and divert waste from the landfill.
The following are specific examples of the projects undertaken.
Terms
Extrusion/Distribution Centre – 26 Victoria Cr.
Thermoforming Plant 1 – 391 Orenda Rd.
Thermoforming Plant 2 – 376 Orenda Rd.
Tool and Die – 387 Orenda Rd.
Distribution Centre – 200 Summerlea Rd.
Energy Management
Incorporated various energy management tools to analyze the current state of energy consumption at Par-Pak Ltd. and to provide future goals and targets that will help in reduce the consumption of energy
CPIA – Energy Assessment SMART – Energy Audit CME – Energy Benchmark Study
Lighting
High efficiency T5 lighting installed at the two thermoforming plants in the summer of 2007
It saved approx. 228,000 kWh* of electricity at the Thermoforming Plant 2 in 2008 or 55% of the energy required to light the conventional metal halides
Savings of 610,000 kWh* (assuming 50% usage) per year are expected after the installation at the warehouse
T5 1 min. sensor lighting in Extrusion further saved approx. 185,000 kWh* (assuming 50% usage) of electricity in 2008
The increase in the quality of light provides a safer working environment and thus improving the overall productivity
(*see Appendix for calculation)
Heating
High efficiency tube heaters warm up the plant during the winter months at Thermoforming Plant 2 and the warehouse
After the recent installation at Thermoforming Plant 2 in 2008, an estimated 161,000 m3 in natural gas savings* per year are expected
That’s one-third of the amount required for the old, less efficient, heating systems
Greater quality of heat from the infrared energy is produced uniformly throughout the tube
At the Distribution Centre 3 tube heaters were placed in the summer of 2008 and 1 tube heater January 2009
(*see Appendix for calculation)
Fluid Cooling System
A new fluid cooling system at Thermoforming Plant 2 operates by reusing water, thereby reducing the consumption of water
The previously operating fluid cooling system lost a considerable amount of water to evaporation and had a capacity of 116 tons
The new energy saving fluid cooling system loses no water, except when changing molds where 5-10 gallons of water is lost, depending on the machine
The closed-loop concept is also adopted for the cooling system at Thermoforming Plant 1 where water consumption is reduced by 50%
Fluid Cooling System(cont.)
The new cooling system has the capacity of 140 tons and reaches all the machines in the plant requiring cooled water, unlike the old chiller system
Its 300 hp motor is highly efficient The system was operating from January 2009
Fluid Cooling System(cont.)
The energy saving cooler, a major part of the cooling system at Thermoforming Plant 2

Compressor
A new high efficiency compressor with high efficiency motor installed at Thermoforming Plant 1
The heat recovered from the compressor is a major contributor to the heating provided in the plant
10,437,350,400 Btu per year* in energy savings The old 300 hp compressors were water-cooled and
consumed 26 m3 of water per day in summer and 18 m3 of water in winter
Water leaks were evident in the old system
Compressor (cont.)
The new system in the whole process uses 5m3, but the compressor itself does not consume any water
The quality of air that reached the machines was free of oil-mist or any other contaminations
System installed November 2008
*(see Appendix for calculation)

Dock Area Insulation
R-10 insulation added to the inner docking area at Thermoforming Plant 1 accomplishes in giving a 30°C greater indoor temperature compared to the outdoor
– R- value is a measure of thermal resistance and the greater the value, the greater the resistance to the warm air escaping
– To make certain that the heat produced from the existing 130,000 Btu/hr heater did not escape, a roll-in door was put in so the insulated portion of the dock remained 30°C greater
– Installation: Fall 2008

Transportation
We are reviewing ways to reduce carbon emissions by reducing the number of trucks on the road:
Resin Delivery – Shipping of resin pellets to the Extrusion Plant from our suppliers
Inter-Company Delivery – Shipping of post-industrial trim between our Thermoforming Plants and Extrusion Plant
Transportation – Resin Delivery
Par-Pak used to take delivery of resin by tanker truck
In our new distribution centre, we are now able to take delivery of resin by rail, thus reducing truck travel by 74%
Reduces carbon footprint by an estimated 50 tonnes per year
Transportation – Resin Delivery
Stationary railcar at the distribution Centre
Transportation – Inter-Company
Trim scrap was shipped to be ground up in Extrusion Plant
Installation of grinders at our Thermoforming Plants reduced the number truck shipments by 80%
Carbon Reduction estimate of 1.5 tonnes per year Use of tankers will further reduce truck shipments by
95% (Thermoforming Plant 2) Carbon Reduction estimate of 0.5 tonnes per year
Transportation – Inter-Company

Appendix - Sample Calculations
Lighting Calculation: # Of fixtures: 121# Of fixtures before (assumption): 121Load for T5: 240 WLoad for Metal Halides (MH): 455 W# hours of operation (assumption)/year: 8760 h (365 days)Before: Energy consumed = (# of fixtures x # hours of operation x Load MH) 1000
= (121 x 8760 x 455) 1000 = 482281.8 kWh
After: Energy consumed = (# of fixtures x # hours of operation x Load MH) 1000
= (121 x 8760 x 240) 1000 = 254390.4 kWhDifference:
Energy Consumed Before – Energy Consumed After = 482281.8 – 254390.4 = 227891.4 kWh
Appendix - Sample Calculations
Tube Heating calculation:Assumptions: Conversion data:Heating runs (5 months/year-3650 hrs)- full capacity at 10% BTU kWh: 3,412.3BTU/kWh
- half capacity at 50% kWh m3: 10.83 kWh/m3 (Natural gas) - zero capacity at 40%
Total time running: (3650 x 0.1) + (0.5 x 3650)(0.5) + (0 x 3650) = 1,277.5 hrsFull capacity of Air-O-Mix systems (2): 6,875,000 BTU/hr Full capacity of Tube heaters (20): 2,215,514 BTU/hr
Initial heating system: Gas usage = Total capacity ÷ 3,412.3BTU/kWh x total time running ÷ 10.83 kWh/m3
= (6,875,000) ÷ 3,412.3 x (1,277.5) ÷ 10.83 = 237,661 m3
Tube Heating:Gas usage = Total capacity ÷ 3,412.3BTU/kWh x total time running ÷ 10.83 kWh/m3
= (2,215,514) ÷ 3,412.3 x (1,277.5) ÷ 10.83 = 76,587.83 m3
Difference: Old Heating System – Tube Heating = 237,661 – 76,587.83 = 161,073.2 m3
Appendix – Sample Calculations
Compressor Calculation 1:
Recoverable heat as a percentage of the unit’s output: 80% = 0.80
Compressor bhp: 600 bhp
Conversion factor: 2,545 Btu/bhp-hour
Hours of operation: 3 shifts/365 days = (365-9) x 24 = 8,544 hours
Energy Savings = 0.80 x compressor bhp x conversion factor x hours of operation = 0.80 x (600) x (2,545) x (8,544)
= 10,437,350,400 Btu per year
Appendix - Sample Calculations
Compressor Calculation 2:
Efficiency of waste heat displacing heat produced by natural gas: 85% = 0.85
Energy savings: 10,437,350,400 Btu per year
Btu/unit of fuel: 100,000 Btu/therm
$/unit fuel: $0.40/therm
Cost Savings = Energy savings ÷ Btu/unit fuel x $/unit fuel ÷ % efficiency
= (10,437,350,400) ÷ (100,000) x (0.40) ÷ 0.85
= $49,116.94
