Par pak and the environment

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 environment1

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

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

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 d1

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

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:

Introduction

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

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

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

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

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 161,000m3 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

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

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

Compressor

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

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

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

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

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

Appendix sample calculations

Appendix - Sample Calculations

Lighting Calculation:

# Of fixtures: 121

# Of fixtures before (assumption): 121

Load for T5: 240 W

Load 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 kWh

Difference:

Energy Consumed Before – Energy Consumed After

= 482281.8 – 254390.4

= 227891.4 kWh


Appendix sample calculations1

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 hrs

Full 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 calculations2

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 calculations3

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
