At PFB Corporation, we are concerned with the future of the planet and the effects that modern life styles may be having on climate change. PFB Corporation is committed to conducting its operations responsibly, mindful of the economic, environmental and social impacts of its operations.
PFB reports the material impacts our activity has on the environment. We tabulate and report our emissions, energy usage and waste generated. In 2013 PFB established a Sustainability Committee with members from all areas and specialties within our company. The Committee’s mandate is to work with our management group and employees to facilitate continuous improvement of our sustainability performance. Our focus continues to be on improving our performance through a process of continuous improvement.
Green House Gas (GHG) – greenhouse gases are those gases which contribute to global warming. According to the Kyoto protocol significant greenhouse gases, emitted by human activity, include carbon dioxide (C02), methane (CH4), nitrous oxide (N20), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and sulphur hexafluoride (SF6).
Ozone Depleting Substance (ODS) – A chemical compound that reaches the stratosphere and is capable of reacting with stratospheric ozone causing it to be depleted. Stratospheric ozone protects the earth from harmful UV radiation. PFB does not emit harmful ozone depleting substances from our manufacturing processes.
Volatile Organic Compounds (VOC) – any organic compound that can become vaporized under normal atmospheric conditions. VOC can contribute to the creation of ground level smog around urban centers. PFB releases VOC’s as part of our foam insulation production processes and we are sensitive to this issue and are actively working towards reductions in the amount of VOC’s we emit.
Waste is a significant issue for manufacturers like PFB both from a cost perspective and its environmental impact. PFB is continually looking for ways to reduce the generation of waste and, wherever possible, reuse and recycle. In 2022 we experienced a significant increase in waste to landfills over the previous year. The cause of this increase was due to an increase in production in some divisions. However, increased production levels does not account for the entire waste increase and we are investigating further to determine areas for waste reduction and recycling.
Both direct electricity usage and natural gas consumption was relatively unchanged in 2022 (<5% change). Energy consumption has been a significant focus of our individual facilities as we work toward improving efficiencies through installation of energy efficient lighting, equipment and implementing administrative controls for managing equipment operation schedules.
The energy savings potential from using PFB’s insulating products over the expected lifetime of those products (assumed to be 50 years) exceeds the amount of energy consumed in the manufacturing process by a ratio of approximately 120:1

Estimates based on data in “Energy and Greenhouse Gas Savings for EPS Foam Insulation Applied to Exterior Walls of Single Family Residential Housing In the U.S. and Canada”, Franklin Associates Ltd. February 2009. Energy savings based on reduction in heating when insulation installed as per assumptions in the Franklin report. Note that other insulation materials will provide equivalent reduction in energy and GHG savings if installed to the same level of thermal performance.
(2) Production energy includes embodied energy in raw materials as per “Energy and Environmental Profile of the US Chemical Industry” (May 2000 by Energetics Inc. for US Department of Energy) and direct production energy to manufacture in process raw materials and finished products.
We measure and monitor the total amount of electricity and natural gas consumed by our operations. Electricity usage remained unchanged in 2022 over the previous year and natural gas decreased marginally.
Electrical Notes - Electricity (green bars) refer to the left vertical axis, natural gas consumption (blue bars) refer to the right vertical axis. Fuel Used for Manufacturing refers to Natural gas and biomass to create steam for production process and heat for general building heat and process heat.
Water consumption decreased slightly in 2022 over the previous year due in part with water reduction strategies and fluctuating production rates. The rate of water use per material output went down slightly due to gains in utilities usage efficiencies. Previous gains made in water conservation projects in the past continue to provide efficient use of water resources.
Over the past 10 years, PFB has completed several capital and research projects to substitute raw material inputs with materials that contain less VOC expanding agent. By substituting the raw materials PFB has made significant improvements in our VOC emissions intensity over the past several years.
The key emissions that we track are GHG’s, VOCs, NOx and SOx. We monitor emissions as a ratio of tonnes emitted to tonnes of EPS foam produced. Reductions in the ratios indicate better performance.
Since 2008 we have reduced VOC emissions intensity due to efforts to introduce raw materials with lower VOC content. PFB’s long term plan is to continue converting applications and manufacturing facilities over to the lower VOC raw materials to continuously improve our impact on the environment. In 2008, 13% of our raw materials consumed contained reduced levels of VOCs. In 2010 we successfully increased the usage of low VOC alternative raw material to 59% of the total input. In 2022 the usage of low VOC alternative raw material was >70% of the total resin input. This effort has resulted in an average VOC emissions reduction of over 100 tonnes annually and a total reduction of 1000 tonnes over the past 10 years (compared to emissions from using higher VOC raw materials).
Carbon dioxide, the principal greenhouse gas (GHG) emitted from PFB operations, arises from burning natural gas and other fuels in our production operations. We calculate and report GHG emissions in metric tonnes CO2 equivalents. Direct GHG emissions from PFB operations in 2022 was relatively unchanged over the previous year but emissions intensity decreased slightly.
Our insulating products provide customers with the means to reduce their energy consumption and, consequently, their GHG emissions. The estimated GHG reductions that could be achieved if EPS insulation products made by PFB in 2022 were applied to exterior walls of single family residential houses in Canada would be approximately 50,000 metric tonne annually (a ratio of 5 to 1). Through improvements in the energy-efficiency of our processes we continue to focus on reducing our GHG emissions to further improve the net benefits provided by our products.
