The third week of September annually is celebrated as Pollution Prevention, or P2, Week. P2 Week 2025 is September 15-21 using the theme: “40 Years of Pollution Prevention: Honoring the Past, Protecting the Future!”
As defined by the National Pollution Prevention Roundtable (NPPR, emphasis added), “Pollution is the contamination of air, soil, or water by the discharge of harmful substances. Pollution prevention is the reduction or elimination of pollution at the source (source reduction) instead of at the end-of-the-pipe or stack. Pollution prevention occurs when raw materials, water, energy and other resources are utilized more efficiently, when less harmful substances are substituted for hazardous ones, and when toxic substances are eliminated from the production process. By reducing the use and production of hazardous substances, and by operating more efficiently we protect human health, strengthen our economic well-being, and preserve the environment.”
Rather than being a burden on industry, NPPR points out that “Adopting pollution prevention practices and techniques often benefits industry by lowering a company’s operational and environmental compliance costs. By preventing the generation of waste, P2 can also reduce or eliminate long-term liabilities and clean-up costs. Furthermore, disposal costs are reduced when the volume of waste is decreased. This can also lead to a reduction in workplace exposures to hazardous materials which can affect workers’ health and hence, their productivity. If less waste is produced, there will also be a diminished need for on-site storage space. Furthermore, by preventing pollution there will be a greater likelihood that a company will be in compliance with local, state, and federal compliance statutes. Finally, as community pillars, businesses shoulder an important responsibility for protecting the environment and natural resources for their own good as well as that of society.”
In 1990, Congress passed the Pollution Prevention Act (P2Act), which states “The Environmental Protection Agency must establish a source reduction program which collects and disseminates information, provides financial assistance to States, and implements the other activities….”
The technical assistance experts within ISTC’s Center for Economic Impacts and Societal Benefits (CEISB) help businesses, organizations, institutions, and government agencies throughout Illinois and beyond prevent pollution and use resources more efficiently. This benefits our shared environment while also ensuring that companies and communities are more competitive and resilient.
CEISB technical assistance providers currently have federal funding to provide P2 assistance at no cost to certain industrial or market sectors. See the following brief descriptions and links to project flyers:
- Advancing Beverage Resilience through Pollution Prevention. This collaboration with EnergySense Resilience Center supports breweries, wineries, distilleries, and other craft beverage businesses across the state of Illinois. Following their assessments, participants will also have the chance to assist in shaping the certification process for green beverage manufacturing in Illinois and to be recognized for their sustainability efforts through the Illinois Green Business Program.
- Mississippi River Corridor Pollution Prevention. ISTC staff are working with partners at the Iowa Department of Natural Resources Office of Pollution Prevention Services and Missouri State University to provide free industrial sustainability assessments across three states.
- Pollution Prevention at Food Focused Businesses within DuPage & Kane Counties. Another collaboration with EnergySense Resilience Center, this project is providing free technical assistance to 10 small for and/or non-profit entities, such as restaurants, grocers, and other food-focused businesses and organizations in DuPage and Kane Counties. By getting assessed, businesses can lower operational costs, reduce wasted food & resources, and attract environmentally conscious customers.
