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.

What is Pollution Prevention?

US EPA Waste Management Hierarchy including pollution prevention

September is a time to think about pollution prevention, aka P2, because the third week of September every year is celebrated as Pollution Prevention (P2) Week in the U.S. In 2023, P2 Week will be September 18-22. As you mark your calendar, you may ask yourself—what exactly is pollution prevention, and how can I contribute to the effort?

First, let’s take a moment to consider what pollution itself is. The U.S. Environmental Protection Agency (EPA) defines pollution as “any substances in water, soil, or air that degrade the natural quality of the environment, offend the senses of sight, taste, or smell, or cause a health hazard. The usefulness of the natural resource is usually impaired by the presence of pollutants and contaminants.” So, pollution is the contamination of the environment by potentially harmful substances. If you think of a polluted environment as analogous to a human body with harmful chemicals in it or disease, then it’s easy to think of pollution prevention as analogous to disease prevention. You’ve probably heard the old quote from Benjamin Franklin, “An ounce of prevention is worth a pound of cure.” Although Franklin was talking about the prevention of house fires, in modern times, the phrase has come to be used in the sense of health care. It means that taking preventative measures (e.g., exercising, watching what you eat, getting enough sleep, etc.) is a much more sensible strategy to take, wherever possible, than waiting until disease sets in and then working to treat it. It’s far better to avoid a problem than to have to try to solve the problem afterward.

Thus, pollution prevention is the sensible strategy of preventing the release of harmful substances into the environment, aka source reduction, to avoid the negative impacts of pollution and the cost, time, energy, and other resources that would otherwise need to be expended on environmental clean-up after the fact. Or, as the U.S. EPA states, pollution prevention is “actively identifying equipment, processes, and activities which generate excessive wastes or use toxic chemicals and then making substitutions, alterations, or product improvements.” P2, or source reduction, “is fundamentally different and, where feasible, more desirable than recycling, treatment or disposal. It is often more cost effective to prevent pollution from being created at its source than to pay for control, treatment and disposal of waste products.  When less pollution is created, there are fewer impacts to human health and the environment.”

P2 practices for manufacturing and industrial sectors might entail using less toxic cleaners, less hazardous ingredients or process inputs, conserving energy and water, and reducing waste through the reuse of materials such as drums or pallets. Manufacturers and supporting industries in Illinois can also contact the Illinois Sustainable Technology Center (ISTC ) Technical Assistance Program (TAP) to learn more about U.S. EPA-funded P2 assistance available free of charge to members of the aerospace, automotive, chemical, food and beverage, and metal manufacturing and fabrication sectors.

The principles of P2 can be applied to any sector or effort and in homes and schools. It’s all about more efficient use of valuable resources, such as energy and water, using less-toxic materials and products, and avoiding the generation of waste so you don’t have to deal with as many disposal considerations. So, if you practice waste reduction by eliminating disposable products and single-use plastics, if you purchase and use energy-efficient appliances and weatherize your home for the winter, if you look for and fix leaky pipes or faucets, or if you use safer cleaners, you’re practicing P2!
