What is Pollution Prevention?

US EPA Waste Management Hierarchy including pollution prevention
A version of the U.S. EPA Waste Management Hierarchy showing pollution prevention. See https://www.epa.gov/smm/sustainable-materials-management-non-hazardous-materials-and-waste-management-hierarchy for the more typical version.

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. See https://uofi.box.com/s/ypoep56408o4kk5pl0qpt2ojpwyo82qh and https://uofi.box.com/s/1crril27e0td9nd3j3njgh49mzoom0q5 for details.

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!

Use the following resources to learn more about P2 and how you can contribute to “preventative medicine” for environmental health and our collective human health which depends upon a healthy environment.

Celebrate Pollution Prevention Week, Sept. 19-25, 2022

The 2022 P2 Week Poster, designed by Rowan Lambert, a senior mural artist at the University of New Orleans.

The third week of September every year is celebrated as Pollution Prevention (P2) Week in the U.S. Thus in 2022, we focus particularly on pollution prevention from September 19th to the 25th, although P2 can and should be a priority year-round.

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.”

And did you know that 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….”

Helping businesses, organizations, institutions, and government agencies throughout Illinois and beyond to prevent pollution and use resources more efficiently to benefit our shared environment while also ensuring that companies and communities are more competitive and resilient is essentially the mission of the ISTC Technical Assistance Program (TAP). Our team is here to help your organization identify and implement ways to make your operations more sustainable and to prevent pollution. TAP is funded not only by the State of Illinois but also a variety of grants and fee-for-service projects for a variety of clients.

Currently, TAP has funding from the U.S. Environmental Protection Agency (EPA) to provide free sustainability assessments to Illinois manufacturers in the following sectors:

These assessments can help facilities reduce business costs, energy and water consumption, wastewater generation, emissions, and hazardous material usage, which can result in increased profitability, productivity, and competitiveness as well as recycling or diversion of by-products.

So if you are an Illinois manufacturer with facilities or supporting industries in those sectors, click on the link associated with your sector above to learn more about the assessment opportunity, and how TAP can help you identify P2 opportunities today. You can also access an overview flyer at https://uofi.box.com/s/fu0hsmj6skm52vl290nu7kiuohp758xa or contact Irene Zlevor via email or by phone at 217-300-8617. Additionally, a recorded webinar, presented to Sustain Rockford, describes the assessment process in detail.

New project uses flue gas and wastewater to make algae

A three-year, $2.5 million Illinois Sustainable Technology Center (ISTC) engineering-scale project will be one of the first and largest to combine carbon dioxide (CO2) from a coal-fired power plant with nutrients from wastewater treatment plants to cultivate algae for animal feeds. The project will demonstrate that producing algae for commodity animal products can be cost-effective and has added environmental benefits.

Algae has been used for decades in the niche markets of health and beauty. A more recent focus is its ability to use CO2 from coal-fired power plants to make biofuels and protein-rich food products.

Algae is fast-growing compared with traditional terrestrial feed crops, so it’s an attractive alternative for use in taking up CO2 from power plants because it requires less land, according to ISTC principal investigator Lance Schideman. Researchers will use the algae species Spirulina because it is already FDA approved for use as a food ingredient and has a high protein content, which commands higher prices.

The algae cultivation system will be integrated with the City Water, Light and Power plant in Springfield, Illinois. Schideman is collaborating with University of Illinois researchers Joshua McCann and Carl Parsons, who will conduct the animal feed studies. Global Algae Innovations will provide the algae biomass production system to be demonstrated at field scale for this project. The project is co-funded by the U.S. Department of Energy National Energy Technology Laboratory.

In the past, ISTC scientists have researched wastewater algae systems that are now used at 10 full-scale operating wastewater plants. They’ve also been a leader in recycling the byproducts of hydrothermal biofuel production to enhance algal biomass productivity. Global Algae Innovations is a leading designer and equipment supplier in the algae industry that has developed and demonstrated cost-effective, large-scale algae production systems.

“We’re putting all the pieces together in a coordinated fashion and lowering the net costs of growing algae using industrial and municipal by-products as inputs to improve the economic environmental sustainability of algal carbon capture,” Schideman said.

This approach reduces pollution and replaces the costly CO2 and nutrient inputs used in most algae cultivation systems. In the current commercial technology, managers buy liquid CO2 and various commercial fertilizers for the nutrient supply.

The wastewater, which is full of organic nutrients that support algae growth, will come from a local wastewater treatment plant.

“Using wastewater is a cost savings in the production process and it helps to solve problems that wastewater treatment plants are experiencing in trying to minimize nutrient discharges in the environment,” Schideman said. “In Illinois, the treatment plants are under increasing scrutiny, and regulations that are now voluntary are expected to become more stringent and potentially mandatory within the next decade.”

Ultimately, the system will produce feed especially for cattle and chickens. The product will be dry, which helps reduce spoilage, and will have a high nutritional value compared with some other feeds.

The typical price range for most bulk animal feed ingredients is $150–350 per ton, and certain high-value products can have a market value of $1,000–$2,000 per ton. Algae has the potential to command prices near the top of the range since some species contain highly nutritional components such as antioxidants and poly-unsaturated fatty acids. However, algal animal feeds are not yet established in the market, and the value of these products must be demonstrated through research studies like this one.

Schideman notes that the size of the animal feeds market is quite large and is a good match with the amount of CO2 produced by power plants around the country. Thus, using CO2 from flue gas in algae production has the potential to significantly reduce greenhouse gasses.

US EPA releases report on environmental impacts of US food waste

EPA infographic on environmental impacts of US food waste
Image from US EPA Office of Research and Development.

On November 30, 2021, the US Environmental Protection Agency (EPA) released a new report entitled “From Farm to Kitchen: The Environmental Impacts of U.S. Food Waste (Part 1).”

This report reveals the climate and environmental impacts of producing, processing, distributing, and retailing food that is ultimately wasted and projects the environmental benefits of meeting the US goal to prevent 50 percent of food waste by 2030. The report was prepared to inform domestic policymakers, researchers, and the public, and focuses primarily on five inputs to the US cradle-to-consumer food supply chain — agricultural land use, water use, application of pesticides and fertilizers, and energy use — plus one environmental impact — greenhouse gas emissions.

This report provides estimates of the environmental footprint of current levels of food loss and waste to assist stakeholders in clearly communicating the significance; decision-making among competing environmental priorities; and designing tailored reduction strategies that maximize environmental benefits. The report also identifies key knowledge gaps where new research could improve our understanding of US food loss and waste and help shape successful strategies to reduce its environmental impact.

The new report reveals that each year, the resources attributed to US food loss and waste are equivalent to:

  • 140 million acres agricultural land – an area the size of California and New York combined;
  • 5.9 trillion gallons blue water – equal to the annual water use of 50 million American homes;
  • 778 million pounds pesticides;
  • 14 billion pounds fertilizer – enough to grow all the plant-based foods produced each year in the United States for domestic consumption;
  • 664 billion kWh energy – enough to power more than 50 million US homes for a year; and
  • 170 million MTCO2e greenhouse gas emissions (excluding landfill emissions) – equal to the annual CO2 emissions of 42 coal-fired power plants

In short, significant resources go into growing, processing, packaging, storing, and distributing food. Thus, the most important action we can take to reduce the environmental impacts of uneaten food is to prevent that food from becoming waste in the first place.

A companion report, “The Environmental Impacts of U.S. Food Waste: Part 2,” will examine and compare the environmental impacts of a range of management pathways for food waste, such as landfilling, composting, and anaerobic digestion. EPA plans to complete and release this second report in Spring 2022. Together, these two reports will encompass the net environmental footprint of US food loss and waste.

Read the full report at https://www.epa.gov/system/files/documents/2021-11/from-farm-to-kitchen-the-environmental-impacts-of-u.s.-food-waste_508-tagged.pdf.  (PDF document, 113 pages)

Glass Recycling Foundation partners with Corona on glass recycling pilot project

Corona Protect Our Beaches and Glass Recycling Foundation logo

In a recent webinar hosted by the Illinois Recycling Association/Illinois Recycling Foundation (IRA/IRF), Scott Defife, President, Glass Packaging Institute and Glass Recycling Foundation (GRF), and Jeff Lang of Legacy Marketing described the Corona Protect Our Beaches program currently being deployed throughout Chicagoland.

According to GRF, more than 28 million glass bottles and jars end up in landfills each year, despite the fact that glass is endlessly recyclable. Recycling glass can protect the environment, economy, and sustainable manufacturing by capturing materials for reuse and keeping them out of landfills, as well as preventing litter from polluting the ocean and beaches.

To improve glass diversion from landfills and educate the public about the importance of glass recycling, Constellation Brands and its popular beer brand, Corona, have teamed up with GRF for a glass recycling initiative as part of the Corona Protect Our Beaches campaign.

This pilot program involves glass bottle recycling at Chicago-based bars and restaurants. Participating locations will separate their glass bottles into a separate bulk bin for pick up, starting in late June 2021. The GRF pays a hauler for the pick-ups; there is no cost to the participating locations. Any glass bottle, not just Corona-branded bottles, can be recycled, and no color sorting of bottles is required (as noted during the webinar Q&A).  Additionally, a small amount of incidental contamination (e.g. napkins or straws) is acceptable. This creates a simple system for the participating pilot locations.

The glass recycling pilot will be paired with special events including an interactive experience that sheds light on the need for glass recycling and helps “crush the problem.” At these events, empty bottles will be turned into a sand-like powder using a grinding machine that allows members of the public to watch the process, thus capturing their attention and imagination. Event attendees learn about the program and the call to action, “#DontTrashGlass.” Select consumers will be able to feed empty bottles into the grinding machine. Events will also feature a sand art station for attendees to enjoy as they learn about the benefits of recycling glass. According to Defife and Lang, the grinding machine is actually relatively quiet; the generators used to power the machine at these events is louder than the machine itself. The sand-like substance fits well with the theme of Corona’s Protect Our Beaches campaign and brand identity. GRF recognizes that there are many ways to use recycled glass and beach restoration is one of them; in addition, bottles can become new bottles, fiberglass, construction aggregate, sandblasting, and more.

Corona glass recycling event

Over the course of nine weeks this summer, the grinding machine will tour ten different wholesalers and corresponding accounts. The complete list of grinding events is available at https://protectbeaches.com/events/. Events kick off on June 25 at two locations in St. Charles, IL, and one in West Chicago.

During the webinar, it was noted that additional restaurants and bars can be added to the pilot in the Chicagoland area by contacting Defife or Lang (their email addresses are provided at the end of the webinar recording). Also, the collaborative team is trying to figure out what it would cost to continue the recycling program beyond the pilot period. A similar pilot is taking place in Phoenix, AZ, in partnership with Glass King. At the end of the pilot the total tonnage of glass recycled will be measured to illustrate diversion impacts. Participating locations will also learn valuable information about the nature of their waste streams from those measurements.

Solar-Powered Savings: Impacts of Net Zero Electricity at BEER NUTS

Packages of BEER NUTS
Image credit: BEER NUTS

BEER NUTS operates manufacturing, packaging, shipping, and office spaces in a multi-level, 100,000 square foot facility on a 16/4 schedule. It produces a variety of snack products and exclusively manufacturers its own products with a wide range of recipes. Products are distributed through various retail outlets and direct to consumers.

In fall of 2019, ISTC and their partners completed an Economy, Energy, and Environment (E3) assessment at BEER NUTS, a small, family-owned Illinois snack facility. At the company’s request, the assessment included the feasibility of on-site solar photovoltaics (PV).

The assessment revealed electricity savings opportunities that will reduce usage by 436,000 kWh annually. Once implemented, BEER NUTS’ electricity usage will drop to 342,000 kWh. Using this estimate and additional factors, the assessment partners proposed a 260 kW solar installation costing approximately $481,000. This array, projected to generate 342,370 kWh annually, would supply 100% of BEER NUTS electricity.

Despite the sizable upfront capital investment, the array could result in first-year cost of $94,820 through a reduced power bill and federal, state, and utility incentives. With continuing energy cost savings and incentives, BEER NUTS will break even at 2.5 years of ownership and will see a reduction of $149,000 in utility costs by the 5th year.

After implementing the proposed recommendations, BEER NUTS’ operations will be on target to achieve net zero electricity, meaning that the annual electricity delivered to this facility from the grid will be less than or equal to the renewable energy exported from this facility to the grid. It will also put them on the path to net zero energy. Finally, these recommendations will reduce BEER NUTS’ carbon emissions by 329.95 metric tons. This gives them a significant competitive advantage when working with retailers like Walmart, Kroger, and Amazon that have established sustainability benchmarks both for their own operations and for their suppliers.

This case study demonstrates that a small food manufacturer in central Illinois can replace its annual electricity usage with solar at a 2.5-year payback. Manufacturing facilities across Illinois can replicate these practices with similar benefits, regardless of sector, size, location, or familiarity with solar.
