Treatment plants can effectively remove microplastics and per- and polyfluoroalkyl substances (PFAS) from wastewater before they’re discharged to lakes and rivers, but large amounts of contaminants end up in solid waste, called biosolids, often used on agricultural fields as soil nutrients. By land applying this material, these contaminants then are re-released back into the environment.  

In a recent study published in an Illinois Sustainable Technology Center report, John Scott, analytical chemist at ISTC in the University of Illinois, studied the fate of microplastics and PFAS as they moved from landfill leachate, or water that filters though the mound of trash, to wastewater treatment plants and beyond. As health concerns about PFAS in water continue to grow, Scott predicts that state and federal regulatory agencies will set rules limiting these contaminants in water.

“I expect regulations concerning PFAS will be coming soon, but the big question is that nobody knows where to set the limits because the toxicity of PFAS hasn’t been established yet,” Scott said.   

To date, wastewater treatment plants are not required to monitor for PFAS and microplastics, so studies on these contaminants provide a better understanding of their major sources and how they can end up in the environment.

Eighty percent of plastics are destined for landfills. Among the castaways are food packaging, furniture, clothing, and other textiles that shed microplastics and PFAS contaminants. Scott noted that while all samples contained both microplastics and PFAS, PFAS concentrations in landfill leachate were found to be much greater than in wastewater influent.  

After wastewater treatment, the highest levels of microplastics and PFAS were in the biosolids, of which 50% are applied back to the land. If farmers stop using biosolids in fields due to regulatory and liability issues, the only option is to send them to landfills where the cycle from landfill to wastewater treatment plant will continue.

“Once in landfills, the stuff moves into the leachate, which is headed back to the wastewater treatment plant,” Scott said. “We’re just moving them from one environmental compartment to the next without addressing the problem. We never get rid of them; we’re just shifting them back and forth.”

To manage this problem, which is increasing over time because plastics and PFAS take so long to break down, consumers have some responsibility, he said.

“People have the perception that when you throw something away and it goes to a landfill, then it’s gone forever, when it’s not,” Scott said. “A landfill is just a holding place, and actually, the contaminants will end up fugitive in our environment.”

If the use of PFAS is regulated, PFAS in raw sewage will decrease, but contamination in landfill leachate will continue to rise, Scott said. Similarly, as plastics are added to landfills, they breakdown to smaller sizes, increasing contamination levels in leachate. Over time, landfills will become an even more significant sources of these contaminants, as well as many others.

TAP helps Chicagoland organizations tackle food waste

In an ISTC pilot project, several small organizations in Chicago learned that there are better, feasible options for handling wasted food than throwing it away. Composting, for one, works well for businesses that have access to compost hauling services.

The ISTC Technical Assistance Program (TAP) helps businesses and industry find solutions to reduce waste and use sustainable technologies. For this project, TAP staff hoped to make a difference working with owners of small businesses in disadvantaged communities that lack resources and are often overlooked for funding, according to Zach Samaras, ISTC technical assistance engineer and project director. The project is part of the University of Illinois Extension program, Building a Culture of Composting in Greater Chicagoland.

The five businesses in the case study included the Abiding Love Food Pantry in Zion, IL; Casa Central, a Latino social services agency with a full kitchen on site, located in Humboldt Park; Food He.ro, a Latino-led culinary school and grocery store in the Little Village; Khepri Café, a café and kitchen in Albany Park; and Tom’s Place, a full-service breakfast and lunch restaurant in the Back of the Yards community.

After touring the businesses, Samaras and staff collected, sorted, and weighed two days-worth of waste and recycling to determine how much could be composted. Results showed that more than 60 percent of all material sorted could be handled this way. The waste audit illustrated the amount of waste each day that these businesses produce.

“Most business owners probably think that they don’t waste that much so showing them the data was really eye-opening for them,” Samaras said. “It helped people put into perspective that the amounts get pretty big, pretty fast. It also helped them to get on board, to understand the issue and what they can do about it.”

TAP provided funding for compost hauling services and staff gave individualized recommendations and helped set up compost bins and coordinated services. Some of the challenges to initiate composting and reduce waste by other means were physical space issues in tight kitchens and the importance of staff on different shifts communicating about prioritizing foods for future shifts so less food is wasted.

Samaras did find, though, that kitchen staff were receptive to suggestions. Besides composting, other waste-reduction measures were suggested, such as preventing food waste by highlighting food soon to expire, donating food, and recycling food scraps.

“It tends to be the case that people who work with food are conscious of food waste and want to do a better job, but they are busy folks,” Samaras said. “They don’t have time to be looking up storage techniques.”

One of the five businesses was unable to initiate a composting program because they are located outside of Chicago where there are few compost haulers to service the area. The other four businesses were interested and committed to continuing their program after the funding ends.

For more information, read the case study, Food Waste Technical Assistance for Small Businesses. The project was funded by an NTAE Extension Foundation Expansion Grant. ISTC’s TAP program helps to make companies and communities in Illinois more competitive and resilient.

Holiday gifts with sustainability in mind

Whichever winter holiday(s) you observe, odds are ‘tis the season for gift giving. Even if you don’t observe any of the major winter holidays, you’ll surely think about gifts at some point in the near future to celebrate a special occasion. If you’d like to align your gifts with sustainable values, the following ideas and resources might be helpful. Please note that links and companies mentioned in this post are for informational purposes only, and should not be construed as endorsements by ISTC, the Prairie Research Institute, or the University of Illinois.

Give an Experience

Many of us are fortunate enough to have plenty of “stuff” already, and if that’s the case for your intended recipient, consider an alternative to giving them more material goods. Experiences can often be more meaningful and personalized than physical gifts and presenting them can be an opportunity to start a conversation about consumption and its impacts on resource use, though one should not equate gifting experiences with avoiding consumption. Experiences still involve the use of material goods and consumption of resources; e.g., cooking someone their favorite dinner still requires the use of cookware, energy, and ingredients that themselves require natural resources to grow, raise, or manufacture. However, some gifted experiences may use items or resources that you or your recipient already own or would consume regardless of the special occasion. Continuing the previous example, you’re not likely to buy new pots or appliances to cook dinner, and since your recipient would need to eat anyway, there would always be impacts associated with the ingredients for the meal. Of course, other experiences may involve situations outside normal day-to-day circumstances that necessitate the use of resources (e.g., fuel for travel) we would not otherwise consume. Taking a spouse on a dream vacation or treating your best friend to a concert performance by their favorite band are examples. In such instances, it’s important to remember that giving an experience is less about avoiding resource use than shifting human attitudes and focus. The goal when gifting an experience is not to completely avoid consumption–we all consume resources as part of being alive. Rather, giving an experience shifts the focus away from material items as ends in themselves toward human interactions and the associated memories that will endure longer than most physical gifts possibly could. Memories are durable gifts! As a person who cares about sustainability, you can still try to incorporate responsible consumption into the equation if possible—perhaps by using local, sustainably harvested ingredients for the special dinner you’re preparing, buying carbon off-sets for the travel to that dream destination, or taking public transportation to the concert. The key is sharing or fostering experiences fulfills the human need for authentic connection rather than human desires for material goods, and reinforces the idea that relationships matter more than stuff. Valuing relationships between living things (in this case between people) is essential to thinking about ecosystems and the mindset that humans are a part of, rather than apart from, the rest of the natural world. Valuing relationships/connections can build a foundation for more sustainable behavior.

Give to Charity

Another option is to make a donation in honor of your loved one to a charitable organization that resonates with their interests and values. If you aren’t already aware of a specific group dear to their heart, you can search Charity Navigator at https://www.charitynavigator.org/ to find organizations by cause. The results display ratings, if Charity Navigator has adequate information to calculate one, based on “the cost-effectiveness and overall health of a charity’s programs, including measures of stability, efficiency, and sustainability.” You can filter the results by ratings, different aspects of performance (called “Beacons” on the site), state, organization size, and other factors. For example, I entered the term “sustainability” into the site’s search bar with the state filter “IL.” Charity Navigator also produces curated lists of charities, including “Where to Give Now,” “Popular Charities,” and “Best Charities.” As examples, check out the List of Best Women’s Charities, the “Where to Give Now” list for the Hawaii Wildfires, the List of Most Popular Charities. You can of course always enter keywords into Google or another search engine, but you might appreciate having Charity Navigator do some of the virtual “leg work” for you and having their expert analysis.

Note that your donation need not be monetary—you could donate your time or skills through volunteering. You might use your social media experience to help with promotion and online engagement for the literacy program for which your wife works, for example. You might even combine supporting a good cause important to your loved one with gifting an experience. For example, you might arrange to volunteer with an animal-loving friend at the local Humane Society shelter or pick up litter with your dad at his favorite nature preserve.

Give Gifts that Foster Reuse and Waste Reduction

Maybe you want to give your favorite waste reduction wonk items to help them get closer to the ideal of zero generation, but all you can think of are reusable coffee cups and cloth grocery bags which you know they already own. Here are some ideas and lists from which to draw inspiration.

Give Gifts that Reduce Dependence on Fossil Fuels

Friends don’t let friends rack up avoidable greenhouse gas emissions. Consult the following guides for some quick tips.

Give Gifts Free of PFAS

According to PFAS Central, a project of the Green Science Policy Institute, “PFAS, sometimes referred to as PFCs or highly fluorinated chemicals, are used in many consumer products and industrial applications because of their oil-, stain-, and water-repellent properties. Examples of chemicals in this class include PFOA, PFOS, and more than 3000 related compounds. The most studied of these substances is a chemical called PFOA, which is linked to kidney and testicular cancer, elevated cholesterol, decreased fertility, and thyroid problems and decreased immune response to vaccines in children. The most studied of these substances is a chemical called PFOA, which is linked to kidney and testicular cancer, elevated cholesterol, decreased fertility, and thyroid problems and decreased immune response to vaccines in children.” PFAS persist in the environment and pollute even the most remote places. Check out ISTC’s information and work on PFAS. This recent video from Bloomberg tells the fascinating story of how one woman uncovered how PFAS pollution became prevalent in her area.

So, these substances are clearly bad news for human and environmental health, but they’re in lots of consumer products—how can you help friends and family avoid exposure? Check out https://pfascentral.org/pfas-free-products/ for a list of PFAS-free outdoor gear, apparel, shoes, personal care products, baby gear, furniture, food ware, carpets and rugs, textiles, and home maintenance products.

ISTC provides food waste technical assistance to small businesses in Chicagoland

In the fall of 2022, University of Illinois Extension received funding from the Extension Foundation USDA-NIFA New Technologies in Ag Extension (NTAE) program for the expansion of its “Building a Culture of Composting in Greater Chicagoland” project. The goal was to divert food scraps and organic waste from landfills through educational efforts on the benefits of composting. Extension asked the Illinois Sustainable Technology Center’s Technical Assistance Program (TAP) to partner with them to provide food waste technical assistance to small businesses in the Chicagoland area.

TAP recruited five small businesses to receive assistance in communities overburdened by environmental issues and lacking resources. TAP’s zero waste team did an initial on-site assessment for each business, followed by a food waste audit. Then they prepared a report and worked with each company to help them implement recommendations. Participants were eligible for up to five months of funding to contract with a commercial compost hauling service.

The four companies that contracted with the commercial compost hauler said that they would continue paying for the service after the grant funding expired. The businesses also identified implementation challenges that they faced. These included lack of physical space in the kitchen, consistent communication between staff, and lack of a champion to lead their food waste reduction efforts.

Resources for Recycling Expanded Polystyrene

Photo by Caleb Lucas on Unsplash

Expanded polystyrene, or EPS, is a lightweight, closed-cell plastic foam used in a variety of products, including coolers, insulated beverage cups, takeout containers, building insulation, etc. This differs from extruded polystyrene (XPS), which is typically formed into rigid panels used for building insulation, mainly in terms of how it is manufactured, but also in terms of thermal protection, moisture resistance, and strength. Styrofoam is a brand name of XPS insulation manufactured by DuPont. Despite these differences, the similar products have become synonymous in the minds of most people, and just as certain brand names for facial tissue and bandages eventually became the common terms for those products, most people refer to EPS products as “Styrofoam.” In this blog post, when you read “EPS” or “expanded polystyrene,” know that this refers to the materials you likely think of as “Styrofoam” packaging–though DuPont would be quick to point out they’re not the same thing!

For several years, departments at the University of Illinois at Urbana-Champaign have been encouraged to recycle EPS at a drop-off location just outside the Dart Container plant in Urbana, IL. Recycling EPS is often not economically feasible basically because foam packaging is mostly air, and the fuel needed to ship large amounts of the bulky, lightweight material for processing would often not be offset by money obtained by selling it. Dart manufactures EPS products however, and thus, accepting and recycling it is in line with a sense of extended producer responsibility for the management of those products at their end-of-life, especially since EPS pollution famously takes hundreds of years to break down in the environment. The Urbana Dart plant used equipment to heat, extrude, and compress foam packaging into blocks of material that could be used for products such as picture frames, surfboards, or park benches. This YouTube video shows a similar operation in a California plant.

Earlier this year, however, Dart unfortunately announced that the Urbana plant would be closing by the end of 2023. While this is tragic mainly due to the loss of jobs and the potential blow to the local economy, it also means the loss of an outlet many people relied upon to keep EPS packaging out of the landfill. In fact, the City of Champaign ‘Where Do I Recycle It?’ resource reports that Dart closed their Styrofoam drop-off center in Urbana on Friday, September 29, 2023.

Obviously, the best approach, even before the sad news about Dart’s Urbana plant was announced, has always been to avoid EPS products whenever possible precisely because of the difficulties in recycling the material. But avoidance isn’t always possible for consumers, especially since EPS is so widely used in food and beverage packaging, to protect breakable products, and to regulate the temperature of various items during shipping—including items intended for laboratories. So, while alternatives are important to explore (and might be the subject of a future post), this post focuses on options that might help people in Champaign County divert EPS in the near term. Although the inspiration for this post is the change in opportunities to recycle EPS locally, many of the options below are applicable in other parts of the state or U.S.

Other foam drop-off sites (for those not in Champaign County)

To be clear, Dart is not going out of business or closing all its facilities, and the company does still offer public drop-off EPS collection points at various places in the U.S., including elsewhere in IL—just not in the Champaign-Urbana area anymore. To find out whether there’s a Dart public drop-off near you, visit https://www.dartcontainer.com/why-dart/sustainability/foam-recycling and search their map.

The Food Service Packaging Institute’s website includes a map showing EPS foam recycling drop-off sites throughout the U.S. and includes some basic information about foam recycling. See https://www.recyclefoam.org/about-foam-recycling to learn more and to search for a drop-off near you.

Dart’s Next Life Program

Besides their public drop-off collections, in April 2023 Dart also announced a mail-in product take back program called Next Life. This program is restricted to Dart brand products, but it is not restricted to EPS—Dart packaging made from paper (specifically from the Bare by Solo brand), polyethylene terephthalate (PET, #1), polypropylene (PP, #5) and expanded polystyrene (#6 foam) are all acceptable products. This program is not free, or particularly easy, however. To participate, consumers can visit https://take-back.dartcontainer.com/ and indicate which of these three packaging categories they’re interested in recycling. Then “proof of purchase” images must be uploaded, which might be in the form of scanned store receipts, invoices, or product photos. Once the images are uploaded, the consumer must then purchase a “discounted shipping label” by paying for flat rate shipping for the material ($9 for a maximum box size of 20″ x 30″ x 11” when the process was tested during the writing of this post). The purchased label can be printed out and used to ship the items back to Dart.

While this is better than nothing, the process is convoluted and inconvenient for consumers and is restricted to Dart products. Only die-hard individual environmental advocates, or organizations and businesses committed to zero waste, are likely to jump through the necessary hoops and pay to participate. Coupled with efforts to reduce relevant types of waste or avoid them altogether, this program can help keep some remaining unavoidable packaging out of landfills, so it’s worth keeping in mind.

Terracycle Zero Waste Box

If your organization or business generates a fair amount of EPS waste, you may wish to consider Terracycle’s “Styrofoam – Zero Waste Box™” as an option for recycling all sorts of EPS food packaging and shipping waste, so long as there is no food or other organics contamination on the foam. You buy a collection box with a pre-paid shipping label, seal it when full and send it back to Terracycle. This is very convenient but expensive—the box comes in three size options, with the smallest (11”x 11” x 20”)  costing $107. There are discounts for purchasing collection boxes in bulk (15+).

Packing Peanuts (Loose Fill)

EPS foam packing peanuts (aka loose fill packaging) were never accepted as part of Dart’s public recycling drop-off in Urbana. Local shipping businesses may accept them for reuse, however, as long as they’re clean and dry. It’s always advisable to call these companies first to confirm they will accept these before taking any to their location. The City of Champaign “Where Do I Recycle” page suggests contacting the UPS Store on Marketview Drive in Champaign, or CU Pack N Ship (formerly Mail & Parcel Plus). Note that the foam recycling map at https://www.recyclefoam.org/about-foam-recycling, mentioned above, can be searched specifically for loose fill recycling options.

Polystyrene Coolers

Many local laboratories, including those on the University of Urbana-Champaign campus, receive materials in polystyrene coolers. Laboratories should keep in mind that Millipore Sigma has a polystyrene cooler return program for U.S. customers, which is relatively easy and free for the consumer. See https://www.sigmaaldrich.com/US/en/services/support/recycling/polystyrene-cooler-return-program for details.

Several sources related to laboratory waste recycling suggest that New England Biolabs (NEB) have a similar polystyrene cooler take-back program, but that information seems to be out of date because NEB no longer uses EPS coolers. NEB now ships its products in an alternative to EPS, called the ClimaCell® cooler, created in conjunction with TemperPack, which is 100% recyclable. See https://www.neb.com/en-us/tools-and-resources/video-library/introducing-the-neb-climacell-cooler to learn more. If your laboratory or other business ships items that require temperature control, you might consider contacting TemperPack for options that suit your needs. See https://www.temperpack.com/climacell/.

Corning Packaging Take Back

Laboratories should also be aware that Corning will take back all Corning®, Falcon®, or Axygen® product packaging—including EPS centrifuge tube racks. Other acceptable wastes include pipette tip boxes and plastic bags and peelable lidding film paper from cell culture dishes, plates, and flasks, #2 or #4 only. See https://corning.mailthisback.com/ for further details and to print a pre-paid shipping label.

Other Mail-Back Options

Finally, the EPS Industry Alliance has a list of mail-back options at https://static1.squarespace.com/static/62e5bccd5d8f2e718d48d121/t/643ff95d6ef7d36ad9920d25/1686167676074/EPS+Mail+Back+Locations.pdf. There are eight locations in the Midwest region, though none are in IL.

Hopefully, these resources will help you divert unavoidable EPS from landfills. Are you aware of other EPS recycling programs? Share your knowledge with our zero waste team at istc-zerowaste@illinois.edu.

ISTC Sustainability Seminar speaker discusses equity, energy, and just transitions

On September 27, ISTC hosted a webinar featuring Benjamin Sovacool, Professor and Founding Director of the Boston University Institute for Global Sustainability and professor at the University of Sussex.

Searching for the Profit in Pollution Prevention: Case Studies in the Corporate Evaluation of Environmental Opportunities (U.S. EPA, 1998)
This research was initiated to more fully illuminate the challenges facing industry in the adoption of pollution prevention (P2) opportunities, and to identify issue areas that can be studied and addressed by policy-makers and industry. The case studies in this paper describe three P2 projects that were chosen/or analysis precisely because they were in some way unsuccessful. This analysis, based on a small and non-random sampling, is not necessarily representative of the experiences of all companies or all P2 investment possibilities.

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.

New law fosters farmers’ fresh produce donations to Illinois food banks

With Governor JB Pritzker’s signature on House Bill 2879, the Farm to Food Bank Program has been established in Illinois. The program helps farmers donate their surplus produce to local food banks and assists more than 1 million Illinoisans facing food insecurity. An ongoing three-year Illinois Sustainable Technology Center (ISTC) effort, which includes a feasibility study and pilot projects, has proven that the program can be successful in Illinois.

“This new law recognizes that we have a lot of residents facing hunger and a lot of surplus food on farms,” said Zach Samaras, ISTC technical assistance engineer and project director. “This program will support farmers with a secondary market, provide local, nutritious food to those in need, and reduce wasted food and wasted resources at the farm.”

The ISTC feasibility study began in 2020 when Feeding Illinois, the association of Feeding America food banks serving the state, commissioned ISTC to discover if the Farm to Food Bank Program is needed, wanted, and achievable in Illinois. ISTC staff visited eight food banks to learn about any existing relationships with local farmers and interviewed organization personnel that manage similar programs in 14 other states. In partnership with the Illinois Farm Bureau and the Illinois Specialty Growers Association, they also surveyed and conducted focus groups with Illinois farmers.

Over 60 percent of farmers surveyed were interested in finding new markets for some or all their commodities. The barriers to donating or selling food to food banks were primarily packing and labor expenses, storage, and transportation. 

In 2022, ISTC coordinated six pilot projects that resulted in donations of nearly 2.5 million pounds of produce that would have otherwise gone to waste, yielding nearly 990,000 meals. Feeding Illinois received a grant from the U.S. Department of Agriculture that provided $611,000 to reimburse farmers for some of their expenses incurred in donating produce. 

“We learned from our focus groups that farmers want to donate their surplus food, but that it should not be a burden on them financially to pick produce, package it, and deliver it to food banks,” Samaras said. “This program provides a safety net for farmers so they can grow a few extra acres for their primary markets, knowing that if they don’t sell everything, there is a program that can help them recoup some costs and make sure that the food is going to end up on someone’s plate.”

The newly signed law will invest $2 million to support already strained food banks and the farmers who donate food. The law also provides grants for capital improvements to transport and store food for underserved communities, which often lack the resources for residents to obtain fresh fruits and vegetables.
