Late May and early- to mid-June is the time of year to celebrate high school and college graduations as well as dads, grandpas, and father figures of all sorts as Father’s Day approaches (celebrated on June 15 in 2025). As you contemplate gifts for the dads and grads in your life, the following resources will help you make choices that are more “environmentally friendly,” in terms of reducing exposure to hazardous substances and promoting sustainable behavior. As always, please note that ISTC does not endorse, either explicitly or implicitly, any manufacturer, vendor, product, or service. Mentions of specific products or businesses below are provided for informational reference only.

Pots and pans

If the dad or grad you’re celebrating likes to cook or needs some kitchen supplies for their first apartment, you can reduce their exposure to PFAS by gifting them with stainless steel, cast iron, glass, or ceramic cookware.

Per- and polyfluoroalkyl substances, known as PFAS and sometimes called “forever chemicals” because they break down slowly and persist in the environment, are found in a wide variety of consumer products, including cookware treated with “non-stick” coatings. According to the U.S. EPA, these substances are found in the blood of humans and other animals worldwide and are present at low levels in a variety of food products and the environment. This is a concern since exposure may be linked to harmful health effects and there’s still a lot that we don’t know about their impact on human and environmental health, how much total PFAS people are exposed to, and how to effectively remove PFAS from the environment.

To help you evaluate options, check out Grace Kelly’s recent article for Serious Eats in which she tests several different cast iron skillets to find the best one: “To Find the Best Cast Iron Skillets, I Seared Steaks, Baked Cornbread, and Fried Eggs.” If you don’t want to dive deeply, Kelly summarizes: “The best cast iron skillet is from Lodge. It heats up fast and sears deeply, and only costs around $20. We also like the lightweight Lancaster No. 8 skillet, which is easy on the wrists and cooks food beautifully.” She also points out that cast iron cookware is tough, so in addition to using it in the kitchen, you can also use it on the grill or over a fire pit. This is another bonus if your dad or grad loves to cook out or camp out.

Similarly, Amanda Arnold vetted stainless steel cookware sets for a March 26, 2025 article for Forbes, highlighting her top 5 picks. Her pick for best-overall set was the All-Clad D3 Stainless 10-piece cookware set, while her pick for the best budget set was Cuisinart Chef’s Classic Stainless Steel 10-piece cookware set.

If you’re considering glass bakeware/storage, keep in mind that some brands like Pyrex and Anchor Hocking are now using tempered glass (heat-treated soda-lime glass) for items made in the U.S. instead of the borosilicate glass that they once used. This is important because borosilicate glass is much more resistant to large temperature shifts—like taking a made-ahead casserole out of the fridge or freezer and popping it straight into a hot oven—than tempered glass. Swift movement across these kinds of temperature extremes is sometimes referred to as “thermal shock.” So, even if you remember your grandma moving her Pyrex containers back and forth between hot and cold environments with confidence, modern dishes might shatter when exposed to thermal shock. Pyrex made with borosilicate (older items or modern items made outside the U.S.) tend to feature the brand name in all caps (PYREX) while tempered glass versions feature the name in lowercase letters (pyrex). It’s all good—just something to be aware of. For more info, see “The Actual Difference Between PYREX and pyrex” by Sheela Prakash (for Simply Recipes, 12/9/24) and “If Pyrex Isn’t Safe Anymore, Which Brand of Glass Bakeware Should You Buy?” written—appropriately—by Meghan Glass (for Allrecipes, 3/11/23), who points out that some brands like Oxo are still consistently made of borosilicate glass. (Note that the headline for Glass’s article is somewhat misleading; tempered glass is safe so long as you’re aware that it’s not as resistant to “thermal shock” as borosilicate glass.)

Ceramic cookware is becoming popular as a PFAS-free alternative to traditional non-stick cookware. To help select ceramic pots and pans, see Nicole Papantoniou’s 2/19/25 article for Good Housekeeping, “6 Best Ceramic Cookware Sets, According to Expert Testing.”

If your gift recipient relies on their microwave instead of cooking elaborate meals, it’s still important to have glass or ceramic vessels for heating foods up, because research has shown that even FDA-approved plastics release microplastics into your food when they’re heated in a microwave.

Local foods

Continuing the subject of cooking, your dad or grad might appreciate a gift that provides them with locally grown or raised foods. Everybody eats, after all! According to the USDA National Institute of Food and Agriculture (NIFA), “there is no consensus on a definition of “local” or “local food systems” in terms of the geographic distance between production and consumption. Nevertheless, local and regional foods are increasingly being recognized as an important component to efforts to create more sustainable, resilient, healthier, and equitable food systems…Findings are mixed on the impact of local food systems on local economic development and better nutrition levels among consumers, and sparse literature is so far inconclusive about whether localization reduces energy use or greenhouse gas emissions. Notwithstanding, consumer demand for locally produced food is increasing and creating jobs and opportunity throughout rural America for farms, businesses, and entrepreneurs that store, process, market and distribute food locally and regionally.” In any event, consuming food produced locally gives you the opportunity to know the farmers involved and to ask questions about their practices (e.g., whether and which pesticides are used, how livestock are treated, if they employ any conservation practices on their land, etc.). That’s not something you can do at your typical supermarket.

A Community Supported Agriculture (CSA) subscription could be a great option for dads or those grads moving into new apartments who have access to reliable transportation. CSA is a type of arrangement in which a farmer offers “shares” of their harvest to the public in the area surrounding their farm. Individuals buy those shares (sometimes called a “subscription” or “membership”) before, or at the very beginning of the growing season, helping the farmer with cash flow and giving them some guaranteed income, which is important since the size of their total harvest is impacted by the weather and other factors beyond their control. Subscribers then receive fresh local produce (or meat, eggs, or other items, depending on the farm involved) at regular intervals throughout the season. This typically involves the subscriber picking up a box, bag, or basket of items on a set schedule on the farm or some other public location. The Local Harvest website can help you find a CSA in your dad or grad’s area and elaborates on the benefits for both farmer and subscriber, as well as variations and the shared risks (e.g., if the farmer’s crop is destroyed by a natural disaster, you’re not likely to receive a refund if you don’t receive your normal boxes of goods).

Young grads going off to college dorms may not want or need the amount of local food a CSA provides, but they can still benefit from gifts centered on local foods. Consider a gift card or membership for a local food co-op store so they can stock their mini fridge–the Local Harvest website also lets you search for co-op stores near a given location. Another idea would be to give them some money, reusable cotton or canvas shopping bags, and perhaps a bus pass, along with directions and other information for farmers markets where they’ll be living. The Local Harvest website lets you search for farmers markets in a given area, and if you grad will be in IL, check out the Illinois Farmers Market Association (ILFMA) website and use the MarketMaker map to find farmers markets and other food-focused businesses throughout the state.

Safer personal care products

You might be considering the gift of personal care products for your dad or grad—maybe a nice aftershave or fragrance, hair styling products, shaving cream, moisturizer, etc. But you may have heard news related to health impacts of various chemicals that might be present in such products and aren’t even sure you remember the names of some of the substances, let alone how to avoid them. Explore the Environmental Working Group (EWG) Skin Deep database to find a variety of products that have been evaluated based on their ingredients, scientific and industry literature related to those ingredients, intended use, areas of the body to which the products are exposed, the type of exposure, target demographics, and other factors. Products are scored based on the best available information on known and suspected hazards, and the database is updated regularly to reflect advances in scientific research.

The database includes 9 product categories: makeup; nails; face & body; oral care; hair; fragrance; babies & kids; men (which overlaps with some of the other categories but includes items marketed mainly toward men, such as beard oil, shaving creams, and men’s fragrance); and sun (for products like sunscreen, sunless tanning, and even lip balms or moisturizers with SPF ratings). You look at lists for subcategories to find information on specific products, or search the database for specific ingredients, product types, or brand names. If you pull up a list on a specific type of product (e.g. shaving cream), you can click on each listed item to learn more about its score, its ingredients, and when its entry was last updated. You can also sort the list alphabetically (a to z or vice versa), by best to worst score, or by worst to best score. Product entries will also display an evaluation of the data availability on which the rating is based (e.g. limited or fair).

Better bouquets: Sustainable purchasing and end-of-life management for floral arrangements

UI Public Affairs: L. Brian Stauffer. © Board of Trustees of the University of Illinois.

As Valentine’s Day approaches, purchases of flowers increase. Whether for a holiday gift, special occasion, or other celebration, most of us will buy bouquets or flower arrangements at some point. But have you considered sustainable options or the best way to manage bouquets after they fade?

Note that links to products, programs, or vendors below are for informational purposes only and should not be construed as endorsements by ISTC, the Prairie Research Institute, or the University of Illinois Urbana-Champaign.

Why it matters

When you think about the economic impacts of agriculture, you’re likely to consider crops used to feed humans or other animals. But floriculture is also “big business.” The USDA defines floriculture as “that branch of horticulture dealing with the production of field-grown or greenhouse-grown plants for their flowers or showy leaves.” According to the US Department of Agriculture National Agricultural Statistics Service (USDA NASS), in 2023 (the year with the most recently published data), floriculture sales in IL totaled $134,063,000. For the same year, the Society of American Florists, reports total spending nationwide on floral products (flowers, seeds, and potted plants) was $72.8 billion.

While the USDA NASS estimates there are approximately 263 commercial floriculture operations, throughout IL alone, most of the flowers purchased in the US are imported from other countries. Utah State University Extension notes that “As many as 80% of all cut flowers sold in the U.S. are imported, with the majority coming from Columbia, Ecuador, Holland, and African countries such as Kenya that have the climate for the year-round cut flower cultivation (Cain, 2022; Knoch, 2022; Li et al., 2016; Tegethoff, 2023).” (See Utah State University Extension site for full citations.)

Source: https://www.ers.usda.gov/data-products/charts-of-note/chart-detail?chartId=106472

Clearly, buying and selling flowers has a huge impact on carbon emissions just from the perspective of product distribution. Imported blooms are flown thousands of miles and once they reach US soil, they might still end up being trucked for many more miles before reaching a retail location. Beyond the fuel used for transportation, refrigeration is often required along the way to keep blooms fresh.

Like any other agricultural operation, floriculture involves the use of a lot of resources (e.g. land, water, labor, etc.) and the application of a variety of chemicals that may have negative impacts on human and environmental health. A recent review of pesticides in flower production identified 201 different compounds used, 93 of which are banned by the European Union (Pereira et al., 2021).

So, although we tend to focus on aesthetics when picking the flowers we buy, attending to any available information on the source and production practices matters greatly if we care about environmental sustainability. It’s also worth considering the impacts of any packaging involved, which might be destined for the landfill if it can’t be reused, recycled, or composted. Because of the resource use embodied in them, it pays to consider keeping ornamental flowers and plants vibrant and in use for as long as possible, and when they are genuinely wilted and no longer lovely, we should try to keep them out of landfills if possible through composting. When plant material and wasted food (collectively called “organics”) break down in landfills without oxygen present (i.e., in anaerobic conditions), methane, a greenhouse gas is produced. The US EPA reports that municipal solid waste landfills are the third largest source of human-related methane emissions in the US, accounting for approximately 14% of methane emissions in 2022.

Better options

So how can you reduce the negative impacts of the flowers you buy?

Buy locally grown flowers whenever possible. If purchasing at a florist, grocery store, or large retail outlet, look for posted information on the source of the product or ask staff for more information. Depending on your location, time of year, and the intended use for your flowers, you may be able to get what you need from a farmer’s market or directly from a farm. This gives you the opportunity to meet the grower and ask questions about their operation. Buying local also supports the local economy and populations of pollinators, depending on the amount of shelter used in production (i.e. open fields, greenhouses, etc.). And of course, you’ll greatly reduce the greenhouse gas emissions involved in distribution. According to the Association of Specialty Cut Flower Growers (ASCFG), local flowers also tend to be of a wider variety, will last longer because they’ve traveled a shorter distance to you, and may smell better, because they are less likely to have been bred for uniformity, a practice that may compromise natural fragrance. If you don’t already have a farmer’s market or other favorite source for local flowers, the following resources will help you find them:

  • ASCFG Find Local Flowers and Growers Map: https://localflowers.org/find-flowers/. Enter your location and choose a radius in miles for your search.
  • IL Specialty Growers Association Live Local Shop Local Map: https://www.specialtygrowers.org/shoplocal.html. There are a few different ways to search. Either select “Floriculture” from the “Products” drop-down menu OR “Cut Flowers” from the “Product Attribute” drop-down menu OR type “flowers” or “cut flowers” into the search bar.

If you can’t find locally grown, look for sustainably grown options. This might mean using an online service that sources sustainably grown flowers or looking for certified products in shops. Links related to certification programs below will allow you to dive into the details of the program standards if you wish.

  • ReVased: https://www.revased.com/. This company began in 2019 with a focus on “upcycling” flowers from events (more on that below), selling a portion and donating a portion of these reclaimed arrangements. When the COVID-19 pandemic caused events to temporarily be put on hold, they shifted gears and now primarily offer online orders of sustainably grown flowers and plants. From their website: ‘We are proud to source our flowers from high-quality, sustainable-minded farms in both the U.S. and South America. The flower farms we work with have achieved Rainforest Alliance Certification, Fairtrade Certification, or take other steps for environmental, economic, and social sustainability. This includes protecting forests and natural wildlife habitats; promoting farmers’ human rights and safe, decent working conditions; conserving water and soil; and helping to lessen the burden of the climate crisis. We are lucky to work with amazing farm partners who meet these rigorous standards of excellence! We also ship “farm-direct.” This eco-friendly shipping method reduces carbon emissions by bypassing many stops in the traditional floral supply chain and reducing the total number of stems being cut, as every cut stem is meant for a customer! Additionally, we offset emissions from our shipments to neutralize our shipping footprint and make our shipments carbon neutral.’
  • Rainforest Alliance Certification: https://www.rainforest-alliance.org/insights/rainforest-alliance-certified-ferns-flowers/. The Rainforest Alliance certifies products that comply with their agricultural standard which “protects ecosystems and wildlife habitats, conserves water and soil, promotes decent and safe working conditions, and ensures that farms are good neighbors to rural communities and wildlands.” According to the Alliance’s website, Costco stores in IL sell their certified flowers, plants, coffee, and tea.
  • Fair Trade Certification: https://www.fairtradecertified.org/what-we-do/what-we-certify/floral/. Fair Trade certified products comply with standards to safeguard working environments and conditions, living wages and benefits, and to eliminate poverty and forced labor. Check the packaging on products or signage at your florist or other retailer for an emblem from Fair Trade USA or Fair Trade International. According to the Fair Trade USA website, you can find certified flowers at Sam’s Club and Whole Foods.
  • Veriflora Sustainably Grown: https://www.scsglobalservices.com/services/veriflora-certified-sustainably-grown. “This third-party certification assures buyers and consumers that cut flowers and potted plants have been produced in an environmentally and socially responsible way, with practices that achieve the highest level of product quality.” This is part of the SCS Global Services suite of third-party certifications, so look for an emblem with the SCS green hummingbird logo and the words “Sustainably Grown Certified.” Veriflora products are available through various florists and supermarkets, so check with your local shops.
  • Organic:  While it is possible to find flowers with USDA Organic certification, this tends to be used for edible flowers or those used for tea. Many growers will follow organic principles without going through the formal certification process, which is why buying local is great if feasible, because it allows you ask questions and learn more about the production process.
  • The Bouqs Co.: https://bouqs.com/about-us/our-difference. This online retailer sources directly from farms that use sustainable practices.

Reuse and other diversion options

If you’ve bought flowers for an event, when your festivities are done, there’s no reason to send those blooms to the landfill. Explore donation of arrangements that still look lovely, and composting when those flowers have truly faded.

  • ReVased: https://www.revased.com/pages/non-profit-floral-directory. As noted above, this company started out by rescuing flowers from events to rehome them. Since the pandemic their focus is more on online sales, but they have started directory of non-profit organization that can accept donated flowers. Currently, all the IL entries are in the greater Chicago area/northern IL. You can also reach out to them at hi@revased.com for assistance in finding organizations to accept floral donation, but bear in mind their capacity for this is currently limited.
  • Repeat Roses: https://repeatroses.com/. This company works nationwide and will be hands-on, collecting flowers after an event and delivering them to organizations to which they’re being donated. Where commercial composting facilities exist, they can also pick up donated flowers once they’re truly withered and deliver them to the composting facility. According to their website, “Some locations will offer only limited composting sites within reasonable driving distances. For those locations, we will explore alternatives to ensure we divert flowers from landfills.” In order to have this level of service, you’ll need to plan far in advance. “Four to six months is ideal to secure your date to ensure you are on our pickup schedule. The earlier you decide to reserve your date on the calendar, the more time we have to coordinate with your florist and venue. Often, it is easier for your florist to know of your plans to donate your flowers in advance so they can design your arrangements with this information in mind as it relates to vase/container rentals and arrangement structure. Additional fees may apply to events booked with limited notice.”
  • Reach out directly to local organizations that may accept donated flowers. If you are planning an event that includes flowers, reach out in advance to local women’s shelters, nursing homes, hospitals, senior services, or cancer support non-profits to see if they could reuse your blooms and work with them, friends, or family on transportation of donations.
  • Compost. Check the Illinois Food Scrap and Composting Coalition (IFSCC) website list of commercial compost haulers and processors or for tips on composting at home if you’ve got the space and the interest and you’re dealing with a bouquet or two rather than lots of flowers from an event.
  • Preserve your blooms. If your flowers have sentimental value, consider preserving them. Check out HGTV’s guidance on various methods for drying, pressing, or using resin to create keepsakes.

Composting pumpkins and other ways to green your Halloween

Photo by Colton Sturgeon on Unsplash

Did you know that IL leads the nation in the production of pumpkins? You may not realize it, but pumpkins are mostly water! A great deal of labor, land, water, and other resources are invested in growing, harvesting, distributing, and processing pumpkins in our state, so if you care about conserving resources, it’s scary to think about how many pumpkins end up in landfills once Halloween has passed.

After the neighborhood kids have finished collecting their treats, some folks leave their pumpkins out for squirrels and other wildlife to feed on. Others may have a backyard compost pile for returning jack-o-lanterns to the soil. If you’re not lucky enough to have the space or time to create your own compost, many cities and towns throughout IL host collection events in early November for composting decorative pumpkins. Such an event is called a “Pumpkin Smash.” Some collections may involve fun activities in which people can literally “smash” their pumpkins by throwing them into a designated dumpster or compost heap. SCARCE and the cities of Wheaton and Elmhurst hosted the state’s first pumpkin collections in 2014, diverting over 9.31 tons of pumpkins from landfills and helping to improve composting laws in Illinois. By 2023, Pumpkin Smashes were being held at over 95 sites in IL and beyond, and in that year over 241 tons of pumpkins were composted!

If you’re interested in coordinating a Pumpkin Smash in your community, SCARCE has just released an updated how-to guide for pumpkin collections, available for free on their website. The revised guide includes tips for on-site composting at community gardens and small farms. This option is great for areas of the state without access to a commercial compost processing site that will accept food scraps.

The main Pumpkin Smash page on the SCARCE site provides other resources including diversion statistics from last year, downloadable promotional materials to help spread the word about your local event, a link to register your Pumpkin Smash site, and a map to help you find Smashes in your area. Visit https://www.scarce.org/pumpkins/ and keep scrolling to find these resources. Note that there are two “official” dates for Pumpkin Smashes this year–Saturday, November 2, and Saturday, November 9.

Scientists study how a diabetes drug affects soils

The transport of pharmaceuticals released from sewage treatment plants into farmland soils, with the potential to load into drinking water sources, is one that researchers at the Illinois Sustainable Technology Center (ISTC) study carefully. Even at low concentrations, medications can affect water ecosystems and soil health.

“Applying sewage waste to crop fields is a win-win practice because it provides nutrients and organic matter to the soil and prevents waste sludge from ending up in landfills,” said Wei Zheng, ISTC environmental chemist. “The issue is that wastewater treatment plants cannot remove emerging contaminants and pharmaceuticals. We cannot ignore the potential risks from this practice.”

Biosolids, which are treated sewage sludge, are a product of the wastewater treatment process. Biosolids can be used on farmland to improve soil fertility, Zheng said.

In a recent study, Zheng and colleagues investigated the adsorption of sitagliptin in soils treated with sewage wastewater. Sitagliptin is commonly used to treat diabetes and is frequently detected in sewage effluent and the environment because it does not fully degrade during the wastewater treatment process. Lagoon-based sewage treatment systems in rural areas also remove fewer contaminants than typical municipal wastewater treatment facilities, so contaminant concentrations in sewage are higher.

Sitagliptin concentrations in the environment are unregulated in the United States. The drug is considered an emerging contaminant for its potential risk to the public. 

Study findings showed that biosolids, which have a large amount of organic matter, bonded with the medication in soils and reduced its adsorption. Results also showed that increasing the amount of sewage effluent used for soil amendment reduces the adsorption of sitagliptin in soils.

Metformin is often prescribed, sometimes with sitagliptin, to treat diabetes. As part of this study, the researchers examined how this medication affects the uptake of sitagliptin in soils. Metformin is more water soluble, more degradable, and has less adsorption in soils than sitagliptin. 

They found that increasing metformin concentrations in sewage effluent reduced the interaction of sitagliptin with the soil surface. This means that multiple pharmaceuticals and personal care products (PPCPs) in sewage can compete in soils, reducing the adsorption capacities of individual products.

“Some states have regulations for contaminants, such as per- and polyfluoroalkyl substances (PFAS), which are considered ‘forever chemicals’, in biosolids and sewage effluent, so over certain levels, biosolids cannot be used for soil amendments,” Zheng said. “In Illinois, there are no regulations, so it’s highly possible that organic chemical contaminants released from biosolids will leach to drinking water supplies, especially in rural areas. It is important to study and explore ways to minimize the leaching and runoff of PPCPs.”

The results of this study can be used to predict how other PPCPs are transported and adsorbed on agricultural soils and develop management strategies to reduce the risks of using sewage wastes in rural areas.

The U.S. Department of Agriculture funded the project. An article, “Influence of Biosolids and Sewage Effluent Application on Sitagliptin Soil Sorption,” was published in the journal Science of the Total Environment. Zheng is also working on a project supported by the U.S. Environmental Protection Agency to monitor PPCPs in sewage effluent and develop mitigation strategies to protect the environment and drinking water quality.

Illinois Farm to Food Bank Feasibility Study report now available online

Cover page of Farm to Food Bank report

As reported in previous posts, the Illinois Sustainable Technology Center Technical Assistance Program (TAP) has been collaborating with Feeding Illinois, the Illinois Farm Bureau, the Illinois Specialty Growers Association, and other stakeholders to explore ways to reduce food waste from farms while also recovering nutritious fresh foods to increase the state’s food supply and help citizens facing food insecurity.

Recently, project partners released the initial feasibility study report from the first year of this project, entitled Exploring the Development of an Illinois Farm to Food Bank Program. The report is available in IDEALS, the University of Illinois’ institutional repository.

Through interviews, surveys, focus groups, and pilot projects it became clear that a Farm to Food Bank program would be welcomed by both the farming and food banking communities in Illinois. Such programs are defined in the Code of Federal Regulations [at 7 CFR 251.10(j)] as “the harvesting, processing, packaging, or transportation of unharvested, unprocessed, or unpackaged commodities donated by agricultural producers, processors, or distributors for use by Emergency Feeding Organizations (EFOs)” – i.e., hunger relief agencies. Several such programs exist throughout the United States, though not in every state (for examples, see the “Lessons from Other Farm to Food Bank Programs” section of this report). While commonly referred to as Farm to Food Bank, these programs can also operate as Farm to Food Pantry programs.

While this is an ongoing research project, this report serves to demonstrate research efforts undertaken from December 2020 – February 2022 that have led to this conclusion along with identifying strengths, weaknesses, threats, opportunities, and recommendations for a statewide Farm to Food Bank program.

Recommendations for 2022 and beyond include the following:

Three essential aspects of a farm to food bank program1. A Farm to Food Bank program should have three primary goals:
➢ Support farmers by providing a secondary market for off-grade and  surplus products.
➢ Increase access to local, nutritious foods.
➢ Reduce food waste/surplus on farms and associated energy and resources.

2. Equity must be an essential part of the program.
3. Seek out partnerships with existing aggregation and processing centers.
4. Seek out partnerships with new food pantries.
5. Make Feeding Illinois and their member food banks a staple at ag-focused and food access events.
6. Increase communication between food banks.
7. Ensure buy-in from food banks and food pantries.
8. Improve capacity and resources at the food pantries.
9. Connect a Farm to Food Bank program with existing
technology platforms.
10. Diversify funding sources. Develop an advocacy plan to pursue public and private support.
11. Establish an advisory board to guide the actions of the Farm to Food Bank program.
12. Develop guidance and educational programs for farmers.
13. Measure success by more than just pounds of donated food.
14. Hire a dedicated employee to manage the Farm to Food Bank program.
15. Adapt the program as needed.
16. Continue piloting Farm to Food Bank strategies around the state.

While these recommendations can serve to guide Farm to Food Bank efforts, further research is needed to uncover opportunities and test collection and distribution strategies. ISTC and Feeding Illinois will collaborate to continue this research for the remainder of 2022 into 2023. The project team will continue outreach and engagement efforts to both increase participation and gather feedback on the program. They will also continue to work with Rendleman Orchards, which participated in the first pilot project of the study, as well as conducting additional pilot projects. In the coming year, ISTC and Feeding Illinois will also work with farmers markets around the state to test aggregation strategies.

Read more about this project on the “Project Descriptions” section of the TAP website.

Scientists study ways to reduce PPCPs transferred from soils to food plants

Plant growing in soil

The debate continues: how much risk to human health is the transfer of pharmaceuticals and personal care products (PPCPs) through soils to food plants when biosolids, sewage effluents, and animal wastes are applied to fields? As scientists speculate and study the factors that affect risk, researchers at the Illinois Sustainable Technology Center (ISTC) are finding innovative solutions to remove PPCPs before they contaminate the vegetables and fruits we consume.

PPCPs are the chemicals that make up fragrances, cosmetics, over-the-counter drugs, and veterinary medicines. These chemical residues in the environments are considered emerging contaminants because they are not yet regulated by state and federal agencies.

Organic wastes like biosolids, sewage effluent, and animal waste contain PPCP residues. When these are applied to farm fields, some of the chemicals may degrade, while others may transfer from soils to roots of vegetables and fruits, and then possibly accumulate in edible plant tissues.

Field studies have shown that pharmaceutical concentrations in soils were lower than predicted because PPCPs may degrade in soils, latch on to soil particles, or run off/leach into surface and groundwater. Yet continued and long-term application of PPCP-containing biosolids, animal wastes, and wastewater effluents may increase their concentration levels in plants, according to Wei Zheng, ISTC scientist.

“There has been much argument and debate if PPCPs derived from organic waste application in crop fields can cause risks on public health,” Zheng said. “This issue will become even more at the forefront as the use of biosolids and sewage effluents in crop production systems increases. More studies are necessary because PPCPs vary in their toxicity and physicochemical properties in the environment. In particular, the compounds that are highly persistent and toxic will be a concern.”

Zheng reviewed the literature, summarized the research findings, and made recommendations for future research in a recent article published in Current Pollution Reports.

Factors affecting PPCP transfer

In his review, Zheng reiterated that the factors that have the greatest effect on PPCP transfer are the properties of the PPCPs and soils as well as plant species. Plants grown in sandy soils have higher levels of PPCPs than those grown in high organic matter and clay soils. For certain PPCPs that are destroyed in soils, the process breaks down the original compound into metabolites that may be more toxic and mobile. Metabolites with lower molecular weights could be taken up by plant roots more readily.

Studies have also found that leafy vegetables, such as lettuce and cabbage, tend to have a higher potential to take in PPCPs than root vegetables. Furthermore, certain chemicals accumulate in the roots and have little effect on human health, while others can be transferred to leaves. Further research is needed to develop thresholds for accumulations of PPCPs in food crops when biosolids, effluents, and animal manure are used on fields.

Mitigation efforts

At ISTC, Wei and colleagues are studying several technologies to remove PPCPs, either before they reach the soils or after sewage waste application. The study is being supported by a project funded by the U.S. Department of Agriculture (USDA).

In the project, Wei is studying the feasibility of using inexpensive oils to capture hydrophobic PPCPs from wastewater effluents. The treatment, which would be used at water treatment plants, is especially low cost when applying used cooking oils, such as those from restaurants.

One advantage of this process is that oils remove PPCPs from rural sewage water while leaving behind the nutrients that fertilize crops. After capturing PPCPs, the spent oils can be used as fuel for diesel engines. The process can eliminate the captured contaminants.

Carbon-rich biochar produced from forest and agricultural residues can be used as a filter to absorb PPCPs from sewage water.  Biochar can also be directly applied to soils.

Studies found that the average PPCP concentrations in lettuce leaves decreased by 23 to 55 percent when biochar was used in the soil compared with the soils without biochar. Biochar can also be composted with solid waste to immobilize PPCPs and reduce their transfer in soil-plant systems.

In the USDA project, scientists will conduct laboratory, field, and numerical modeling studies to better understand the transfer of PPCPs to crops when rural sewage effluents are applied to agricultural lands. The results will help federal and state agencies and farmers evaluate their current nutrient management and nontraditional water-use practices, inform science-based regulatory programs, and suggest best management strategies to minimize risks and promote the safe and beneficial use of nontraditional water in agriculture.

This fall, the Illinois Farm to Food Bank program wrapped up its pilot project with Rendleman and Flamm Orchards in Union County. Nearly 375,000 pounds of peaches and nectarines were distributed to food banks throughout Illinois.

Michelle Sirles of Rendleman Orchards said, “The Farmer to Food Bank Pilot was a HUGE Success. Every single person we worked with went above and beyond to make this a successful pilot year. It could not have come at a better time with the over abundance of peaches nationwide. It prevents a lot of peach dumping. It recouped farmers costs while providing fresh and healthy food for those in need. As a farmer we felt completely supported by Illinois Farm Bureau, our politicians, our state university, and our food bank partners. I truly feel this could be a shining star program for our state.”

The program also connected Roth Countryside Produce, located in Tazewell County, with a Peoria Area Food Bank agency to purchase $1750 worth of sweet corn, green cabbage, red cabbage, green beans, cantaloupe, bell peppers, green zucchini, golden zucchini, and seedless cucumbers.

Keep up to date with the program through the Farm to Food Bank Feasibility Study newsletter. If you’re a grower who wants to participate in the project, contact TAP.

US EPA releases report on environmental impacts of US food waste

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.

Farmers show interest in Farm to Food Bank Program

While thousands of Illinoisans go hungry every day, up to 40 percent of food goes uneaten. The Illinois Sustainable Technology Center (ISTC), Feeding Illinois, and other organizations are partnering to explore new, viable ways to connect farmers directly with food banks to increase the state’s food supply for the food insecure and reduce waste.

The Farm to Food Bank program partners are conducting a feasibility study for a statewide program, identifying approaches to address barriers, evaluating logistical challenges, and uncovering locally appropriate strategies. The result will be a roadmap used to roll out a state-funded program in Illinois, according to Zach Samaras, ISTC technical assistance engineer.

Besides ISTC and Feeding Illinois, study collaborators include the Illinois Farm Bureau and the Illinois Specialty Growers Association. In the first year, the team has conducted a farmer survey, started a pilot project, and visited the eight state food banks.

Farmer survey

One of the first actions was to create and distribute a statewide survey to farmers. Questions pertained to the type of product that farmers produce, their marketing strategies, barriers to production, and food losses. Slightly less than 10 percent of survey participants responded. The next step is survey analysis.

Farmers are also being recruited for focus groups to be held at an agricultural conference in early winter. This will be an opportunity for the collaborators to gauge farmers’ interest in the possibility of participating in a Farm to Food Bank program and collect further information on factors that would make participation more feasible for producers. Those interested in participating in focus groups should contact ISTC at info-istc@illinois.edu.

Pilot project

In the first pilot project, which started this summer, Rendleman Orchards in Alto Pass donated grade 2 peaches to a food bank in southern Illinois. Grade 2 produce is typically small or has slight blemishes.

The organizations are looking to find an optimal mixture of incentives for farmers to participate in the program. In this case, the farm receives a tax deduction for the donated produce and reimbursement from Feeding Illinois and the food banks for the “pick and pack” costs.

The pilot project quickly scaled up from two pallets of peaches transported to one food bank in southern Illinois to over 40 pallets sent to four food banks in various parts of the state.

“While we are very happy with the numbers, our biggest goal was to build relationships between the farmers and the food banks and develop a process that could work for a variety of farms across the state,” said Samaras. “We certainly feel like we are on the right track.”

Farmer feedback

Since the program began, farmers have been receptive to learning more about the opportunity, said Steve Ericson, executive director of Feeding Illinois. Actual participation has been more challenging because once the growing, harvest, and marketing seasons begin, farmers find it too disruptive to start or change plans already in place. Also, it is important not to interfere with existing relationships farmers have with food pantries, which are distribution centers that receive food from food banks.

“The primary thing we’ve learned in this first year is that this is a learning year, Ericson said. “The interest is definitely there. In general and by nature, farmers are community-oriented. ‘Helping others’ is in their DNA. We want this program to provide a meaningful way for them to do that as a group and individually.”

A major future challenge will be determining the logistics of transporting a certain volume of produce efficiently from the farm to food banks. The growing season for specialty crops in Illinois is only six months long, a time when farmers are consumed with work at the farm. Another barrier is that Illinois’ specialty crop farms are for the most part smaller and more widespread than those in other renowned produce states.

Convincing farmers that it is worthwhile to build business relationships with food banks versus contributing locally will take time to instill and to prove the benefits, Ericson said.

The Farm to Food Bank program is supported by the USDA through The Emergency Food Assistance Program. For more information, visit the Farm to Food Bank Program website.

Farm to Food Bank Survey Deadline Extended, Focus Groups Planned

Graphic encouraging IL farmers to complete an online survey by March 30, 2021

In a previous post, we described a collaborative feasibility study being conducted by ISTC’s Technical Assistance Program (TAP), Feeding Illinois, the Illinois Specialty Growers Association, and the Illinois Farm Bureau, to collect information on locations, types, and quantities of surplus food in Illinois. Through a producer survey, a series of focus groups, and implementation of pilots across the state, the team looks to uncover the optimal mix of incentives and program interventions to overcome the current barriers to efficient flows of fresh food produced in Illinois, to Illinois residents, with as little waste as possible. The goal is to identify opportunities to develop a statewide farm to food bank program that will address food insecurity and food waste.

To help with this effort, farmers from every region of Illinois are encouraged to complete an online survey at go.illinois.edu/farm2foodbanksurvey. The survey will remain open (responses accepted) until a target number of responses have been received to ensure a robust sample size. The survey takes approximately 10 minutes to complete.

Participants are also being recruited for a series of virtual focus groups. The focus groups will be crafted to gather input from all regions of the state, as well as perspectives from underserved farmers. Participants will include producers, representatives of hunger relief agencies, and food distributors. Input from focus groups will supplement, validate, and contextualize the information gathered through the survey. This will also provide TAP the opportunity to gauge feasibility, interest, and barriers to implementing and participating in a farm to food bank project among producers.

The online producer survey offers respondents the opportunity to indicate their interest in focus group participation. Individuals can also contact the ISTC Technical Assistance Program to indicate interest in the focus groups, for additional information on the study, or for assistance with completion of the producer survey.
