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.

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.

US EPA releases report on environmental impacts of US food waste

EPA infographic 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.

Graphic representation of the study elements, as described in the text of the blog post

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.

Technical Assistance Program collaborates to connect surplus food with hunger relief agencies

The University of Illinois, Feeding Illinois, the Illinois Specialty Growers Association, and the Illinois Farm Bureau are collaborating to collect and collate information on the locations, types, and quantities of “surplus” specialty crops in Illinois, including potential acquisition costs. 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.

Wasted Food = Wasted Resources + Wasted Dollars + Wasted Nutrition

According to the second edition of the Natural Resources Defense Council report Wasted: How America is Losing up to 40 Percent of Its Food From Farm to Fork to Landfill, roughly two-fifths of the food we produce in our country goes uneaten for a variety of reasons, based on losses in the production, processing, distribution, and consumption stages of our food system. Beyond the food itself, this reality represents a huge loss of the resources invested in our nation’s food production–“food and agriculture consume up to 16 percent of US energy, almost half of all US land and account for 67 percent of the nation’s freshwater use.”

Image of NRDC "Wasted" report cover with a photo of a watermelon with a wedge removed.The loss is economic as well as environmental. NRDC estimates that over 400 pounds of food are wasted per person annually in the US, equivalent to “a loss of up to $218 billion each year, costing a household of four an average of $1,800 annually.”

The situation is made all the more tragic when considering that Feeding America estimated 14.3 million American households were food insecure with limited or uncertain access to enough food in 2018. “Food insecurity” refers to a lack of access to enough food for an active, healthy life for all household members and limited or uncertain availability of nutritionally adequate foods.

In 2018, 1,283,550 people experienced food insecurity in Illinois.

Global Pandemic Makes a Bad Situation Worse

During the COVID-19 pandemic, the issues of food waste and hunger have become even more pronounced. In the wake of unemployment, medical bills and other unforeseen costs, many people have struggled to make ends meet. Simultaneously, our food supply chain scrambled to pivot to a world in which institutions and businesses involved with food service or food retail shut down as part of efforts to slow the spread of disease. As an example of the challenges this presented, some perishable goods like milk or meat may be produced and packaged in bulk specifically for large-scale customers such as restaurants. So, when those customers suddenly no longer exert their typical demands on the system, large quantities of commodities may spoil if new customers can’t be identified to absorb the available supply, or if the means for alternative packaging or distribution cannot be quickly realized. News reports featured stories of commodities without outlets being dumped or livestock euthanized and record-long lines at food banks. Feeding America estimates that due to the effects of the coronavirus pandemic, more than 50 million people may experience food insecurity, including a potential 17 million children.

Farm to Food Bank Programs as Viable Solutions

Decreasing waste and increasing nutritional access are being addressed across the nation in various ways. One strategy for addressing these issues simultaneously is through Farm to Food Bank programs. “Farm to Food Bank” projects 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. Some existed long before pandemic-related restrictions rocked the nation’s food systems, since it is not uncommon for farmers to donate their surpluses to local hunger relief agencies. Existing programs have had to work hard to keep up with increased demand during the pandemic and expand where possible. Several new farm to food bank programs have been created over the past year in direct response to pandemic-related systemic pressures, as highlighted in a recent article for Civil Eats by Lynne Curry. Many of these are notable because they use donated funds to pay farmers fair market prices for commodities that would otherwise be wasted, or to cover other economic barriers to surplus redistribution (e.g. labor or transportation costs), creating interim markets as a stopgap response to disruptions caused by the pandemic.

One such program, The Farmlink Project, was launched in April 2020 by college students in response to the struggling they witnessed in their home communities after returning from their shut-down campuses. The project uses donated funds to pay for the packing of farm surplus and delivery to food distribution sites. Databases of interested farmers and nearby food banks are being built to enable efficient connections. Partnership with Food Finders, a food rescue organization, and Uber Freight allows logistical hurdles to be addressed by those with appropriate expertise. In the organization’s short life it has grown to involve more than 100 college and university students from across the country, serving all but five of the fifty United States, and has delivered over 22,000,000 pounds of food, according to the project website.

In New Mexico, the American Friends Service Committee (AFSC), a Quaker organization, began its Farm to Food Bank Project at the start of the pandemic, and reported in December 2020 that it had provided “more than 12,000 pounds of local, fresh produce–reaching thousands of community members in need.” AFSC uses donations to purchase “organic produce from 25 sustainable farms and distribute that food to Roadrunner Food Bank—the state’s largest food bank—as well as five shelters and food pantries that serve people who are homeless, domestic violence survivors, seniors, and immigrants.” They additionally supply “farmers with seeds and other farming materials, as well as safety items like face masks and gloves. In return, farms are providing a portion of the food they grow to local relief agencies.”

Some long-running programs have integrated various ways to address economic barriers for farmers. Operating since 2005, the California Association of Food Banks (CAFB) Farm to Family program offers a “pick and pack” fee to farmers to help mitigate harvesting and packaging costs. CAFB handles the logistics, transporting surplus food from farms to food banks throughout the state for redistribution. Participating farmers are also eligible for a 15% state tax credit.

With these and many other examples elsewhere in the nation, various stakeholders in Illinois are considering what lessons can be learned to determine how the farm to food bank concept could be applied to circumstances within our state.

Stakeholders Collaborate to Improve Food Security in Illinois

Even before the pandemic began, Illinois stakeholders were considering how to ensure more food would reach those in need through farm to food bank strategies. In early 2020, staff from Feeding Illinois and the Illinois Farm Bureau began discussions related to expansion of programs and opportunities for moving surplus food commodities to hunger relief agencies throughout the state. These agencies reached out to the Illinois Sustainable Technology Center (ISTC) Technical Assistance Program (TAP) to discuss the types of data and analyses needed to support such efforts. Plans began for a feasibility study, involving collaboration with the Illinois Specialty Growers Association, to expand and improve farm to food bank commodity flows. The study kicked off with a survey of participants at the annual Illinois Specialty Crops Conference in January 2021.

The overall outcomes of this project are being realized by meaningful collaboration between over two dozen organizations across Illinois. The feasibility study is being led by Feeding Illinois with support from the University of Illinois-Urbana Champaign, the Illinois Farm Bureau, and the Illinois Specialty Growers Association. ISTC’s TAP is spearheading data collection and analysis, as well as final report preparation.

Project Objectives

The feasibility study will involve collection and collation of information on the locations, types, and quantities of “surplus” specialty crops in Illinois, including potential acquisition costs. Objectives include:

  • Provide producers with additional end markets for commodities
  • Identify the quantity and quality of surplus food in Illinois
  • Expand supply of fresh food to food banks
  • Increase food security
  • Reduce food loss and foster a statewide circular economy
  • Establish a sustainable farm to food bank program in Illinois

Study Components

In order to evaluate and devise effective strategies for expansion of farm to food bank programs within Illinois, the study team is evaluating what has worked as part of such programs in other states. Project staff are reviewing and reaching out to similar programs nationwide to compile best practices, key challenges, pinch points where material flows may slow down or stop due to a variety of factors, performance indicators, and key stakeholders to include in strategic planning.

Graphic representation of the study elements, as described in the text of the blog post

Simultaneously, the project team is taking a three-pronged approach to compile the data necessary to develop and assess the feasibility of strategies for a statewide farm to food bank program in Illinois.

Graphic representation of the three data compilation elements, as described in the post textThe first step is collecting feedback from Illinois producers on current conditions, challenges, opportunities, and past experiences via the aforementioned online survey, which was launched during a session presented at the virtual 2021 Illinois Specialty Crop Conference that took place in January. Conference attendees were encouraged to complete the survey during the conference and will receive electronic reminders from session coordinators. It includes questions on current practices, market channels, market alternatives, product marketability, and the farm-to-food-banks experience from the producer perspective. The survey will be open to Illinois producers until March 15th.

Additionally, virtual focus groups including producers, representatives of hunger relief agencies, and food distributors will be held, to supplement, validate, and contextualize the information gathered through the surveys. 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.

Survey respondents and focus group participants will have the opportunity to indicate interest in participating in future pilot studies of any new farm-to-food-bank strategies to address food insecurity identified as part of this overall feasibility study.

Finally, TAP will synthesize the findings from the surveys and focus groups to estimate the statewide supply of food commodities not currently entering the market. TAP will prepare a final report–essentially a roadmap for a statewide farm to food bank program–outlining the opportunity and feasibility (including both logistical and economic considerations) of implementing various farm to food bank project scenarios. The report will be made available online to inform Illinois producers and other stakeholders, and to assist with similar efforts in other states.

Participate

Illinois producers can support these efforts by completing our survey. It takes approximately 10 minutes to complete. If you prefer,  request to have a a hard copy of the survey mailed to you by contacting ISTC’s Technical Assistance Program.

For additional information, assistance with survey completion, or to express interest in participating in the forthcoming focus groups, please contact the ISTC Technical Assistance Program.

Rural-urban collaboration yields alternative solutions to improve state water quality

The Metropolitan Water Reclamation District of Greater Chicago has published a story about their water quality projects in Fulton County. ISTC researcher Wei Zheng is one of the researchers involved in this collaborative effort.

From the article:

In addition to deploying new nutrient recovery technology, the MWRD voluntarily established a program at its Fulton County site to foster collaboration with the agricultural sector to develop and expedite nutrient reduction practices in non-point source areas.

The 13,500-acre property, located in Fulton County between Canton and Cuba, Illinois, was originally purchased in 1970 to restore strip-mined land and approximately 4,000 acres were converted to productive farmland. Years later it became the ideal site to use some of the farm fields to develop and test best management practices to reduce non-point source nutrients.

Since 2015, research and demonstration projects have been established at the site in collaboration with many partners such as the University of Illinois at Urbana-Champaign (UIUC) Crop Science Department, UIUC Department of Agricultural and Biological Engineering, Illinois Sustainable Technology Center, Illinois Central College, Ecosystem Exchange, IFB, and Fulton County Farm Bureau. The projects established include inter-seeded cover cropping, riparian grass buffer, denitrifying bioreactors, runoff irrigation, subirrigation, drainage water managements, designer biochar, and watershed-scale nutrient reduction demonstration.

Read more about Dr. Zheng’s research on the ISTC website.

New project uses biochar to absorb excess nutrients from tile drainage

In a new $1 million three-year project, Illinois Sustainable Technology Center (ISTC) researchers will develop a bioreactor and biochar-sorption-channel treatment system to remove excess nitrogen and phosphorus from tile drainage water, which will reduce nutrient loss from crop fields to local waterways.

Excess nutrients in surface water contribute to harmful algal blooms that produce toxins and threaten the health of water ecosystems. A variety of treatment techniques have been studied to reduce nutrient losses.

Woodchip bioreactors, which are buried trenches, have proven to be a cost-effective and sustainable solution to reduce nitrate-nitrogen loss from tile-drained crop fields. However, concentrations of ammonium-nitrogen are often elevated after water has flowed through a bioreactor. Also, woodchip bioreactors do not have a significant effect on phosphorus removal.

Principal investigator Wei Zheng and colleagues plan to develop an innovative treatment system by integrating woodchip bioreactor and designer biochar treatment techniques to reduce the losses of both nitrogen and phosphorus nutrients from tile drainage.

Designer biochars are applied in biochar-sorption-channels to capture dissolved phosphorus and ammonium-nitrogen simultaneously. Researchers will seek to produce the most efficient designer biochars by pyrolysis of biomass pretreated with lime sludge.

The U.S. Environmental Protection Agency-funded project will evaluate the new system by conducting a scale-up field study at a commercial corn production farm.

Researchers will also apply the nutrient-captured biochars as a soil amendment and a slow-release fertilizer in fields to improve soil fertility.

The results from this project will help federal and state agencies and farmers evaluate their current nutrient management practices, inform science-based regulatory programs, and offer an innovative, feasible, and cost-effective practice to mitigate the excess nutrient loads to watersheds, prevent and control algal blooms, and improve agricultural sustainability.
