Celebrate International Compost Awareness Week May 5-11, 2024

Poster for ICAW 2024, showing an illustration of a compost bin in an outdoor scene. The Earth is cradled among the compost in the bin and the bin is labelled "Nature's Climate Champion."

International Compost Awareness Week (ICAW) is celebrated annually during the first full week of May and is a time to learn more about composting organic wastes (e.g. landscape wastes and food scraps) as part of fostering healthier soil and reducing greenhouse gas (GHG) emissions. According to the U.S. Environmental Protection Agency (EPA), food waste is the “most common material sent to landfills nationwide, comprising 24.1 percent of municipal solid waste. When yard trimmings, wood and paper/paperboard are added to food, these organic materials comprise 51.4 percent of municipal solid waste in landfills.” Within landfills, organic materials decompose without the presence of oxygen (anaerobically), resulting in the generation of methane, which is a potent GHG. Reducing the generation of organic wastes and composting them when their generation can’t be avoided are important strategies for combating climate change. Hence the theme of this year’s ICAW: “COMPOST…Nature’s Climate Champion!”

According to the Compost Research & Education Foundation, this year’s theme highlights the role compost plays in fighting climate change. Besides reducing methane generation associated with landfilling organics, returning composted material to the soil ‘serves as a “carbon bank,” helping to store carbon thereby removing it from the atmosphere.’ Enriching soil with compost also reduces the use of synthetic fertilizers, thereby reducing the emissions associated with fertilizer manufacturing. Using compost can also increase our resilience to climate change impacts such as drought or extreme weather. For example, compost increases the capacity of soil to retain moisture, and compost makes soil more resistant to erosion by improving water infiltration, binding soil particles together, and slowing the flow of water through the soil. Thus, stormwater runoff is decreased.

For a list of in-person and virtual events to learn more about and celebrate composting, check out the Illinois Food Scrap & Composting Coalition (IFSCC) ICAW 2024 web page. New events are being added to the page daily, so check back often. If your organization is hosting a relevant event that you’d like to see promoted via IFSCC, submit information via this online form.

For information on getting started with home composting, check out the University of Illinois Extension Composting web pages. Extension also has great information on vermicomposting (using worms to process your organic waste), compost bins, troubleshooting, and answers to common questions.

For suggested children’s books related to composting and soil health, see the IFSCC’s curated list.

The IFSCC website also provides composting information for local governments and a recognition program for organizations and businesses that compost (on-site or via commercial composting services). You can also search for compost pick-up and processing services (available in limited areas of IL).

Happy composting!

ISTC is proud to be a 2024 Food Waste Prevention Week Partner

Proud to be a Food Waste Prevention Week Partner, April 1-7, 2024

Mark your calendars for Food Waste Prevention Week, scheduled to take place April 1-7 this year. 

In 2019 alone, EPA estimates that about 66 million tons of wasted food were generated in the food retail, food service, and residential sectors, and most of this waste (about 60%) was sent to landfills.  Food Waste Prevention Week is a collaborative effort to raise awareness about food waste and its negative impacts on our society and environment, while also sharing resources to help individuals, families, and organizations reduce their own food waste. Because its Technical Assistance Program (TAP) has experience working on food waste reduction and management projects, the Illinois Sustainable Technology Center is proud to be a partner organization for Food Waste Prevention Week for the second year in a row!

Be sure to check ISTC’s social media platforms during April 1-7, as we highlight some of the past and present work TAP is doing related to food waste, as well as facts and resources to help you on your food waste reduction journey. If you’re not already following us on social media, you can connect with us on:

ISTC will feature biochar research at Fulton County Field Day

ISTC’s Wei Zheng will showcase his research project “Designer Biochar to Capture and Recycle Phosphorous from Tile Drainage Systems” at the Illinois Farm Bureau’s Fulton County Field Day on July 16.

Zheng and team have proposed to combine a woodchip bioreactor with designer biochar at the tile drain outlet to capture phosphorus within the biochar. The biochar can be removed from the bioreactor system periodically and spread over the field as a form of slow release phosphorus fertilizer. They predict that the system will prevent excess nutrients from the phosphorus from entering local waterways and, if used throughout Illinois farmlands, will help reduce Illinois nutrient load to the Mississippi River and Gulf of Mexico.

Besides an inside look at Zheng’s research, the Field Day will feature additional research tours on vegetative buffer strips and drainage water recycling at the MWRD site, 15779 County Road 5, Cuba, IL. Registration starts at 11 a.m., followed by the tours from 12:30 to 2 p.m. Attendance is free, and lunch will be provided. Pre-registration is still available by calling the Fulton County Farm Bureau at 309-547-3011 or emailing at fultonfb@att.net.

ISTC receives grant to create biochars to reduce nutrient runoff from agricultural land

Midwestern farms use subsurface drainage to manage water on their fields.  The process uses perforated conduits to remove excess water from soil, which increases crop production and promotes soil conservation. However, these drainage systems can also transport large quantities of nutrients like nitrogen and phosphorus from agricultural fields to surrounding watersheds.

ISTC researchers Wei Zheng and BK Sharma have received a $414,380 grant from the Illinois Nutrient Research and Education Council to develop designer biochars that will capture and recycle phosphorus from tile drainage systems. The project will run from January 1, 2019 – February 28, 2023.

The objectives of this project are to:

  • create designer biochars to effectively adsorb phosphorus,
  • construct refillable biochar-sorption-channels to capture phosphorus from subsurface tile drainage, and
  • recycle phosphorus-captured biochars as a slow-released fertilizer.

The overall project goal is to develop a method that will minimize nutrient losses, keep phosphorus in the closed agricultural loop, and improve crop yields by enhancing nutrient use efficiency.

The research team will conduct laboratory experiments to produce designer biochars by pyrolysis of biomass pre-treated with lime sludge, evaluate their sorption capacities on phosphorus, and optimize their production conditions.

The team will also complete a field study to capture phosphorus losses from subsurface drainage systems via biochar-sorption-channels. The field study will be performed at the Metropolitan Water Reclamation District’s Nutrient Loss Reduction Research site in Fulton County. Furthermore, they will conduct a greenhouse experiment to use  phosphorus-captured biochars as a slow-released fertilizer to improve crop yields.

Finally, they will perform a cost-benefit analysis and compare their technique with other best management practices (BMPs) on phosphorus removal studied at the same field location.

The successful completion of this project will offer an innovative, feasible, and cost-effective method for enhancing nutrient utilization, which will increase crop production and protect water quality in the Midwest.
