Composting

What's so important about compost?

Food waste is a pressing environmental concern in Illinois. In Cook County — and in many counties around the state — it accounts for up to 37% of landfill material. But food waste is not just filling up municipal dump sites. It is a major source of methane, a greenhouse gas considerably more harmful to the climate than carbon dioxide (CO2). By diverting organic waste materials from landfills and recycling it into compost we protect our environment by reducing the amount of greenhouse gas released into the air. Composting can reduce food waste in landfills and transform it into a valuable resource, just as recycling has reduced and transformed plastic, paper, and aluminum waste in the past 50 years. This will only happen if we all understand the impact of food waste in landfills and have opportunities to compost our organic waste.

Learn what was discussed at the 2023 Compost Summit

On Friday May 12, 2023 Illinois Extension convened compost professionals from the Greater Chicagoland region to discuss how to build a culture of composting.

A full report will be available Fall 2023.

2023 Compost Summit Summary

You can help change our compost culture.

By learning more about composting, seeking opportunities to recycle your food scraps into compost, and telling others about what you learned you will play an important role in increasing the demand for and the rate of composting adoption to reach a “tipping point” where composting is as common as recycling. Together we can build a culture of composting to create a healthy environment, promote local circular economies, support our urban farms and gardens, and meet the EPA’s goal of cutting food waste in half by 2030. Read more about our project Building a Culture of Composting in Greater Chicagoland for which we received an Extension Foundation NTAE Expansion award for 2022-23.

Demonstration

See composting in action at our research and demonstration farm in Matteson IL and at our Lake County office beginning Fall 2023.

Our collective efforts will...

lead to a future in which everyone views compost as a valuable resource, separates their compostable waste, and has access to a composting service. In this future, greenhouse gas emissions have decreased, global warming has slowed, and more urban farmers are using high-quality, locally produced compost to grow healthy food for our residents.

Illinois Extension in Cook, Lake, and McHenry Counties is committed to educating residents on the how and why of composting so the future we imagine becomes reality.
