2022 Statewide Materials Characterization Study

The Iowa Department of Natural Resources 2022 Statewide Materials Characterization Study is now available. Food waste was, by far, the most landfilled material component, followed by plastic film (including plastic shopping bags), cardboard, textiles, and compostable paper. Over 70 percent of the landfilled materials are considered reusable, recyclable or compostable.

The department and local governments will use the data to make programs and policy decisions, to expand waste diversion initiatives, improve existing program efficiencies, and identify public awareness needs.
