The 2022 Statewide Materials Characterization Study identifying and quantifying materials being landfilled in Iowa is now available

Waterloo, IOWA – According to the state officials, the study will be the basis for implementing new and updated programs and policies and enhancing existing efforts to further reduce and recycle end of life materials.

Iowa DNR reportedly contracted with consulting firm SCS Engineers to conduct the study. 

Early data analysis shows that overall paper, organics and plastics were the most landfilled material categories, by weight. 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 program and policy decisions, to expand waste diversion initiatives, improve existing program efficiencies, and identify public awareness needs. 

The study will also help the DNR measure progress in obtaining waste reduction and recycling goals.
