Part 3 of 3 in ILSR's Reducing Contamination in Composting Webinar Series.<\/h3>\r\nContamination is a major challenge for composting at all scales, often requiring significant investments of labor, time, and money to manage. In this webinar, researchers and programs shared how they are measuring contamination. <\/span>Whether you're launching a new program or refining an existing one, this webinar offered actionable strategies for using data to drive results.<\/span>\r\n

This live webinar took place on June 12th, 2025<\/b><\/h2>\r\n

Ver la grabaci\u00f3n<\/a><\/h4>\r\nLearn how Hutchinson, Minnesota, is reducing compost contamination by combining rigorous measurement with creative, community-driven outreach. Cassandra Meuffels (Outreach Coordinator, City of Hutchinson) and Mimi Shah (Principal, Amplify for Change) shared insights from <\/span>Compost It Right!<\/span><\/i><\/a>, a comprehensive education campaign that uses clear messaging, citywide materials, and strong partnerships to boost participation and reduce contamination in curbside organics collection. The session covered how Hutchinson tracks progress using cart tagging, waste audits, and inbound load assessments \u2014 and how these data inform campaign adjustments. They also shared how events, community outreach, local business engagement, and a \u201cthree strikes\u201d system reinforce behavior change across the community.<\/span>\r\n\r\nCaroline Barry, Program Manager at Closed Loop Partners\u2019 Center for the Circular Economy, presented on contamination research and analysis conducted at 10 diverse US composting sites. She discussed how to do a waste characterization study, measurement considerations for feedstock, overs, and finished compost (including manual waste sorts and lab tests), the results from their research, and an overview of associated costs.\r\n\r\nCaroline\u2019s presentation was followed by a presentation by Dr. Fred Michel, a professor of Biosystems Engineering at The Ohio State University (OSU). <\/span>He focused on using lab tests and bioassays to identify contaminants as well as shared recent research findings from year one of a two-year project testing for the presence and concentrations of persistent herbicides as well as other contaminants such as PFAs.<\/span>\r\n\r\nA moderated Q&A session followed the presentations.\u00a0<\/span>\r\n
