    A webinar sharing education and outreach strategies to reduce contamination at composting sites.

    Contamination is a major challenge for composting at all scales, often requiring significant investments of labor, time, and money to manage. To paraphrase Einstein, the smart person solves a problem, but the genius avoids it.

    Watch the recording of this webinar to hear how innovative education and outreach strategies targeted at program participants – including social marketing campaigns to impact behavior – can reduce contamination issues at the source. If you’re involved in an existing composting initiative or interested in supporting composting in your community, this webinar is for you.

    This live webinar took place on April 2, 2025.
