    Contamination is a major challenge for composting at all scales, often requiring significant investments of labor, time, and money to manage. This webinar series offers a deep dive into three aspects of contamination and composting, including on-site management, outreach and education, and measurement.

    This webinar series, together with our broader library of composting-related webinar recordings, is one way ILSR supports the growth of a distributed and diverse composting infrastructure that includes community-scale and on-farm systems.
