We know how to compost. But how do we build and sustain the systems, relationships, and knowledge needed to make composting successful?

In this October 8, 2026, Compost Conversations webinar, the Composting Association of Vermont (CAV) welcomes James McSweeney, author of Community-Scale Composting Systems, founder of Compost Technical Services, and creator of the 131° School of Composting.

Drawing on nearly two decades of experience, James reflects on his journey from the Highfields Center for Composting to his work supporting composters across the country. Along the way, he explores how Vermont's composting landscape has evolved, what makes technical assistance effective, and why building a thriving composting ecosystem requires much more than knowing how to manage a compost pile.

While we have a strong understanding of the technical aspects of composting, the greater challenge is often creating the conditions that allow composting operations and programs to succeed. Education, mentorship, technical assistance, supportive policies, and community relationships all play essential roles in turning composting knowledge into lasting practice. Topics include:

• The evolution of composting in Vermont and the legacy of the Highfields Center for Composting

• The complementary roles of education, technical assistance, mentorship, and collaboration

• The challenges of building a career in compost technical assistance and training

• What it takes to create a supportive ecosystem for community-scale composting

• Emerging challenges, including contamination, industry consolidation, and economic uncertainty

• Inspiring examples of community composting in Arizona, Detroit, and Rhode Island

• Why relationships, shared knowledge, and local engagement are essential to producing clean, high-quality compost

The conversation also explores a deeper question: Why do we compost? Beyond waste reduction, James reflects on composting as a way to care for the earth, support healthy communities, and reconnect with the living systems that sustain us.
