We are a new online platform for advancing composting across the nation and globe. Our mission is to build a regenerative, inclusive and equitable food system through the act of composting.

The 131° School of Composting is the educational branch of Compost Technical Services, a consulting practice founded by James McSweeney (author of Community-Scale Composting Systems). 

We are inviting Composters of all skill levels and sizes to join us in learning the fundamental science and practical art of compost making.

What's Coming

  • The 131° School’s Compost Operator Training

    Our first course offering will be a two-month online program focused on best practices for food scrap composting. The course is designed for any-size operation above the home-scale (commercial, on-farm, municipal, on-site), and is based on the Vermont Compost Operator Certification Training curriculum, which James has developed and taught since it’s inaugural offering in 2011.

  • Community of Practice

    A collaborative creation space where composters can develop business and systems concepts in solidarity with other socially and environmentally conscious practitioners.

  • Live discussions

    Meet some of the nation's most experienced compost facility operators.
