We are a container for advancing composting and composters 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.
