We believe that composting is vital to the health of all ecosystems on Earth.

Our Why

Our mission is to make the sustained production of high-quality compost available to all composters for the well-being of our planet and all the life it provides.

Offering tools that are always free and always accessible supports this mission.

Our Truth

The source of truth for our tools is The Composting Handbook – the definitive guide to the latest science, principles and best practices for composting for farm and large-scale commercial composting operations.

We always welcome new research and data, become a subject matter contributor.
