As environmental engineers, scientists and educators, O2Compost’s mission is to teach the art and science of aerated composting, and to empower individuals and organizations of our world community to become advocates for sustainable agriculture and stewards of our land, air and water resources. We strive to change our society’s collective thinking from “Organic Waste Problem” to “Natural Resource Opportunity”, and to positively impact the world for generations to come.
