About Us
Working together to grow healthy soils in California with compost.
The Association of Compost Producers (ACP) includes members who represent a wide range of compost stakeholders - from composters of all sizes, to equipment providers, municipalities, NGOs and more.
Our Story
ACP was founded in 1995 with the mission to foster collaborations in order to build healthy soil with compost in California. Over the last thirty years, ACP has worked to increase the value and volume of compost used in California through education, market development, and advocacy.
