Organic Materials Management

Locating Compost and Mulch Facilities

Are you looking to either purchase compost/mulch or dispose of organic materials? This search page will locate compost and/or mulch facilities by county. The data is continuously updated.

Producers/Suppliers

To be included on the list, producers must meet the following criteria: (1) Products must be available in bulk and will be listed only in counties where materials are produced or stored, (2) All products produced must comply with the CIWMB composting facility regulations, PRC Title 14: Chapter 3.1.

Every composting facility or operation in compliance with these regulations is listed. Mulching and vermicomposting, which are considered "excluded activities" in the composting facility regulations, are also be listed if they are in compliance with applicable State Minimum Standards.  In addition, composting businesses are listed with "permit pending" status if appropriate permitting paperwork has been submitted to local agencies and verified with the local enforcement agency (LEA) by Board staff.  If the LEA allows a compost facility to operate and make product, and the operation is in compliance with State minimum standards, a "permit pending" status will be designated and reviewed annually. See our list of LEAs to find contact information for your area.

Note: Identification of individuals, companies, and products on this list does not constitute endorsement by the California Integrated Waste Management Board. The Board distributes/publishes this information to increase public awareness and to build markets for recycled products made from organic materials collected in California jurisdictions. This list should not be considered comprehensive.

Nationwide Facilities Database

BioCycle has launched www.findacomposter.com, a searchable database of composting facilities in North America. It includes all regulatory-compliant composting operations to aid generators of compostable feedstocks and other interested parties in locating facilities that are permitted to receive those feedstocks.
