Compostable Materials

Compostable materials make up well over one-third of most jurisdictions' waste streams. State mandated diversion requirements have resulted in an increasing number of compostable material processing operations. An increased reliance on composting, chipping and grinding, and other compostable material processing operations is expected in order to meet State-mandated diversion goals.

To assist local enforcement agencies and facility operators with compostable materials management issues, the California Department of Resources Recycling and Recovery (CalRecycle) has developed resources for local enforcement agencies (LEA) and facility operators on compostable materials management. These include:

Current Initiatives

The current regulatory review as part of Strategic Directive 8.3, includes an in depth look at appropriate contamination levels in green material, food waste permits, agricultural composting, odors and other concerns at compostable materials processing operations. CalRecycle staff continues to work on the following areas: 

Additional Guidance

CalRecycle staff has also developed an Organic Materials Management Web site where you'll find the Organics Toolbox for jurisdiction's diversion and information on compost, mulch, grasscycling, and other topics related to the management and use of organic resources.
