Food waste scraps can be composted in a rich soil amendment

FacilityStarting in 2022, all jurisdictions will to need to provide organic waste collection services to all residents and businesses and divert these materials away from landfills and into recycling and recovery activities. 

Organic waste sent to the following facilities, operations, or activities is considered a reduction in landfill disposal, provided the organic waste is not subsequently disposed (see CCR Section 18983.1):

  • Recycling Centers
  • Compostable Material Handling Facilities
  • In-Vessel Digestion Facilities
  • Biomass Conversion Facilities
  • Soil amendment for erosion control, revegetation, slope stabilization, or landscaping at a landfill     
  • Land application
  • Animal feed

Starting January 1, 2022, CalRecycle will consider if additional technologies or processes not listed above count as a reduction in landfill disposal (see CCR Section 18983.2). 

For a technology or process to constitute a reduction in landfill disposal, the permanent lifecycle greenhouse gas emission reductions must be equal to or greater than the emission reductions from composting organic waste (0.30 MTCO2e/short ton organic waste).

Application Requirements

Submittal of an application is required for consideration of a new technology or process as a reduction in landfill disposal. Note that CalRecycle cannot make these determinations until after January 1, 2022, when the SB 1383 regulations go into effect. An application must contain the following information:

  1. Name and contact information of the person responsible for the information in the application.
  2. Explanation of the proposed technology or process.
  3. The quantity (i.e., short tons) and type (e.g., food, woody material, manure, paper products, sewage sludge, leaves and grass) of organic waste that will be processed annually.
  4. A description of each end use, including landfills, for any materials produced from the proposed technology or process. The description must include the quantity and characteristics of the material that will be sent to each end use.
  5. Each calculation, assumption, and emission factor used to determine the permanent greenhouse gas emission reductions of the technology or process.
  6. Documentation that each greenhouse gas emission factor has been peer reviewed or subjected to other scientifically rigorous review methods.
  7. An explanation of how the proposed technology or process will result in a permanent reduction in greenhouse gas emissions.
  8. A written statement that the information contained in the application is true, accurate, and complete.

Review Process

CalRecycle will notify the applicant, within 30 days of receiving the application, if additional information is required regarding the proposed technology or process.

  • Once all required information is received, CalRecycle, in consultation with the California Air Resources Board, will evaluate the application. CalRecycle will notify the applicant within 180 days as to whether the proposed technology or process is determined to result in a reduction in landfill disposal.
  • If CalRecycle determines that a proposed process or technology results in a reduction in landfill disposal, CalRecycle will post the results of the determination, including a description of the technology or process, on its website.
