Transfer and processing facility employees sort material on conveyer belts.

SB 1383 requires California to implement statewide organic waste collection to divert as much organic waste—including yard and food waste, paper, and cardboard—from landfills as possible. 

Haulers collect material through curbside collection programs, then deliver it to transfer/ processing facilities and operations, which sort it into clean streams of organic materials, recyclables for further processing, and items for disposal at landfills

Transfer/Processing Facility and Operation Requirements

Transfer and processing facility employee oversees material sorting.


The passage of SB 1383 resulted in changes to Title 14 CCR, Chapter 3, Article 6. The following is a brief summary of these changes.

Depending on the type of collection service, haulers may deliver mixed organics (MO) or source-separated organics (SSO) to transfer/processing facilities or operations. At the facility, these two streams of material must be processed separately, as they each have different handling requirements.

The operator must conduct sampling of the waste streams to determine how much organic material is recovered and how much is disposed to calculate the recovery percentage.

The quality of the final recovered organics depend upon the quality of the feedstock material:

  • All material that a transfer/processing facility or operation sends to a recovery activity (like composting or anaerobic digestion) should be 80 percent “clean” or less than 20 percent of incompatible material by 2022 and 90 percent clean or less 10 percent of incompatible material by 2024.
  • A transfer/processing facility or operation that does not meet the cleanliness standard can only send organics to a facility or operation that can meet the cleanliness standard or the acceptable levels of organic waste sent to disposal.

Incompatible Material Limits

Processing facilities that can remove 90% of the contamination within processed organic materials can send the material to any type of recovery activity. Facilities that cannot remove at least 80% of incompatible material by 2020 and 90% of incompatible material by 2024 must send organic material to a facility that can meet the cleanliness standard or the acceptable levels of organic waste sent to disposal. These cleanliness standards ensure that organics recovery and recycling facilities have clean streams of feedstock to produce high-quality products.

Transfer/processing operators are required to perform quarterly evaluations of gray container collection stream to determine the amount of organics collected in that waste stream.

Transfer/processing operators are also required to maintain records and report to CalRecycle sampling results and daily outgoing weights of organic material sent for recovery and disposal.

Overview of the changes to Title 27 CCR, Division 2, Chapter 3, Landfill Requirements

The passage of SB 1383 resulted in changes to Title 27 CCR, Division 2, Chapter 3. A summary of changes to the landfill requirements include:

  • New or expanding landfills must implement organic waste recovery activities.
  • No later than January 1, 2023, the operator must submit to CalRecycle an Organic Disposal Reduction Status Impact Report that analyzes the potential impacts to the landfill’s design and operation that may result from a reduction in the amount of organic waste disposed at the landfill.

Changes to Solid Waste Facility Permit Requirements

The passage of SB 1383 resulted in changes to Title 27 CCR, Division 2, Chapter 4, including changes to the filing and processing requirements for a solid waste facilities permit (SWFP) application:

  • For new and expanded solid waste facilities, the solid waste facilities permit applicant shall hold a public meeting with any affected disadvantage communities within 180 days of submittal of the permit application package.
  • For new and revised SWFP applications, the enforcement agency (EA) shall conduct an informational meeting that is located as close to the facility and affected disadvantage communities as reasonably practical, if no suitable location exists within one mile of the facility.  Informational meetings should be held on a day and time that the EA determines will enable attendance by residents, especially those of affected disadvantage communities, living in the vicinity of the subject facility.
