AB 876 (Organics Management Infrastructure Planning) Calculator


This calculator is provided to assist jurisdictions with compostable organics diversion planning. AB 876 (Chapter 727, Statutes of 2014) requires a county or regional agency to provide an estimate of organics generated and diversion capacity needed over a 15-year period. It is also intended to help in conjunction with meeting the requirements of AB 1826 (Mandatory Commercial Organics Recycling) which requires businesses that generate a specified amount of organic waste per week to arrange for recycling services for that waste, and for jurisdictions to implement a recycling program to divert organic waste from businesses subject to the law. Jurisdictions and counties will report to CalRecycle on their progress in implementing an organic waste recycling program, estimates of organic waste disposed, needed capacity to divert organics and planning to develop this infrastructure through the Electronic Annual Report (EAR) beginning with the 2016 report due in August 2017.


Keep an eye out for the annotations ( ) in various places throughout the calculator for definitions, user input instructions, and additional guidance on where predefined data originates from.

The first column on the left side shows default data as noted from the sources used.

The second column on the right side allows users to input their own data based on local knowledge of programs and demographics or to explore hypothetical outcomes based on potential changes in the future.

  • For the second column on the right, users must input all required empty data fields beginning with Step C.
  • Press the 'Use Default' button to carry over the default County data to all the user input fields which can then be edited as needed.
  • Fields in each step that require an entry to calculate data in further steps are noted with a red asterisk (*).

Note: None of the information in this calculator can be saved. If you'd like a record of your input please use the "Export to Excel" button located at the bottom of the calculator.

Note: Assembly Bill (AB) 1594 (Williams, Chapter 719, Statutes of 2014) mandates that as of January 1, 2020, the use of green material as alternative daily cover (ADC) will no longer constitute diversion through recycling and will instead be considered disposal. Learn more at FAQs About Green Material Used as Alternative Daily Cover (ADC). This material has not been included in waste characterization data and should be taken into account by counties when estimating needed organics diversion capacity. This additional tonnage should be included in Step E 'Additional Organics in 15 Years (TPY)' More information, including tonnage of green material used as ADC by individual jurisdictions, can be found on CalRecycle's Green Material Used as ADC page.
