What is meant by subscribing to a service that includes mixed waste processing that diverts recyclable materials from disposal and that yields diversion results comparable to source separation?

Subsection 18837(a)(2) Specification

Subsection 18837(a)(2) specifies a method that a business may take to meet the requirement to recycle the business’s commercial solid waste:

by subscribing to a recycling service that may include mixed waste processing that diverts recyclable and/or compostable materials from disposal, yielding diversion results comparable to source separation.


In reality, however, there is not sufficient data or standards available to make a comparison to source separation, and therefore CalRecycle is not establishing such a threshold at this time. The language in the existing statute has been interpreted differently by various stakeholders regarding whether or not it establishes a particular threshold for mixed waste processing. On its face, the statute clearly does not do so. Instead, statute has provided a subjective standard to be evaluated on a case-by-case basis that allows flexibility for compliance. While Subsection 42649.2(b)(2) allows for a recycling service that may include mixed waste processing comparable to source separation as part of that recycling service, by using the term “may” instead of “shall” in this section, it does not require it.

That is, mixed waste processing is not necessarily required and therefore a recycling service can include other programmatic aspects. Thus, the recycling service may include more than just mixed waste recycling (consistent with the “may” in statute), but also emphasizes the need for the overall recycling service to yield comparable results to the other compliance alternative in (b)(1) (source separation). Mixed waste processing is intended here to include a myriad of processes to recover recyclable and/or compostable materials from solid waste. This Subsection is not intended to change marketplace dynamics or express a preference for any particular diversion activity, program or process over another. It is intended to provide local governments with flexibility in designing programs specific to their community.

Good Faith Effort

While no single quantitative recovery rate standard exists, the section does establish an expectation that overall diversion results from a recycling service that includes mixed waste processing, and that may include other programs and activities, will be comparable to the overall diversion results of recycling services that rely on source-separated processing of recyclables, and that may also include other programs and activities. In lieu of a quantitative standard, CalRecycle will review jurisdiction compliance on a case-by-case basis using the “good faith effort” standard as already provided in statute (See PRC 41825(e)).

As part of its evaluation of local jurisdiction program implementation, the diversion performance of a particular facility may be considered by CalRecycle to see if the facility’s recovery appears to be significantly low. In this case CalRecycle would take into account relevant factors such as, but not limited to, the character and composition of the solid waste stream generated in the jurisdiction, the nature of collection systems in the jurisdiction, and the nature and amount of feedstock processed at facilities used for solid waste generated in the jurisdiction. That is, CalRecycle would conduct a case-by-case qualitative evaluation in the context of the entire set of programs in a jurisdiction, whether the facilities involved are mixed waste processing or single-stream material recovery facilities.

Additionally, businesses that choose to subscribe to a recycling service are not required by statute to determine if a mixed waste processing facility that is part of that service is yielding comparable results (e.g., they do not have to survey facilities and ask for recovery data).

Future Developments

As for whether or not CalRecycle should develop a quantitative standard of what constitutes “comparable to source separation” for mixed waste processing, CalRecycle has committed to working on this issue in the future. Prior to the formal rulemaking, this was the subject of considerable discussion and controversy. A working group convened by CalRecycle determined that there is not sufficient information at this time to promulgate such a standard. This is due in part because of variations in feedstock, processing technologies, residuals composition, lack of reporting, etc. However, CalRecycle recognizes that future work is needed on this issue as part of its other work on AB 341 (report on how to meet 75% diversion) and that this may lead to future rulemakings that establish performance requirements for mixed waste processing facilities.
