LEGISLATIVE COUNSEL’S DIGEST
Existing law prohibits a person from selling or offering for sale a product, as defined, that is labeled with the term “compostable” or “home compostable” unless, among others, the product meets a specified ASTM standard specification, has OK compost HOME certification, and meets a standard adopted by the Department of Resources Recycling and Recovery. Existing law requires the department to review revisions to the ASTM standard specification, as provided. Existing law authorizes the department to adopt a standard different from an ASTM standard if adopted or developed by a standard-setting organization recognized by the department, the standard adds qualifications to an ASTM standard specification, and the standard is more stringent than an ASTM standard specification, as provided. Existing law exempts a fiber product that is demonstrated to not incorporate any plastics or polymers from complying with any of these ASTM standards.
This bill would instead prohibit a person from selling or offering for sale a product that is labeled with the term “compostable” or “home compostable” unless the product has OK compost HOME certification or meets a standard adopted by the department. The bill would repeal the requirement for the department to review revisions to the ASTM standard specification. The bill would instead authorize the department to adopt an existing standard different from an ASTM standard specification if the standard is adopted or developed by a standard-setting organization recognized by the department. This bill would exempt a fiber product that is demonstrated to not incorporate any plastics or polymers from requirements for labeling compostable products, as specified, unless the department adopts a standard for compostable fiber products.
This bill, on and after January 1,
June 30, 2027, would prohibit a person from selling or offering for sale a product in this state that is labeled with the term “compostable” or “home compostable” that is made wholly or partially of plastic, as defined.
This bill would exempt from prohibition a food service establishment’s use of plastic single-use food service ware that is accepted by a recycling collector that services the jurisdiction in which the food service establishment operates, as specified. The bill would provide that this exemption does not preempt a local requirement for food service establishments to use compostable or reusable service ware or otherwise limit the authority of a local government to regulate service ware outside of the exemption, as specified.
Existing law requires a compostable bag that meets an ASTM standard specification described above to comply with certain labeling requirements.
This bill would repeal those labeling requirements.
The people of the State of California do enact as follows:
SECTION 1.
Section 42281.2 of the Public Resources Code is amended to read:
42281.2.
(a) On and after January 1, 2025, a store, as defined in Section 42280, shall not provide a precheckout bag to a customer if the bag is not one of the following:

(A) Is eligible to be labeled with the terms “compostable” or “home compostable” pursuant to Section 42357.
(B) Has a minimum 15-inch mouth width.
(2) A recycled paper bag.
(b) For purposes of this section, a “precheckout bag” means a bag provided to a customer before the customer reaches the point of sale, that is designed to protect a purchased item from damaging or contaminating other purchased items in a checkout bag, or to contain an unwrapped food item, such as, but not limited to, loose produce, meat or fish, nuts, grains, candy, and bakery goods. “Precheckout bag” does not include a bag used to prepackage items prior to their arrival in a store.

(a) California is a leader in composting policy and infrastructure.
(b) California has the largest composting program in the country.
(c) California hosts a large share of the country’s full-scale composting and organics recycling facilities.
(d) California’s organic recyclers and compost operators have created a sustainable, scalable industry model for the state, the nation, and the world that demonstrates that putting clean, recycled, composted organic materials back into the ground is among the most predictable, cost-efficient, productive, and eco-friendly uses of organic waste.
(e) As leaders, California’s organic recyclers and compost operators strive to develop markets to increase sales of clean compost, mulch, and wood products.
