CA AB891

Requires beverage manufacturers to receive a 10% processing fee reduction starting January 1, 2025, for beverage containers made with nonpetroleum biomaterials (limited to 50% of total container weight), contingent on third-party certification of the material percentage and recyclability.

Defines nonpetroleum biomaterials as materials from non-food feedstocks including agricultural residues, wood waste, yard clippings, and nonrecyclable paper, but excludes crops grown specifically for plastic production and materials that compromise recyclability.

Requires independent third-party certification entities (accredited under ISO/IEC 17025 or ISO/IEC 17065) to certify the percentage of nonpetroleum biomaterials and confirm that their use does not reduce container recyclability.

Authorizes the Department of Resource Recovery and Recycling to charge manufacturers a fee covering reasonable implementation costs and establishes a legislative goal of 15% or more nonpetroleum biomaterials in virgin plastic by January 1, 2030.

Allows beverage manufacturers to voluntarily report the amount of virgin plastic derived from nonpetroleum biomaterials used in containers subject to the California Redemption Value, with information posted on the department's website.
