• Update to Covered Material Categories: This document provides an update of CMCs relative to the December 31, 2024, version, and does not include an update to determinations of recyclability or compostability. CalRecycle will update the recyclability and compostability determinations by January 1, 2026 to meet requirements of Public Resources Code (PRC) section 42061(e). Only one change was made, which is the addition of one new CMC.
