Public Resources Code (PRC) Section 42355.51(d)(1)(B)(i) directed the Department of Resources Recycling and Recovery (CalRecycle) to conduct and publish a characterization study of material types and forms that are collected, sorted, sold, or transferred by solid waste facilities. The findings of this study are detailed in the SB 343 Final Findings Report – 2023/2024 (DRRR-2025-1750) published on April 4, 2025. 

CalRecycle has since evaluated new information submitted to the department relating to the collection and sortation of Gable-Top Cartons – Non-CRV and Aseptic Containers – Non-CRV, identified by material type and form (MT&F) codes X02 and X03 (collectively referred to as “cartons”). Under PRC section 42355.51(d)(1)(B)(iii), CalRecycle may publish additional information that was not available during the most recent periodic characterization study conducted under PRC section 42355.51(d)(1)(B)(ii).
