In early 2025, Cascadia conducted a disposal facility-based material characterization study on behalf of CalRecycle—a crucial first step in implementing the California Plastic Pollution Prevention and Packaging Producer Responsibility Act (SB 54). This act establishes extended producer responsibility (EPR) for single-use packaging and food service ware, aiming to manage these items across all sectors of the economy. By 2032, California’s goal is to reduce single-use plastic in these products by 25%, recycle 65% of single-use plastic packaging and food service ware, and ensure that 100% of these items are recyclable or compostable. Cascadia, together with our partners at ReCreate Collaborative, MSW Consultants, and Stina Inc., led this study to gather foundational data that will help California achieve these ambitious goals.

This waste characterization study addresses a large, unique, and complex list of materials that must be managed by the EPR system. It provides critical baseline data on the extent to which these materials are currently ending up in landfills. This waste characterization process has also helped CalRecycle to clarify and refine its understanding of the materials covered by SB 54. This data, provided by Cascadia, will be analyzed by CalRecycle, which is expected to release its report soon. This study is a significant step towards better managing plastic waste and achieving the sustainability targets set by SB 54.

Cascadia, on behalf of CalRecycle, worked with partners at ReCreate Collaborative, MSW Consultants, and Stina Inc. to develop this foundational study.
