The SB 54 Advisory Board undertook an effort to identify key barriers and develop targeted recommendations to support the successful implementation of California's Plastic Pollution Prevention and Packaging Producer Responsibility Act, with a primary focus on advancing a circular economy for packaging and foodware. This report provides recommendations to transition from a linear system for managing packaging and foodware to one that prioritizes resource recovery, sustainable packaging, and waste prevention. The Advisory Board’s recommendations address critical challenges across five key areas: * Recyclability of Covered Materials * Compostability of Covered Materials * Reuse and Refill and other Source Reduction Systems * Cost Coverage for Local Jurisdictions * Plastic Leakage into the Environment
