The proposed bill establishes a comprehensive framework for mattress producer responsibility in Washington State, focusing on enhancing mattress recycling and reducing landfill waste. It requires mattress producers to join a producer responsibility organization (PRO) by January 1, 2027, and mandates that these organizations develop stewardship programs that include registration with the Department of Ecology, annual reporting, and compliance with approved plans. The bill introduces specific definitions related to mattress management and prohibits the sale of mattresses unless the producer, renovator, or retailer is registered with a PRO that has an approved plan. Retailers must also inform consumers about collection opportunities for discarded mattresses, promoting environmental sustainability and economic benefits through increased recycling jobs.

Additionally, the bill outlines the responsibilities of PROs, including the submission of detailed plans for mattress collection and recycling, public awareness initiatives, and funding mechanisms. It emphasizes public education and outreach, requiring organizations to provide accessible collection opportunities statewide and maintain financial reserves. The bill also establishes an advisory council for guidance on program implementation, grants immunity from antitrust laws for involved parties, and clarifies that it does not affect the authority of the Washington Utilities and Transportation Commission regarding solid waste collection. Furthermore, it introduces new sections to existing laws, including exemptions for PRO receipts and provisions for penalties related to environmental regulations, while ensuring that the remaining provisions of the act remain enforceable if any part is deemed invalid.
