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, 2026, and mandates registration with the Department of Ecology by July 1, 2026. The PRO is tasked with developing and implementing a recycling plan, ensuring compliance, maintaining financial accountability, and providing education to retailers and consumers. Starting July 1, 2029, retailers will only be allowed to sell mattresses from producers who are members of an approved PRO. The bill emphasizes environmentally sound management practices and includes provisions for penalties for non-compliance, as well as annual reporting requirements from the PRO. Additionally, the bill introduces new legal provisions, including section 13 of this act and chapter 70A.--- RCW (the new chapter created in section 19 of this act), which establish guidelines for permit management and create a responsible mattress management account to receive penalties. It outlines the responsibilities of PROs, including the submission of contingency plans, performance goals for collection and recycling, and the requirement to provide accessible collection sites. The legislation also creates an advisory council to guide the program and clarifies that local governments retain authority over solid waste management. Overall, the bill aims to promote environmental sustainability, enhance recycling efforts, and ensure compliance with established standards.
