California’s Senate Bill 54 requires all single-use packaging sold in the state to be recyclable or compostable by 2032, cuts single-use plastic waste by 65% and creates a $5 billion producer-financed fund for waste infrastructure. For anyone making California SB 54 compostable packaging, it is the largest single market opening in the sector.
How the law came about
California sets the regulatory pace for the rest of the US. SB 54 was signed in June 2022 as a compromise between environmentalists and the plastics industry, negotiated to head off a stricter ballot initiative. It works through an Extended Producer Responsibility framework, which moves waste management costs from municipalities onto producers.
Timelines and targets
Reduction targets phase in at 30% by 2028, 45% by 2030 and 65% by 2032, with all packaging recyclable or compostable at that point. The $5 billion fund pays for recycling and composting infrastructure, cleanup and R&D.
The qualifying rule has teeth: a material must hit a 40% recycling or composting rate in practice, not in principle. Compostable packaging needs certification to ASTM D6400 or equivalent standards.
Why it reaches beyond California
California’s economy exceeds $4 trillion, which is large enough that most brands will reformulate packaging for their whole US line rather than run California-specific SKUs. The $5 billion fund addresses the two bottlenecks at once: availability of bio-based polymers and capacity to process them. Brands are already signing with bioplastics suppliers.
What to watch
Oregon, Colorado and Maine have passed comparable EPR laws. Enforcement starts in 2027, with fines up to $50,000 a day. The binding constraint remains composting capacity willing to accept compostable packaging, which no legislation creates by itself. More in our Knowledge Zone.
