California SB 54 and AB 793: the two laws rewiring PET demand

Two laws, one direction

California SB 54, the Plastic Pollution Prevention and Packaging Producer Responsibility Act, and AB 793, the state's minimum recycled-content law for beverage containers, attack the same problem from opposite ends. SB 54 restructures who pays for packaging waste. AB 793 dictates what the packaging must be made of. For anyone who produces, fills, or supplies plastic packaging sold into California, the combined effect is a schedule of hard obligations that runs from right now to 2032.

The reason this matters beyond California is scale and precedent. California is the largest packaging market in the United States, and both laws are templates: several states copied elements of AB 793 within two legislative sessions, and the SB 54 model of extended producer responsibility, EPR, is the blueprint that Colorado, Oregon, Maine, Minnesota, Washington and Maryland have followed with their own variations.

AB 793: the mandate that is already biting

AB 793 took effect in stages. Since 2022, plastic bottles covered by California's container redemption program must average at least 15% post-consumer recycled resin, PCR. On January 1, 2025 the requirement stepped up to 25%, and in 2030 it reaches 50%. This is not aspirational: beverage manufacturers that miss the average owe a penalty of 20 cents for every pound of post-consumer resin they fall short, assessed annually. Only the smallest players, those paying 15,000 dollars or less in annual processing fees in California, are exempt.

The design detail that industry planners underestimate is that the mandate is calculated as a fleet average across a manufacturer's covered bottles. That gives brands some flexibility in where they deploy recycled resin, but it also means procurement teams need a reliable, food-grade supply at portfolio scale, not just for a flagship SKU. A 25% average across every bottle sold in the largest US state is a very large, very inelastic demand block. At 50% in 2030, that block roughly doubles.

The law also gives CalRecycle authority, starting in 2025, to adjust the required percentage based on market conditions, recycling rates, and processing infrastructure capacity. That cuts both ways: it is a relief valve if supply genuinely cannot meet demand, and a ratchet if it can.

SB 54: the program that keeps slipping, and the deadlines that do not

SB 54's headline targets are set in statute for 2032: cut single-use plastic packaging and food service ware by 25%, achieve a 65% recycling rate for the covered material, and ensure 100% of it is recyclable or compostable. Producers fund the system through fees administered via a producer responsibility organization.

The rulemaking, however, has been a saga. Governor Newsom directed CalRecycle to redo its initial draft regulations in March 2025. CalRecycle then withdrew its proposed rules in January 2026 to revise them again, mainly around packaging for food and agricultural commodities, and ran an additional 15-day comment period from January 29 through February 13, 2026. Legislators have publicly pressed to delay fee assessment. Through all of it, the agency's position has been consistent on one point: the statutory deadlines are unchanged, and program implementation is expected in January 2027.

The practical read: the compliance machinery is late, the obligations are not. Companies that treat the regulatory turbulence as a reason to wait are compressing their own runway, because the 2032 targets and the 2027 program start bracket a fixed window in which packaging portfolios, supplier contracts, and data systems all have to change.

What the two laws do to the rPET market

Mandates change the character of demand. Voluntary brand commitments flex with the commodity cycle, and the industry watched exactly that happen when major brands trimmed their pledges, a shift we analyze in our review of the brand commitment reset. Legal mandates do not flex. A bottler selling into California in 2030 will need 50% PCR whether virgin resin is cheap that quarter or not.

• Demand becomes calendar-driven. The 2025 step-up already happened, 2027 brings the SB 54 program and its fees, and 2030 doubles the content requirement. Each date pulls forward procurement decisions.
• Food-grade supply is the choke point. Beverage bottles are food-contact packaging, so compliance material must carry food-contact clearance. That narrows the eligible supply to processes with FDA letters of no objection, a pathway we explain in our guide to the FDA LNO process.
• Eco-modulation will reward PET. SB 54 fees are expected to be modulated by recyclability, and PET bottles, with the strongest recycling stream of any plastic package, are positioned comparatively well. Formats that cannot demonstrate a recycling pathway will pay for it.
• Compliance is now a data problem too. Both laws run on reported, auditable numbers: pounds of PCR purchased, tonnage placed on market, verified content percentages. Suppliers that can document chain of custody stop being vendors and start being compliance infrastructure.

The national ripple

Washington, New Jersey, Connecticut and Maine have their own recycled-content requirements in various stages, and the EPR wave now covers a meaningful share of the US population. For a national brand, the operative question is no longer whether to run recycled content, but how to source enough certified, food-grade material to satisfy the strictest state it sells in, because packaging lines do not switch resin by destination. California's floor becomes the national specification by default. The same logic played out in the European Union, where union-wide targets locked the specification for every exporter, a dynamic we cover in our analysis of the EU recycled-content targets.

The compliance calendar, consolidated

Because the two laws interleave, the cleanest way to plan is a single California timeline. 2022: AB 793's 15% average took effect, the proving period most manufacturers cleared with room. January 2025: the average stepped to 25%, the first level that forces portfolio-wide procurement rather than flagship-SKU gestures. January 2027: SB 54's program is expected to go live, bringing producer registration, data reporting through the producer responsibility organization, and the first fee assessments. 2030: AB 793 reaches 50%, doubling the mandated volume in a single step. 2032: SB 54's statutory targets bite in full, the 25% source reduction, the 65% recycling rate for covered material, and the universal recyclability requirement.

Read as one schedule, the pattern is a staircase with no landings: from here to 2032 there is no year in which a covered producer's obligations do not either escalate or come under new measurement. The planning consequence is that packaging, procurement, and compliance functions can no longer work sequential handoffs. The 2030 content step, in particular, rewards companies that lock multi-year food-grade supply before the 2027 fee data makes every competitor's exposure visible to its board.

Note also the asymmetry in enforcement maturity. AB 793 already has a functioning penalty mechanism, assessed annually per pound of shortfall, while SB 54's fee architecture is still being finalized. Compliance risk through 2029 is therefore concentrated in the content mandate, which is exactly the obligation that depends on physical supply rather than paperwork.

What the fee fight is really about

The legislative pressure to delay SB 54 fees, and CalRecycle's repeated redrafting, are often reported as dysfunction. The more useful reading is that California is litigating, in public, the question every EPR system must answer: how much of the waste system's true cost lands on producers, and how finely the fees discriminate between packaging choices. Eco-modulation is where that discrimination happens. If fees are meaningfully lower for packaging with a proven recycling stream and verified recycled content, the fee schedule itself becomes a second recycled-content mandate, priced per unit rather than commanded per statute.

PET enters that contest with the strongest hand in plastics: an established collection system, national reclamation capacity, food-contact clearance pathways, and now a domestic-supply argument sharpened by tariffs. Producers who can document high recycled content in a demonstrably recyclable format should expect the fee mathematics to reward them, and the documentation habit, content certificates, chain of custody, supplier attestations, will convert directly into fee position. The companies treating 2026 as a documentation-building year are not being cautious. They are pre-negotiating their 2027 invoice.

What to watch next

Three markers will tell you how the next two years go. First, the final SB 54 regulations: their treatment of food-contact packaging and their fee schedule will set the real economics. Second, CalRecycle's use of its AB 793 adjustment authority: any move there signals how tight the agency believes food-grade supply actually is. Third, enforcement posture: the first published penalties under AB 793 will do more to move procurement behavior than any compliance webinar ever has.

The direction, though, is not in question. California has converted recycled PET from a sustainability story into a regulated input with a legal floor under its demand. Businesses that secure qualified supply early will treat these laws as a moat. The rest will treat them as a fine.
