IN Brief:
- The US Plastics Pact has released a report on composting infrastructure and compostable packaging acceptance.
- The report calls for harmonised policy, labelling standards, recognised certification, and collection infrastructure.
- Food-contaminated packaging remains a key use case where compostables could complement recycling and reuse systems.
The US Plastics Pact has called for stronger policy alignment, investment, and labelling standards to scale compostable packaging in the United States.
Its report, Enabling Composting at Scale, sets out policy frameworks and investment routes intended to improve composting infrastructure and compostable packaging acceptance. The central argument is that compostable packaging can help capture heavily food-contaminated materials that are poorly suited to conventional recycling, but only where collection systems, certification, labels, and end-market acceptance are aligned.
Foodservice, takeaway, events, and on-the-go consumption are important use cases because food waste and packaging are often generated together. Where separation is difficult, compostable packaging can allow food and packaging to be collected in one stream, reducing contamination in recycling streams and supporting organics recovery.
The US compostables landscape remains uneven. Policies differ by state and locality, composting infrastructure is inconsistent, and acceptance criteria vary between facilities. Some systems accept certified compostable packaging, while others reject it because of contamination concerns, processing limitations, PFAS questions, consumer confusion, or uncertainty over degradation performance.
The US Plastics Pact is calling for compostables to be recognised alongside recyclable and reusable options, with national labelling standards, third-party certification logos, standardised terminology, and penalties for misleading claims. The report also links adoption to food waste diversion mandates, landfill restrictions, funding mechanisms, procurement standards, and clear acceptance criteria.
For food and beverage companies, compostable packaging is often discussed as a material substitution, but it functions as an infrastructure dependency. A compostable cup, tray, wrap, or film achieves little if it enters landfill, contaminates recycling, or is rejected by the composter. The pack has to be designed for the system that will actually handle it after use.
The US debate sits alongside tightening packaging rules in other markets. India’s 40% recycled PET mandate for food packaging shows how recycled content rules are becoming more direct, while Lecta’s shift to no-PFAS-added food packaging grades reflects growing scrutiny of chemical safety in food-contact materials.
Compostables add a different kind of complexity. They need food-contact compliance, conversion performance, sealing or barrier function, storage stability, shelf-life protection, and line compatibility. They also need disposal instructions that consumers and foodservice operators can understand quickly. If those elements are not aligned, the environmental benefit becomes difficult to defend.
There is also a continuing debate over which applications are suitable. The strongest cases tend to be where food contamination is unavoidable and recycling performance is already weak. Heavily contaminated foodservice items, closed-loop event formats, and organics-collection settings may provide clearer value than switching recyclable rigid packs into compostable alternatives without matching infrastructure.
The report pushes the discussion towards system design rather than simple material claims. Compostable packaging will scale responsibly only where procurement, packaging development, waste operators, policymakers, certifiers, composters, and customers work to the same acceptance rules.
Until then, compostability remains conditional. A pack may be technically capable of composting, but the market still has to collect, sort, process, and explain it at scale.
