Study finds compostable produce stickers can reduce plastic contamination in compost, support food safety, and align Washington with global standards
Plastic produce stickers are a persistent contaminant in Washington’s compost management systems. They decrease the value of compost and add plastic to soil. Compost facilities already spend about 21% of operating costs managing contamination, yet no system can remove stickers effectively.
As Washington expands food waste collection under its Organic Management Laws (HB 1799 and HB 2301), the problem is expected to grow. In 2024, the Washington State Legislature considered a ban on plastic produce stickers and directed the Department of Ecology, in consultation with the Washington State Department of Agriculture (WSDA), to study produce sticker technologies and recommend next steps.
Ecology retained Greene Economics to evaluate produce labeling options—like compostable stickers, laser etching, and ink-based printing—and their impact on compost and recycling facilities. Our team worked closely with Ecology and WSDA to review legislative requirements, prior studies, and research from other states and countries. We interviewed fruit growers and packers, distributors, sticker and adhesive manufacturers, the International Compost Alliance, and other experts. Each technology was assessed for compostability, toxicity, cost, printability, product performance, legal barriers, and more. We also evaluated how emerging international standards could shape Washington growers’ labeling and export decisions.
Compostable stickers emerged as the most viable alternative, compatible with existing packing equipment but limited by higher costs and adhesive stock availability.
Our study informed Ecology’s recommendation to delay banning plastic produce stickers and allow time for global compostable sticker standards to develop. By staying involved in the global conversation, Washington can help shape solutions that support growers, composters, and the environment.
