To support the industry in addressing contamination at scale, the Consortium conducted an in-field study with 10 U.S. compost manufacturers to measure and characterize contamination across different points of the composters’ processes––and analyzed the financial cost to composters to handle contamination. The study examines five commonly held assumptions about contamination and compostable packaging, and breaks down in-field realities in a data-backed and easy-to-follow format.
