What is Recycling Contamination?

Recycling contamination occurs when non-recyclable items or improperly cleaned materials enter recycling streams, reducing efficiency and material quality. Contaminated loads can slow down processing, increase operational costs, and sometimes result in entire batches being rejected. Common contaminants include food waste, plastics not accepted by local programs, and hazardous materials. High contamination rates also pose safety risks for workers at material recovery facilities (MRFs). Proper sorting, rinsing, and following local recycling guidelines are critical for maintaining the integrity of recovered materials and supporting sustainable waste management practices.
