Blow molded containers of any size should not be included (e.g., 55-gal lon drums or 2 gl syrup containers). Product: Buckets, Pails, Oversized Rigid Plastics Source: Post-Consumer Material collected primarily from residential sources, may also include some material that has met its intended use from commercial establishments. Contamination: Total contamination should not exceed 5% by weight. ALLOWABLE CONTAMINANTS AT LOW LEVELS: These contaminants are tolerable at low levels. The following contaminants should not exceed 2% by weight of any of the following “individual” contaminants, unless noted otherwise. • Polypropylene rigid plastic (5% maximum) • Any other non-HDPE rigid plastic, including PET (#1), PVC (#3), LDPE (#4), PS (#6), Other (#7) and compostable plastic (e.g., PLA and PHA) (4% maximum of all combined) • Liquid or other residues • Loose paper or cardboard (OCC) • Aluminum cans CONTAMINANTS NOT ALLOWED: If present, these contaminants may result in rejection. • Any item with degradable additives • Containers which held hazardous materials, such as flammable, corrosive, or reactive products, pesticides, or herbicide • Any plastic bags or film • Any plastic foam • Other metal, wood, glass • Batteries • Electronics scrap, including items with circuit boards or battery packs • Bio-Medical waste/items (e.g., syringes, sharps, gloves, masks) • Rocks, stones, mud, oils, grease General: Refer to the General Information section for additional information.
