36 Guidelines for Plastic Scrap INSTITUTE OF SCRAP RECYCLING INDUSTRIES, INC. Copyright © 2022 Institute of Scrap Recycling Industries, Inc. Purge Plastic that has been melted and has hardened. This mate- rial has no set shape or form. Recovered Plastic Plastic materials which have been recovered or diverted from the solid waste stream. Does not include materials generated from and commonly reused within an original manufacturing process. Recycled Plastic Plastics composed of either post-consumer or recovered material or both. Regrind A generic term that refers to hard rigid plastic typically ground into a chip. Typically consists of material that is the same grade, color and type. It can be used in extrusion or molding processes. Rigid Plastic Container A package (formed or molded container) which maintains its shape when empty and unsupported. Shred Size reducedmaterial. The typical upper size can be between 3” to 12”, although in some cases the upper size can be as small as about 1”. Size range, characteristics should be agreed to between buyer and seller. Shredded Plastic Generic term. Material that contains a high plastic content. Typically contains 90% plastic content. Shredder Residue The remaining mixture after the majority of metals have been recovered from durable goods “shred.” The mixture can contain plastics, rubber, wood, glass, rocks, dirt, paper, film, textiles, wires and other metals missed during the metal recovery process. The predominant single material is often plastic, which can vary from about 15% to about 90% depending on the type of durable goods and the steps taken in the metal separation process. Size range, characteristics should be agreed to between buyer and seller. Uninstalled Can be found in multiple environments such as worksite, distribution centers or OEM facilities. The material has not been used due to a defect or other circumstance. It can be obsolete or surplus material. Material is that recovered from the distribution chain can also be categorized as “post-consumer.” Material recovered before the distribu- tion chain can be categorized as “pre-consumer.” Common issues for this category: The following list applies to all materials listed in this cat- egory. ■ Caps, enclosures, and labels are acceptable. ■ Product need not be washed, but preferred. PET Bottles (No PET Thermoforms) Description: Any whole Polyethylene Terephthalate (PET, #1) postconsumer bottle or jar with a screw-neck top that contains the ASTM D7611 “#1, PET or PETE” resin identification code and thatis clear, transparent green, or transparent light blue. All bott les should be free of content s or free flowing liquids . Closures (caps, lids, rings, and labels) may be left on bottles. Product: Polyethylene Terephthalate Bottles Source: Post-consumer material collected primarily from residential sources, may also include some material that has met its intended use from commercial establishments. “PET fraction” refers to the total weight of PET bottles in a PET bale, inclusive of caps and labels when still attached to PET containers, as a percentage of the total weight of that bale. There are 10 U.S. states with container deposit laws in place; all include a subset of PET containers. It is assumed that deposit bales will contain a high fraction of PET and that the grading scale above applies to all PET bales, including deposit. However, because the container mix, collection and aggregation process is defined through state statute, deposit bale specifications are not specifically addressed in this document. CHECK WITH YOUR BUYER(S) as to their allowances for:  Any other Color PET Containers (including fluorescents and opaques) Contamination: Total contaminants should not exceed the percentages, by weight, as defined by PET bale grade chart above. 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. • HDPE (#2), LDPE (#4), PP (#5) rigid packaging • Clear PET (#1) Thermoformed Plastic (e.g., clamshells, bakery trays, covers, deli containers, drink cups) • Aluminum cans • Loose paper or cardboard (OCC) • Liquid residues CONTAMINANTS NOT ALLOWED: If present, these contaminants may result in rejection. • PVC (#3) in any form • Chemically incompatible low temperature melting materials, including PS (#6), PETG, and PLA, as rigid or foam in any product. • Any #7 plastics, including polycarbonate bottles • Any non-packaging products • Any bulky rigid plastics PET Bale Grade Grade A Grade B Grade C Total PET bottle fraction by weight 94% or above 83 – 93% 73 – 82%
