PAPER RECYCLING TERMS

BEATER-DYED: Paper dyed or colored during the paper manufacturing process.

BEATER-DYED: Paper dyed or colored during the paper manufacturing process.

BOXBOARD: Paperboard made from mixed papers having folding properties and thickness used to manufacture folding or set-up boxes.

CHIPBOARD: Low density paperboard with 0.006 thickness or heavier.

COATINGS: A layer of adhesives, clays, varnish or any barrier applied to paper.

CORES: Paper tubes on which rolls of paper may be wound for shipment.

CORRUGATED CONTAINERS: Shipping containers made with kraft paper linerboard and corrugated medium.

FLYLEAF/SHAVINGS: Trim scrap from printing operations.

GROUNDWOOD: Paper made with fibers produced without chemical pulping.

JUTE: Strong, long-fibered pulp made from hemp.

KRAFT: Paper made from sulfate pulp (synonyms: brown and strong).

LINERBOARD: Outside layers of a combination board used to manufacture corrugated shipping containers.

MEDIUM: The inner corrugated fluted material used to manufacture corrugated shipping containers.

OFF-SHORE/ASIAN: Denotes corrugated shipping containers manufactured overseas and containing bogus liners or medium. (Color is somewhat lighter/more yellow than North American produced materials).

TEST LINER: Liners, which are the outer ply of any kind of paperboard, containing 100% recycled material.

WET STRENGTH: Paper Papers that have been treated with a moisture-resistant chemical that inhibits pulping.

FREESHEET: "woodfree" papers are made with a chemical pulp (or kraft) process that removes lignin and other components of wood from the cellulose fiber.

GROUNDWOOD: In contrast to freesheet, groundwood papers are originally made with mechanically ground pulp, which retains the lignin which makes paper turn yellow and brittle. Groundwood now includes pulp from hybrid systems, such as semi-mechanical, thermo-mechanical and chemi-thermomechanical, that remove some but not all of the lignin. Freesheet papers may contain up to 10% groundwood pulp and still meet specifications. Groundwood is a contaminant in recycling systems for freesheet papers because it has shorter fibers and introduces lignin. Generally, recovered paper with groundwood is downgraded for lower end-use products like corrugating medium and tissue.

PLASTIC RECYCLING TERMS

RIGID PLASTIC CONTAINER: A package (formed or molded container) which maintains its shape when empty and unsupported.

PLASTIC BOTTLE: A rigid container which is designed with a neck that is smaller than the body. Normally used to hold liquids and emptied by pouring.

PLASTIC FILM: A thin flexible sheet which does not hold a particular shape when unsupported.

RECYCLED PLASTIC: Plastics composed of either post-consumer or recovered material or both.

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.

POST-CONSUMER: Products generated by a business or consumer that have served their intended end use and have been separated or diverted from the solid waste stream for the purpose of recycling.

NATURAL: Plastics that have no color and are clear or slightly opaque such as milk jugs, and the typical clear uncolored water bottles. Natural is different from White.

PIGMENTED/DYED: Plastics that may be clear or opaque and are colored white, black or any other color. A clear water bottle that is green is considered pigmented. Additionally, white plastics are considered pigmented.
