Recycling
The series of activities by which discarded materials are collected, sorted, processed and converted into raw materials and used in the production of new products.

Recycling Markets
These markets are made up of individuals or businesses that purchase post-consumer plastic and/or post-industrial recyclable materials. Markets specify what kind of recyclables they purchase, what price the material is worth and in what form the material is needed. Recycling markets for plastics fall into two broad categories: (Waste Reduction Strategies for Rural Communities, prepared by the MaCC Group, with support from Tennessee Valley Authority, March 1994).

Redemption Center
A centrally located depot to which consumers bring recyclables that provides payment for delivered materials. (The Blueprint for Plastics Recycling, The Council for Solid Waste Solutions, 1991).

Resin
This is a short term for Polyethylene (PE) resin. The three types of PE resins are LDPE, LLDPE and HMW-HDPE (see below). Other plastic resins include vinyl, polypropylene, styrene and nylon.

  • LDPE (Low Density Polyethylene) - This resin was used with older can liner technology. Resin has good clarity but weak film strength. Today it is used primarily for Food and Utility bags.
  • LLDPE (Linear Low Density Polyethylene) - This is the primary type of resin used in modern can liner manufacturing technology. Bags made from LLDPE film provide excellent combination of film strength, puncture resistance and tear resistance.
  • HMW-HDPE (High Molecular Weight - High Density Polyethylene) Bags made from HMW-HDPE resin provide excellent film strength and puncture resistance, but less tear resistance than LLDPE.
  • Butene - One of three types of LLDPE resin. Butene has weaker film-strength properties than Hexene or Octene.
  • Hexene - One of three types of LLDPE resin. Some manufacturers use a Higher Alpha Olefin (High Grade Hexene) in the manufacturing of can liners. Properties include high film strength and increased tear resistance.
  • Octene - One of three types of LLDPE resin. Used in other applications because of its excellent physical properties.
  • Prime Resin - Refers to the usage of high-quality, "fresh from the reactor", resin.
  • Blended Resin - Refers to the combination of two or more types of resin.
  • Reprocessed Resin - Refers to resin that has been used at least once before. Can be post-industrial (scrap) or post-consumer (recycling). Property of resin is decreased each time it is reused
