Reclaimer:
An organization that further processes recyclable materials.
When the reclaimer finishes processing, the material
is ready to be remanufactured into a new product. Reclaimers
sell post-consumer plastic pellets or flake to product
manufacturers. Some reclaimers also manufacture end
products. (Waste Reduction Strategies for Rural Communities,
prepared by the MaCC Group, with support from Tennessee
Valley Authority, March 1994).
Recovered Material:
Materials and by-products that have been recovered (or
diverted) from solid waste. It does not include those
materials and by-products generated from and commonly
reused within an original manufacturing process (industrial
scrap). (Standard Classification for Recycled post-consumer
plastic Polyethylene Film Sources for Molding and Extrusion
Materials, American Society for Testing and Materials
(ASTM), April 1994).
Recovery:
The process of obtaining materials or energy resources
from solid waste. (Code of Federal Regulations, Title
40, 245.101).
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:
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: See Handlers and Reclaimers.
(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:
Any of a class of solid or semi-solid organic products
of natural or synthetic origin, generally of high molecular
weight with no definite melting point. Most resins are
polymers. (Plastics Engineering Handbook of The Society
of the Plastics Industry, Inc., edited by Michael L.
Berins, 1991).
Resource Conservation:
A wide array of activities that include reducing the
energy consumed and pollution generated during manufacture
and over the useful life of a product; extending the
life of material used to make a product through reuse
and recycling; reducing the amount of material needed
to make a product initially; utilizing options available
for recovering value from materials when they are ultimately
discarded, such as energy recovery and fuel pellets.
(American Plastics Council, Washington, DC, 1996).
Responsible Care:
The chemical industry's health, safety and environmental
performance improvement initiative launched in 1988
by the Chemical Manufacturers Association (CMA). Developed
to respond to public concerns about the manufacture
and use of chemicals, CMA members commit to support
a continuing effort to improve the industry's responsible
management of chemicals. (1994-95 Responsible Care Progress
Report, Chemical Manufacturers Association).
Rigid Plastic
Container:
A formed or molded plastic container that serves as
a package, and maintains its shape when empty and unsupported.
(How To Develop a Viable post-consumer plastic Handling
Business, APC, 1993).
Random
Copolymers
Random copolymers are produced by statistical insertion
of units of ethylene or higher a-olefins (mostly butene,
also in combination with ethyle to give terpolymers).
Through this, the glass transition temperature and melting
point are lower than in homopolymers, allowing better
sealability and application at temperatures below zero
degree.
Reclaimed Rubber
The product resulting from the treatment of vulcanized
scrap rubber in various operations, such as grinding,
defibering and devulcanizing by heating with aqueous
alkali or with a metallic chloride solution and reclaiming
agents, and refining, whereby the fabric is destroyed
and the rubber compound is recovered and made suitable
for use in the manufacture of rubber goods; the fiber
may also be removed mechanically, followed by devulcanization
of the rubber.
Ring-opening polymerization
A polymerization in which a cyclic monomer yields a
monomeric unit which is acyclic or contains fewer cycles
than the monomer. If the monomer is polycyclic, opening
of one ring is sufficient to classify the reaction as
ring-opening polymerization
