Appeal No. 1997-1869
Application 08/215,462
11. A process for reclaiming and preparing plastic containers for recycling
said plastic which plastic containers have residual material such as an organic
liquid phase and a solid waste associated therewith comprising the steps of:
a) cutting said containers into relatively large plastic pieces that are
small enough to allow aqueous solvent to reach each area of
said pieces,
b) placing said cut plastic pieces into a washer with an aqueous
based solvent adapted to loosen and suspend said residual
materials,
c) agitating said aqueous solvent by rotating or reciprocating said
washer or a part thereof to loosen, suspend and remove said
residual material,
d) separating said aqueous solvent containing suspended residual
material from said plastic pieces by simply draining said
aqueous solvent from said plastic pieces,
e) separating said aqueous solvent from an organic liquid residual
material and from a solid waste residual material,
f) regenerating said aqueous solvent and recycling said aqueous
solvent in the process,
g) recovering a useable organic liquid residual material free of
solid waste residual material and free of aqueous solvent,
h) recovering a solid waste residual material free of organic liquid
residual material and free of aqueous solvent, and
i) passing cleaned plastic pieces to a plastic recycle process free
of organic liquid residual material, solid waste residual material
and aqueous solvent.
