various hercules brand coagulants is added to coagulate the silver at ambient temperature metallic silver settles out and the organic impurities may be burned therefrom to obtain a highly purified form of metallic silver the polyester chips are dried to provide recyclable polymer base that is essentially free from pvdc based resin the present composition may also be utilized to recover reusable and recyclable polyester from waste polyester having only a polymeric adhesive layer adhered thereto in the manufacture of photographic film some film is scrapped prior to attachment of the silver halide light sensitive layer much of this waste film has already been coated with the pvdc based resin the present composition may be employed for removing the pvdc based resin layer and obtaining usable polyester even when a metal is not present in such a case a reducing sugar is not necessary the same steps described above are utilized wherein the ph of the slurry is initially maintained above about 11 while heating in the presence of the inventive composition and is then lowered to about 8 5 to precipitate the pvdc based resin the pvdc based resin is then separated from the polyester and a clean recyclable polymer is obtained although crystalline fructose is used in the examples herein as the reducing agent any equivalent reducing sugar such as fructose sucrose and other reducing polyhydroxy aldehydes and ketones could be employed sugars or sacharrides are generally classified as polyhydroxy aldehydes and ketones or as substances that hydrolyze to yield polyhydroxy.
