    摘要： A novel composition for use in reducing and recovering metals, such as silver, and for use in stripping adhesive polymer layers from various polymer bases, such as polyester, and processes for using same are provided. The composition and variations thereof can be useful in separating an adhesive polymeric layer from the film for recovery of either. The composition comprises a reducing sugar/alkaline solution that is particularly useful for recovering silver from polyester photographic film where a silver halide light-sensitive emulsion layer is adhered to the polyester film by a polymeric adhesive resin, such as resins containing copolymers of polyvinylidene chloride and polyvinyl chloride. Processes for separation and recovery are also disclosed and claimed.

    摘要： The method comprising; shredding the photographic film into a plurality of fragments to be processed; swelling the fragments to be processed formed in the shredding step by dipping each of these fragments to be processed into hot water; and drying the fragments to be processed swollen in the swelling step by applying an impact frictional striking force to each of these fragments to be processed, peeling layers other than a resin material base of the photographic film, i.e., a protective coat, an emulsion layer, a base coat layer, from each fragment to be processed and classifying these layers, and grading the resin material base so as to be resin material to be recovered.

    摘要： Procédé en une étape servant à produire des diacétates de cellulose à partir de pellicules développées contenant du triacétate de cellulose comme leur base. Le procédé consiste à utiliser un acide organique tel que l'acide acétique et un agent de solvolyse tel que l'alcanol ou l'eau. L'hydrogène et un catalyseur d'hydrogénation peuvent éventuellement être utilisés. Le procédé permet de recycler de manière simple un matériau qui n'est actuellement pas recyclé en quantités appréciables.
