    Student thesis: Master's Thesis


    The thesis describes experimental work to remove primary contaminants viz silver and poly (vinylidene)chloride (PVDC) coating, from X-ray film and subsequent recovery of poly (ethylene) terephthalate (PET) economically.

    The thesis commences with a review of the literature, concerning the recycling and recovery of (PET), from X-ray films and related materials.

    Following a discussion of the properties of (PVDC) and PET, a programme of experimental work is outlined, for de-silvering the X-ray film, removal of PVDC and recovery of PET.

    From a consideration of the preferred experimental procedure, an estimated materials and process costing is outlined, for a proposed PET recycling plant.

    Management and recycling, within the EC, specifically in relation to the recovery of PET, is discussed, particularly in relation to the legal restraints on the disposal of plastics to land-fill sites.

    A flow-sheet and description of the proposed recycling plant, including control equipment and outline mass and energy balances, concludes the thesis.
