Energy recovery from polyalkylene terephthalate materials, especially photographic film, comprises burning the materials in the presence of catalytic amounts of heavy metal compounds

摘要

Energy recovery from polyalkylene terephthalate materials comprises burning the materials in the presence of catalytic amounts of one or more heavy metal compounds. Energy recovery from polyalkylene terephthalates of formula (I) or materials containing them comprises combustion in the presence of catalytic amounts of one or more heavy metal compounds: R = ethylene, propylene, butylene or 1,4-cyclohexanedimethylene.
