摘要：Rigid polyurethane foam (RPUF) is used as thermal insulation, especially in a refrigerator. Afterthe refrigerator was discarded, it was dismantled by the dismantler. Most of the time, RPUF wastewas found illegally disposed or openly burned, causing environmental problems and human healthissues, owing to reckless management. Therefore, RPUF waste is one of the most concerningwaste disposal, leading to this study. This study investigates on RPUF waste started from thebeginning of the cycle, which was the chemical production, to the end of the cycle, followed bythe dismantling site. The result revealed that the blowing agent, for example, HCFC-141b, HFCs,and cyclopentane, was added in a foam production process for refrigerator, an amine group wasadded as a catalyst and a flame retardant was not added in the RPUF used in the refrigerator. Thestudy was collected survey from the dismantling sites in 5 regions of Thailand (19 dismantlingsites). These indicated that the disposal options of the RPUF wastes were landfill (47.83%), openburning (21.74%), sanitary landfill (13.04%) incineration (13.04%) and refuse-derived fuel or RDF(4.35%), respectively. Landfill presents the main disposal method for RPUF waste in Thailand. Forenvironmental aspect, in 2018-2031, the landfill disposal will affect the environment in terms ofglobal warming 22,175.36-39,290.65 kg CO2 eq/yr, ozone depletion 0.015-0.027 kg CFC11 eq/yrand terrestrial ecotoxicity 52,098.17-92,308.34 kg 1,4-DCB/yr.
