GENERATION AMOUNT PREDICTION AND RECYCLING FEASIBILITY ASSESSMENT OF USED SANITARY CHINAWARE WASTES

摘要

The recycling rate of mixture of construction waste is at a greatly low level. Especially, the sanitary chinaware wastes are almost disposed by landfill because of lack of effective reuse method. To explore the feasibility of recycling of sanitary chinaware waste, the generation amount of sanitary chinaware wastes from 2003 to 2020 in Kitakyushu was predicted and the cost and LCCO_2 for separating and recycling was assessed in this paper. The generation amounts of sanitary chinaware wastes were separately estimated by source from dismantlement of wasted building and source from extension and redecorating of existing buildings. Probabilistic assessment for separating and recycling was executed based on the following assumptions: generation rate of sanitary chinaware waste is 40 tons per month; separating and recycling facility locates in Wakamatsu-ku; recycling products are aggregate of concrete, permeable block and mixture material for plastic.
