Estimate for waste generation from future building demolitions

摘要

Estimation methods of waste generation from building demolitions were examined, and demolition waste generations in the near future (including hazardous wastes) were estimated in Japan as a whole. Conclusions are as follows: 1) estimation methods of building demolition corresponding to existing statistics data and changes in building life span were improved; 2) statistics values for wastes from building demolition could be underestimated; and 3) demolition waste generation was estimated to be doubled in 2010 as compared to those in 1990, with generation from non-wooden buildings being larger than those from wooden buildings due to the increasing generation of concrete waste, and CCA-impregnated wood and vinyl chloride wastes will increase rapidly, estimated to become 3 times in 2010 as much as those in 1990.
