Abstract
In this research, GIS database was developed to support the circulation scenarios of municipal solid wastes in Kawasaki City. To determine new waste collection boundaries, disaggregate spatial database of 1km grids for household and business general waste was developed. Transportation network was applied to determine collection boundaries of treatment facilities with shortest transportation distance.CO2 emissions of circulation policy scenarios from the transportation process, the operation of new existing treatment facilities, and CO2 emission reduction effects from circulation of organic wastes were calculated.
