Abstract
Analytical methodology to estimate the spatial distribution of resource and energy demand at an individual building level was developed. By using the method, the present study addressed a potential impact of installing a biogas plant in respective premises of the wastewater treatment plant in Kawasaki city. As a result of 8 collection scenario, the separate collection and the utilization of organic food biomass from municipal solid wastes yielded the maximum energy recovery by 30 GWh/year (electricity) and 75TJ/year (heat), and CO2 reduction by 12000 t-0O2/year. The methodology with high spatial resolution also enabled a tailor-made analysis and discussion, addressing building-scale energy demand-supply relationships, and improvement of lower heating value in the incinerators, which could be valuable inputs to the urban environmental management practice and policy making.
