Abstract

This research worked on the measure against CO2 reduction according to the characteristics of the area for the Kanazawa seaside area in Yokohama city. This area consists of a collective housing complexes and a minor scale industrial complex; and also locates a waste incineration plant; a wastewater treatment plant; and a sludge treatment facility. Having been chosen as a measure with the large amount of CO2 discharge reduction; it is the system which feeds into an incinerator the methane gas by carrying out mixed digestion of the kitchen garbage together with sewer sludge; and supply heat from a waste incineration factory through the transmission line. However; since this system has large initial cost for construction of transmission line; marginal abatement cost (MAC) for CO2 emission reduction is very as large as 166.16 [USD/CO2]. Then; when the pay-back year of the transmission line was changed from 20 years to 31.5 years which is equivalent to 70% of legal durable years; MAC was reduced to 104.40 [USD/CO2]. Moreover; when Non Energy Benefit (NEB) by system introduction; such as job creation and an environmental improvement of the area; was taken into consideration; MAC was greatly reduced to -124.22 [USD/CO2].
