Abstract
In this study, we analyzed the effect of GHG reduction by utilizing various sewage sludge fuels based on collaboration among sewage infrastructures, industrial infrastructures, and domestic waste incinerations from 2020 to 2030. First, we estimated the amount of un-utilized sludge, and acceptance capacity of sludge fuel at industrial factories and municipal incinerators. Then, GHG reduction effect was analyzed with respect to GHG inventory of fuelization technologies and allocation rules of sludge fuel. As a result, it was revealed that this collaboration could recover energy from 87.3% of un-utilized sewage sludge, and reduce 3,320 thousand tons of carbon dioxide at most. In addition, the effect of GHG reduction influences amount of production of industrial infrastructures in future and mixed combustion ratio in pulp industry.
