| Research Abstract |
In this study, the advantages in environmental impact and health effect of bio-oil from sewage sludge and kitchen garbage, which can be used as a fuel for direct combustion with natural gasses and heavy oils, was evaluated in terms of energy consumption and greenhouse gas (GHG) emissions, and population exposure to NO_x. The results of analysis targeting Osaka City showed that about 50% of GHG emission reduction could be achieved through the introduction of disposer into kitchen garbage collection system and pyrolysis technology to produce bio-oil into sludge incineration process. In addition, we found that the population exposed to more than 0.1mg/m^3 of NO_x would not increase when the mixed heavy fuel oil would be combusted with 5% of bio-oil mixture ratio.
