Owing to the development of sewage treatment system as a countermeasure for daily waste water, the amount of sludge generated in sewage treatment facilities has been increasing, and it becomes more difficult to find enough landfilling site. Carbonization technology of sewer sludge attracts a great deal of attention as one with promising sewer sludge processing technology. Then, usage of carbide is an important equation. Recycling use at municipal solid waste system is raised as one of the uses of carbide. Here, We examined on effective use of carbonized sewage sludge in municipal solid waste system. This paper describes the effect as a deodorant, the facilitatory effect of the precipitation in a gravity thickener, the gas evolution facilitatory effect in methane fermentation processing, the removal of water effect of sludge, and the effect at the time of membrane processing.
