The waste discarded from ordinary homes is incinerated using heavy oil at high temperatures. However, despite the depletion of fossil fuel resources and concomitant atmospheric pollution associated with the combustion thereof, we continue to incinerate garbage using heavy oil. Given the deleterious impact that this has on the global environment, the incineration of household waste should be stopped. Instead, we should consider ways in which garbage could be used as a resource and recycled. However, the salinity content of household waste is another potential environmental problem, particularly when the household waste composted during drying, and a method for ameliorating this high salinity therefore needs to be developed. We developed a method for removing the salinity from household waste in water. In order to prevent the generation of unpleasant or offensive odors during treatment, it is important that the household waste not be permitted to decay. We therefore used titanium dioxide supported in silica gel a photocatalyst to prevent the anaerobic/aerobic digestion of household waste. By using the photocatalyst in combination with a decomposition tank, we were able to develop a method for removing the salinity from the household waste.
