Current Conditions and Tasks at Landfill Sites Handling Municipal Solid Waste

Abstract

Although emissions of municipal solid waste are decreasing year by year, it is difficult to construct new landfills due to the fact that permission from stakeholders is hard to obtain. The high amount of municipal solid waste from Saitama Prefecture is actually disposed of in another prefecture. Incinerated ash had been the main product being disposed of at landfills, but its recycling rate has currently increased due to technologies being employed by cement companies.
On the other hand, the recycling rate of crushed residues, another major project being disposed at landfills, has not progressed. Under the current conditions, in order to reduce landfill waste, it will be necessary to investigate and study the current status of the incombustible trash processing system.
