Municipal waste was to evaluate the composition of the landfill waste in this study. As a result, the percentage of the remaining incineration increased from around 1980, in the 2013 year is in the whole of 73%. Metal waste is contained many direct disposal waste 1988-1995 around, and has been estimated to account for 12-14% of landfill waste.
Then, Landfill waste was evaluated and the CO2 emissions recycling possible amount of landfill waste on the assumption that recycling in the cement resources and melting process.
Combustible waste (Other than waste plastic) was excluded from the assessment to decompose in the landfill site.
As a result, until 1970 and 1990, landfill waste per tonne, is recovered about 800kg. is recovered, the breakdown of cement resources (incineration waste) 35-50%, metals 13-25%, the molten slag 34-40%.
CO2 emissions for recycling was 510-639 kg-CO2/ton until around 2000. The increase of the remaining incinerated in recent years, there is a possibility to significantly decrease.
