Abstract

|
Most of municipal waste generated in korea has been treated in 9 major stocker-typed incineration plants with design capacity greater than 200 tons/day where the amount of waste incinerated amounts to 682,820 tons from January to December 1997. If total costs of approx. 28.1 billions Won for operation and maintenance of 9 incineration plants for 1997 were taken into account, if would cost about 41,135 Won per ton of waste incinerated. And it was found that treatment cost for waste per ton may be lowered much more by revenue from electricity and waste heat sales, and reducing environmental costs through a cost-effective treatment of incineration ash. It is showed that annual operating costs are in proportion to capacity of incinerators, while treatment fee for waste per ton is in inverse proportion to that. And it is indicated that treatment cost per ton would be affected much more by capacity of incinerators than their types. It is concluded that the incineration plants with EP, W/S and SCR require much more operating costs than those with SDR, EP and W/S, while treatment fee for waste per ton in the former plants is cheaper than in the latter.
