The objective of this study is to analyze appropriate sizes for incineration facilities to minimize the social cost of disposing waste, and to determine improvement plans for waste management policies.
Incineration is a desirable method of waste disposal in Korea, as the problem of secondary pollution is solved with the development of clean technology. It is a core policy of the Department of the Environment to maximize the use of incineration.
Total cost declines as the size of a facility increases, until a certain size is met. Therefore, the appropriate size is estimated. The result of estimating the total cost of installation and operation of incineration facilities based on future waste generation and disposal showed that large incineration facilities (400 tons per day) is more efficient in large cities. In other areas, the 100-200 ton per day facilities are more cost effective. The total incineration cost per waste unit ranges from KRW 60-200 per kilogram regionally, with a national average of approximately KRW 100 per kilogram.
The policy implications of waste management policy in Korea are as follows: first, privatization of incineration facilities should be implemented to promote the effective installation and operation of facilities, collection, and transport of wastes by one company. Second, since the waste disposal service is not a public good, each household should contribute to its cost and the price for the garbage disposal bags should be increased. Third, the current system, in which the disposal of the wastes is linked to administrative districts, should be abolished, and the waste management districts should be reorganized based on the appropriate sizes of each district. Fourth, the recycling of flammable and inflammable wastes should commence. The finances consumed for waste management in the next eight years exceeds KRW 10 trillion, and large parts of this budget are prospected to be invested in the construction of incineration facilities. Therefore, more effort should be made to minimize this cost.
