Recently, detections of huge amount of wastes in the unsanitary landfills at a residential development sites were reported. Because the sites were the residential development sites, all landfilled wastes should be removed for the constructions. Therefore the way that the unsanitary landfills were excavated and then the wastes were sorted into three categories such as soils, noncombustibles, and combustibles was selected as the best method. Soils and noncombustibles could be recycled in the sites and combustibles could be compacted and be relandfilled in a smaller area.

Characteristic of wastes in a unsanitary landfill at the residential development site in H city, Kyunggi-do was investigated for the disposal of huge amount of wastes. The total amount of wastes was estimated at 117,000 ton and construction solid wastes and municipal solid wastes were detected together. The portion of combustibles was very low and soils, concrete wastes, and pebbles were the major components in landfilled wastes. Because the site was the residential development site, the landfilled wastes should be removed immediately for the construction. Therefore the way that the unsanitary landfill was excavated and the wastes were sorted into three categories such as soils, noncombustibles and combustibles was selected as the best method. Soils and noncombustibles could be recycled and sorted combustibles could be re-landfilled in a smaller area or incinerated.
