Proposal of new waste removal simulation model for remedial planning at illegal dumping sites

Abstract

Recently, a problem on large-sized illegal dumping sites has been serious. The dumped waste has been often removed and treated thermally. But because of limitation of capacity of treatment facilities and cost, dumped wastes removal planning considering pretreatment is important to remedy the illegal dumping sites. In this study, a waste removal simulation model was developed considering pretreatment of hazardous wastes to reduce risk. In special, simulation of waste removal was conducted to predict amounts of hazardous and non hazardous wastes to be treated a day, and period for removal of all dumped wastes. As a result, pretreatment of hazardous wastes decreased the amount of hazardous wastes to be treated, and it contributed stable operation of waste removal, which decreased period required for remediation of site.
