With the advent of the era of higher oil price, the necessity of developing new and renewable energy source has greatly increased as a countermeasure. Therefore, as well as the reduction of greenhouse gas emission, waste to energy concept has internationally emerged as leading means of new and renewable energy currently. In specific, it has been demanded to develop alternative energythrough making use of landfill gas to create a plan of economically and environmentally viable for landfill gas utilization. This study investigated a disposal and recycling technology of high concentration desulfurized sludge and leachate, being produced in the preprocess of landfill gas. After mixing the leachate containing high concentration sulfur and desulfurized sludge with metal plating wastewater, feasibility of removing and recovering heavy metal and sulfur was examined. Heavy metal contained in metal plating wastewater removed up to about
77% average, showing relatively high yielding rate of possibility of removing heavy metal and sulfur through sulfur- heavy metal interaction.
