5' Materials Revenues. Ferrous metals can be recovered from the bottom ash and sold as scrap on the open market' It va sassumed that 2 percent ofthe incoming waste or 1,752 tons per year would be recovered and sold at a current price of $80,00 per ton. It was assumed that the plant operator would receive 50. percent of the sales as an incentive payment, a standard industry practice. G. Operating Costs. A cost of $57.00 per ton processed was assumed for the analysis. 5.1.3 Pro Forma Operating Statement Based on the assumptions above, the annual Operating Statement of the system would baas presented in Table 5-1' Table 5-1.

T� estimated produced is projected at $50 per ton in Table 5-1' The cost per ton is quite sensitive to the phma of electricity. For example, if|tcould be assumed that electricity could ba sold for $O,O9 per kilowatt-hour instead of¢O.OG per kilowatt-hour, the net disposal cost of approximately $102 per ton would be reduced to $89 per ton, an approximate 13 percent reduction in cost. 5~2 Effectiveness of Waste Processing Technologies Since any VVPT will have some residual in need of disposal, when discussing effectiveness of VVPT/ emphasis is placed on obtaining the least amount of residual material for final disposal. While combustion technologies significantly reduce the volume of material destined for landfills, the resulting ash must be managed. Typical management methods include disposal in a Subtitle D landfill or beneficial use in construction projects and alternative daily cover for landfill wastes. In Europe, where land for|andfi||ing is scarce and several countries have banned landfills, the GBB/CO8027-01 25 August 15,2OO8
