5. Materials Revenues. Ferrous metals can be recovered from the bottom ash <br />and sold as scrap on the open market. It was assumed that 2 percent of the <br />incoming waste or 1,752 tons per year would be recovered and sold at a <br />current price of $80.00 per ton. It was assumed that the plant operator <br />would receive 50 percent of the sales as an incentive payment, a standard <br />industry practice. <br />6. Operating Costs. A cost of $57.00 per ton processed was assumed for the <br />analysis. <br />5.1.3 Pro Forma Operating Statement <br />Based on the assumptions above, the annual Operating Statement of the system <br />would be as presented in Table 5 -1. <br />Table 5 -1. Pro Forma Annual Operating Statement <br />Revenues <br />Costs <br />Electricity $1,839,600 <br />Ferrous Recovery $140,160 <br />Total Revenues $1,979,760 <br />Operating & Maintenance <br />Ash Disposal <br />ByPass Disposal <br />Annual Debt Service <br />Operator Revenue Sharing <br />Total Costs <br />$4,993,200 <br />$1,095,000 <br />$660,000 <br />$3,991,076 <br />$183,960 <br />$10,923,236 <br />Net Cost $8,943,476 <br />Net Cost /Ton $102.09 <br />The ash produced by the facility would need to be transferred and landfilled. The <br />estimated cost for this is projected at $50 per ton in Table 5 -1. <br />The cost per ton is quite sensitive to the price of electricity. For example, if it could <br />be assumed that electricity could be sold for $0.09 per kilowatt-hour instead of $0.06 <br />per kilowatt-hour, the net disposal cost of approximately $102 per ton would be <br />reduced to $89 per ton, an approximate 13 percent reduction in cost. <br />5.2 Effectiveness of Waste Processing Technologies <br />Since any WPT will have some residual in need of disposal, when discussing <br />effectiveness of a WPT, emphasis is placed on obtaining the least amount of residual <br />material for final disposal. While combustion technologies significantly reduce the <br />volume of material destined for landfills, the resulting ash must be managed. Typical <br />management methods include disposal in a Subtitle D landfill or beneficial use in <br />construction projects and alternative daily cover for landfill wastes. In Europe, <br />where land for landfilling is scarce and several countries have banned landfills, the <br />GBB/C08027 -01 25 August 15, 2008 <br />
