SOLUTIONS FOR CHAPTER 9 9.1 Analysis of the recycling rates using Table 9.8 data and prices from Table 9.18 a. Carbon savings is 747MTCE b. At \$50/ton, tipping fee savings is 936 tons/yr x \$50/ton = \$46,800/yr c. Revenue generated is \$118,845/yr d. With a carbon tax of \$50 per metric ton of carbon-equivalents, savings due to recycling would be 747 MTCE/yr x \$50/MTCE = \$37,350/yr 9.2 Analyzing the energy side of the airport recycling program described in Problem 9.1 using Table 9.9 a. Annual energy savings is: 21,494 million Btu b. At \$5 per million Btu, the dollar savings is 21,494 million Btu/yr x \$5/million Btu = \$107,470/yr c. Dollar savings per ton would be: \$107,470 / 936 tons = \$114.81/ton 9.1
