Annual energy savings <br /> equate to heating 16,300 homes. Estimated emissions <br /> reductions of 0.0170 million metric tons of carbon <br /> equivalents. <br />LMOP Partners Allied Waste Services, CPL Systems Inc., Tennessee <br />Involved Department of Environment and Conservation <br />Who wants. to pay high natural gas <br />prices? Not the largest of The Solae <br />Company's food-ingredient <br />manufacturing plants. Solae invested <br />several iiiiiilon doiicarS to reCOnfigt.ire itS <br />soy-based food ingredient plant in <br />Memphis to burn landfill gas (LFG) in <br />three boilers, thus taking advantage of <br />a renewable energy source and <br />displacing nearly a quarter of its <br />natural gas consumption. <br />To make the project work, Solae <br />formed apublic-private partnership <br />with Allied Waste, Memphis Light Gas ~ <br />and Water (MLGW), and CPL <br />Systems. The project took only one year from proposal to startup. CPL Systems worked <br />with Allied Waste to increase gas recovery at Allied's South Shelby Landfill and automate <br />control of LFG between the flares and the pipeline. MLGW did its pan` by installing a 5-mile, <br />12" HDPE line in just 91 days. <br />The project's highlights include the following: <br />• Blowers and gas control equipment rated at 5,000 scfm and designed to handle <br />increasing LFG flows over the next 25 years. <br />• Real time process, equipment, and LFG utilization data are available through a <br />computer-control system for monitoring and off-site correction. <br />• Continuous control equipment adjusts the flow of LFG to the boilers, seamlessly <br />transitioning fuel flow in as little as 30 seconds. <br />• Nitrogen oxides reductions of 75 percent. <br />http://www.epa.gov/landfill/proj/prof/profile/solaedirectuseproj ect.htm <br />6/8/2009 <br />~''. <br />~~ <br />
