MMC's slow-fill CNG station refills trucks overnight and can accommodate up to 15 trucks. success story MMC Materials Converts to Compressed Natural Gas Angelle Bergeron M MC Materials, Inc. invested $1.5 million last July to convert one of its Jackson, Miss., fleets of ready mix trucks from diesel fuel to compressed natural gas. The company anticipates it will take about 60 months to recover its full return on investment. However, MMC is already reaping the environmental and safety benefits, the satisfaction of decreased dependence on foreign oil and several unanticipated benefits, including the good will of employees, the industry and the community at large. "I can't think of any downsides to it," said David Bosarge, MMC's safety and environmental manager, who spearheaded the effort to switch. MMC, a family-owned business since 1927, strongly supports environmental operations and safety, said Bosarge, who was encouraged in late 2011 to pursue the CNG conversion as a cleaner environmental alternative to diesel. "We're always looking for ways to improve our operations," he added. "Taking one diesel fuel operated concrete truck off the road is equivalent to removing the emissions from about 100 cars and pickup trucks that run on gas and diesel fuel." The switch to CNG aligns perfectly with the company's motto, "Honesty, Excellence, and Continuous Improvement," said Stanley Mangum, vice president of MMC's Central Mississippi division. "We think this conversion is an improvement not only to our business, but to our industry, and the economy as a whole. If we ran every heavy truck in the ready mix industry on natural gas, think about how much that would reduce U.S. dependence on foreign oil." Using domestic fuel "helps our state, community and nation," said Rodney Grogan, president. "It's an environmentally good thing to do, will help provide jobs in this country, and in the long term, we anticipate seeing financial benefits." The Price is Right Natural gas as a transportation fuel started gaining momentum nationally in recent years when the discovery of recent shale plays created a huge price separation between natural gas and oil, said Bob Kerley, vice president of marketing for the Mississippi division of Atmos Energy, the largest natural gas provider in the state. Natural gas has environmental appeal because it is the cleanest burning fossil fuel available, Kerley said. "As compared to diesel or gasoline, the use of natural gas can reduce greenhouse gases significantly since it emits about 80 to 90 percent less carbon monoxide, 25 to 30 percent less carbon dioxide and 90 percent less nitrogen oxide." Despite those benefits, it takes a certain type of company to make the switch to CNG, Kerley said. "You've got to have somebody who is open to change and is willing to test the waters, so to speak, and look at new technology in ways that would help their business," he said. "You've got to be innovative and have a vision for what your drivers are. For MMC those drivers are the environment, safety and cost savings." To Kerley's knowledge, MMC is the first ready mix concrete company in the southeast that has ventured into CNG conversion. "There are doubters out there who think it's not worth the investment and it takes too long to get a return," Grogan said. "We're always looking for continuous improvement, concrete INFOCUS ı 11
