Written by Paul Stout Although some projects came before financial incentives, the Internal Revenue Service Section 29 tax credits helped usher in the large wave of landfill gas (LFG) to beneficial use projects of the late 1990s. Electrical deregulation and the requirement for electrical providers to have a certain amount of green power in their portfolios helped keep things going, at least in some areas, in the new millennium. More recently, Section 45 tax credits have helped many continue the LFG...... continue reading

Written by Tom Bilgri and Steve Wittmann In the solid waste industry, we sometimes focus too intently on what happens within the fence line, and fail to pay enough attention to what goes on outside, especially when it comes to transport and delivery of landfill gas (LFG), whether for onsite use or transported to a third-party. The new provisional standard, NFPA 56 (PS), Fire and Explosion Prevention During Cleaning and Purging of Flammable Gas Piping Systems, issued by the National Fire Protec...... continue reading

Written by Neal Bolton You bet, and an ever-increasing number of landfills are taking advantage of it. It’s a simple process really—and quite natural. Organic material—which is rich in carbon—is decomposing. And in the process, methane and carbon dioxide are created. Even though this is a natural, commonplace process—methane is perhaps the most common organic compound on the planet—most of it has nothing to do with landfills. What’s happening in your landfill is a small example of what’s happening ...... continue reading

Written by Ed Ritchie Not long ago they were open trash pits that emitted unpleasant odors while devouring the financial resources of their owners. But today, it’s as if the princess of sustainability came along and kissed the frog of landfills, and now the frog generates profits rather than odors. But don’t blame the turnaround on magic. Instead, look to the technology of landfill-gas-to-energy (LFGTE) production. With more than two decades of history and a well-developed marketplace in Europe, t...... continue reading

By Nina Danza and John Hancock In mid-2011, a new state rule exploded the number of hours needed to perform surface emissions monitoring at Tajiguas Landfill, a large public regional facility in Santa Barbara County, California. Previously under only the federal New Source Performance Standard (NSPS) rule, the landfill started compliance in the summer under a second surface-emissions rule set forth by the state. Before the new requirements, about three days per quarter were needed for ...... continue reading

It’s not quite the Mr. Fusion from Back to the Future II , but Rumpke of Ohio’s newest fleet of garbage trucks does indeed run on garbage. The Cincinnati-based landfill operation invested $2.3 million along with an $800,000 grant from Clean Fuels Ohio in order to put 10 new compressed natural gas (CNG) trucks on the street last August. The grant was part of the original, national stimulus package. The project includes the CNG-powered refuse collection trucks and the construction of a natural-gas fueling...... continue reading

I remember with great clarity going to USEPA’s landfill methane outreach conference (LMOP 2003) in Washington, DC, where I listened with genuine astonishment to presentation after presentation that came to what, at the time, was the somewhat unexpected conclusion that the future for landfill gas was more than good…it was hot! Keep in mind that these were presentations to an audience composed of people who had grown ancient watching various governmental bodies hem and haw over how to deal with political,...... continue reading

Estimates of landfill gas (LFG) emissions made by the EPA and the Intergovernmental Panel on Climate Change have suggested that landfills are a significant source of man-made methane emissions, ranking 3rd in the US behind natural gas systems and ruminant digestion (interpreted as cow flatulence). Given methane is 25 times more potent as a greenhouse gas than carbon dioxide, its more familiar accomplice in global warming, determining how much methane comes from landfills is important in demonstrating ho...... continue reading

Polishing up my crystal ball and peering into the future, as well as looking over my shoulder at the history of this industry, I’m reminded that this is a relatively young industry compared with most—we’ve really only been part of the solid waste landscape since the 1970s. The pioneering days of Scholl Canyon, Palos Verde, and Sheldon Arleta led us into this industry, and we were subsequently propelled along by Getty Synethic Fuels, the Resource Conservation and Recovery Act (RCRA), Subtitle D and the F...... continue reading

One of the main issues associated with the proper construction, operation, maintenance, and closure of an MSW landfill is how to manage the landfill gas over the operational lifetime of the landfill and throughout its post-closure care period. Small, older landfills and landfills with minimal organic content—particularly those in which periodic burning was part of the operational process—can often get by with just a series of passive vents installed around the landfill’s perimeter to prevent the offsite...... continue reading
