By Don Talend Landfill grading, and cross-slope grading in general, poses a unique challenge for automated grade control technology: that of holding grade by accounting for cross-slope dozer blade angle. A New York contractor that was awarded the contract to cap a landfill on Long Island, NY, recently employed an automated grade control system that suits cross-slope grading and maximized dirtmoving efficiency on a site that represented anything but an ordinary cut-and-fill project. Capping the 28-acre L...... continue reading

Written by Ed Ritchie “The worse the route or driver behavior, the more effective the system, because it doesn’t allow the driver to abuse the truck.” —Scott Kanne, Wayne Engineering “There is a trend in developing hydraulic, battery, and ultracapacitor hybrids, and the regulatory agencies want to understand the technologies and their impact on emissions.” —Andrew Burnette, InfoWedge The market for hybrid-drive refuse vehicles is gaining momentum as more municipalities comple...... continue reading

Written by Neal Bolton All landfills are similar; but then again, they aren’t. Some landfills are simply more efficient and more competitive than others. One important characteristic of a competitive landfill is the ability to use airspace effectively—important because it results in reduced operating costs, deferred capital costs, and a more competitive bottom line. Sure, there are variations in wastestream, site conditions, local weather patterns, and other important criteria, but after filtering throu...... continue reading

Written by Carol Brzozowski When it comes to increased market development for recycled materials, those who coordinate municipal recycling efforts would like to see more information sharing, a greater demand for recycled products on the back end, and more collaboration between the product packaging industry and recyclers. Ultimately, what each municipality decides to recycle depends on the marketability of that material as a recycled product. In Milwaukee, WI, recyclables are collected by the munic...... continue reading

Written by Pat Proano Our cities and counties, including the County of Los Angeles, continue to be recognized for excellence and achievement in the restoration of multiuse ecosystems and the development of sustainable capital projects that consistently earn Leadership in Energy and Environmental Design (LEED) certification. We have become master recyclers and maintain some of the highest recycling rates in the nation. In Los Angeles alone, we recycle nearly two-thirds of our trash. But despite this...... 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 Daniel P. Duffy A poker player down on his luck can always ask for a new deck. Shuffling that new deck can help break a string of bad luck and give the player a winning hand. The recycling industry has been dealt a bad hand since the financial meltdown of 2008. It has been hurt more than most industries by the economic down turn of the past few years. Demand has slackened and the market prices of recycled materials have crashed. Stockpiles of metals, cardboard, plastic bottles, and alumi...... continue reading

Written by John Trotti This past fall I spent a day getting my few remaining grey cells whipped into confusion by attending a seminar on what’s happening in the world of digital wizardry, and while there was a lot of food for thought, I came away with no fuzzier feeling for the situation than before. True to our penchant for change, new machines, operating systems, peripherals, and expectations joined in the race to somewhere, but it was not until 1979 we were to find out where when what many refer to a...... continue reading

Written by Lori Lovely When 200 trucks a day spent so much time on the scale that the Collier County, FL, landfill had to extend hours to accommodate them, the management knew it was time for a change. In addition to weighing trucks coming in and out for billing purposes, hazardous waste is tracked. The Collier County landfill, which serves more 253,000 residential accounts, is a full-scale operation handling residential MSW garbage, most of it hauled by Waste Management, although mom-and-pop colle...... continue reading
