by Therese Dunphy, Editor-in-Chief We've combed through 20 years of stories about operations to extract ideas that can make your plant more effi cient — and profi table. 1 The BoDean Co.'s Mark West Quarry installed solar panels at its site, beginning by providing power to its offi ce building. In 2011, it was able to run the entire plant on power generated from the solar array. 2 Vulcan Material Co.'s Huntsville Quarry runs its plant from early morning until early afternoon to achieve signifi cantly lower electricity rates. Its scales, however, remain open for customers during standard work hours. 4 Martin Marietta's Arrowood Quarry built 80-foot-wide haul roads to accommodate the trend toward larger haul trucks. It also uses 4- to 6-inch-thick rubber bedliners to extend the service life of their haul trucks by an estimated 15,000 to 20,000 hours. 6 Rogers Group color-coded the two motor control center buildings at its Pottsville Quarry to streamline maintenance. 3 Operating in a water-sensitive area of Texas, Summit Materials' Nehemiah Pit invested in dry dust sup- pression equipment to minimize dust while reducing water use. The system consists of sealed convey- ors and dust collectors. 5 By working with experts to retrofi t equipment, Luck Stone has implemented the use of remote-con- trolled wheel loaders to safely access additional reserves and is developing autonomous haul trucks that will allow one driver to lead a fl eet of trucks through the load-haul-dump-return route. 21 Operations ideas to maximize profi t per ton 30 Six steps to keep hydraulic hammers going 36 MSHA circumvents regulatory review Sustainability October 2011 www.AggMan.com Sustainability Sustainability Strategies cover_use_no box_AGRM1011.indd 1 9/26/11 5:09 PM AGGREGATES MANAGER / March 2016 13
