As the public grows increasingly leery of siting new landfills, the choice to extend the service life of existing landfills is becoming more appealing to solid waste managers. When landfill operators cover the garbage over with dirt each day, the material consumes as much as 30% of landfill capacity. In the session Extend Landfill Life with Alternative Daily Cover and Other Applications (Monday, Sept. 11, 11 to 11:50 a.m.), Jose Gamboa—superintendent of waste disposal for Santa Cruz, Calif.—will share a variety of methods to increase a landfill's useful life, including replacing dirt with tarps, applying a thin layer of cement, and increasing the density of refuse per cubic yard. “By implementing several techniques to extend landfill life,” says Gamboa, ”it gives science and technology time to develop methods and systems to deal with the problems of solid waste in a more environmentally benign and cost-effective manner.”
