Utilization of Industrial By-Products for Construction Materials
The United States is a major producer of agricultural, industrial, mining, and municipal waste materials in the world. Traditional methods of waste disposal most often have resorted to...
Keller Canyon Fills a Need
Opening a new landfill site in California can be an onerous task. Any owner willing to try must work with the state's stringent environmental legislation, profusion of solid...
Exchanging Wastes
For several years, thousands of cubic yards of dried sludge have been stockpiled at the Greater Peoria Sanitary District's wastewater-treatment plant in Peoria, Ill., because...
Runoff As A Resource
Recent studies have shown that storm-water flows from urban and industrial areas typically contain significant quantities of the same pollutants found in wastewater and industrial discharges....
Engineering Sustainable Development
Despite some isolated environmental victories in the past few decades, on a system-wide level the problems�from acid rain to destruction of the rain forest�are getting worse. Can humanity...
Geosynthetics Conquer the Landfill Law
Los Angeles' last operating landfill is undergoing a major expansion using innovative materials in the liner system to overcome difficult site conditions. The design represents...
Roller Compacted Concrete Tailing Retention Dam
A roller compacted concrete (RCC) dam has been designed for gold tailing impoundment in southeast Alaska. To minimize up front capital costs, the curved gravity dam with multiple outlet...
