Photograph courtesy of ACF Environmental A critical component of a well-conceived waste management plan, landfills are highly engineered facilities. In particular, the design and management of municipal solid waste (MSW) landfills carry environmental significance. The site, design, construction and operation of landfills require stringent compliance with government [...]
Mining tailings management with geosynthetics
Tailings are by-products, the materials that remain after the process of separating the target mineral from the uneconomic fraction of an ore. They are different from the waste rock or other material that overlies an ore or mineral body, which are displaced during mining without being processed. Tailings can be liquid, solid or a slurry [...]
CETCO’s new RESISTEX Universal GCL Series unveiled
