Solid Waste Management Case Studies

Case Study of Leachate successfully treated by Trinity International

MSW Dumping site

Leachate can be defined as a liquid that passes through a landfill and has extracted dissolved and suspended matter from it.
Leachate generation is a major problem for municipal solid waste (MSW) landfills and causes significant threat to surface water and groundwater
