Seven major, mega-landfills were developed in the 1990's in Amelia, Brunswick, Charles City, Gloucester, King and Queen, King George and Sussex counties. Facilities accepting at least accepting 3,500 tons of municipal solid waste per day are often called "mega-landfills."1
An eighth mega-landfill has been proposed several times for Cumberland County. Despite approvals by local officials, no construction occurred before another proposal received approval in 2018. The company that proposed building the Green Ridge Recycling and Disposal Facility in Cumberland County had been paying competitors to use their landfills, such as Waste Management in Amelia County.1
Some of the waste placed into mega-landfills is generated in Virginia, and some is imported from out-of-state.
