Greentree Landfill is an MSW landfill and Permitted Centralized Treatment Facility that was permitted in 1986. The facility was most recently expanded in 2008. The facility is permitted by the Department of Environmental Protection to accept 5500 tons per day average and a maximum of 6000 tons in any single day. The facility currently accepts 3000 tons per day average. Municipal Solid Waste, Construction and Demolition Debris, Municipal and Industrial Sewage Sludges, non-hazardous liquid waste, asbestos, and residual wastes are received for disposal. The facility is permitted to accept liquid wastes for solidification. Additional services include non-hazardous liquids treatment and disposal, trailer and roll-off container storage. The facility offers trailer tipper service to unload intercompany and third party trailers. At current volumes the facility has airspace to 2048.
Greentree Landfill has a high Btu gas cleaning plant onsite operating since 2007. Currently, we are treating about 6,500 cubic feet per minute of landfill gas. After the cleaning process, about half of the landfill gas is sent down a 6.5-mile pipeline to a compressor station where it is tied into the National Fuel Interstate pipeline where it is sold as Green Power to power plants.
The facility is included in several County Solid Waste Plans, and has contracts with residual waste generators both in PA and surrounding states and accepts waste from Advanced Disposal subsidiaries and third party companies.
