Acceleration of Landfill Stabilization Using Leachate Recycle
Publication: Journal of Environmental Engineering
Volume 122, Issue 4
Abstract
A leachate recycle system was constructed and operated at an existing lined landfill in North-Central Florida to observe the effects of leachate recycle on landfill stabilization. Samples of leachate, landfill gas, and landfilled solid waste were collected and analyzed throughout a four-year period, before and after the start of leachate recycle. The settlement of landfilled waste was also measured in wetted and dry areas of the landfill. Leachate quality was not dramatically impacted by leachate recycle. Moisture content was significantly greater in the area of the landfill subjected to leachate recycle. Waste temperature and pH measurements indicated that conditions suitable for anaerobic decomposition were present in both the treated and untreated areas. Measurements of solid waste biochemical methane potential and subsidence showed that a greater degree of landfill stabilization had occurred in the leachate recycle area relative to the untreated area.
