Changes in geotechnical properties of Municipal Solid Waste (MSW) in bioreactor landfill with degradation
The objectives of the research described in this paper are to: study the composition of fresh Municipal Solid Waste (MSW); study the effects of decomposition on physical characteristics of MSW in bioreactor landfill. Initially, composition of the fresh MSW constituents was determined based on 14 bag MSW samples. Then, four small-scale bioreactor landfills were simulated in laboratory and samples were prepared to represent each phase of decomposition. Laboratory tests were conducted to determine the changes in physical characteristics (moisture content, organic content, specific gravity, density and permeability) of MSW at each phase of decomposition and presented in this paper.
