Abstract
Kitchen waste refers to waste which is degradable and with high content of organic matter such as lettuce, flesh, peels, etc. Kitchen waste is more easily degraded than non-kitchen waste and produces a greater amount of leachate and landfill gas. It is vital to study the consolidation of municipal solid waste landfills with high kitchen waste content. A new consolidation model for unsaturated high-kitchen-waste-content MSW is proposed after summarizing the consolidation model for unsaturated porous media and high-kitchen-waste landfill.
The model takes pore gas pressure and matrix suction as variables. The model is based on hydro-mechanics coupled model for unsaturated porous media, taking bulk modulus of solid particles in waste into account. The porosity and relative permeability of waste change during loading process. A typical example is simulated using OpenGeoSys software to study the influence of age, bulk modulus, permeability on consolidation of municipal solid waste. The model is instructive.
