Abstract

Gas generation within solid waste landfills occurs as a result of biodegradation of organic matter in the landifll.Biodegradation processes in a landifll are exothermic and highly dependant on microbial growth in that environment.The heat generated during exothermic reaction's increases landfill temperatures.Temperature is an important factor controlling their own internal temperature.Therefore predicting and controlling the temperature variation within a landfill are essential to ensure normal gas generation an drecovery and enhance stabilization processes.This paper presents a mathematical model to estimated the temperature distribution resulting from the heat release during organic waste decomposition in layered solid waste landfills.The heat source within the landfill is estimated based on the amount of heat generated during the biodegradation processes.Temperature profiles are obtained by solving the heat flow equation within the landfill.The resulting model is coupled with a gas generation and transport component ans. was used to simulated data from a field scale test.
