Modern management of waste around the world has moved from waste disposal toenergy recovery through WtE. Technologies that can be utilized to recover energyfrom MSW mainly include thermal conversion processes such as incineration,gasification, pyrolysis, biochemical conversion processes and chemical conversion.This study focused on the impact of moisture content on the heating value ofMunicipal solid waste from Kabagarame dumping site in Bushenyi District, Uganda.Specifically, wet solid waste samples were analyzed and the impact of moisturecontent on the heating value was evaluated. This study evaluated the impact ofmoisture content on the heating value of the waste. The result showed that dry mattergives out more energy than wet matter. The Gross energy content of the MSW on wetbasis when compared to the Gross energy content on dry basis is observed to be lower.This is attributed to the fact that the moisture content in the waste lowers the heatingvalue of the waste by absorbing the heat thereby reducing the relative efficiency ofheating when the solid waste is combusted. In, wet season, there should be atemporary roof at the dumping site to shelter the municipal solid waste so as tominimize exposure of the waste to moisture as this significantly lowers the Energycontent of the waste
