Abstract: Bio-drying is the process to reduce moisture from Municipal Solid Waste (MSW) by using the heat from aerobic bio-degradation. This study aimed to investigate the effects of pile height on heat generated in rotary bio-drying process reactor for drying high initial moisture content MSW, allowing satisfied energy content biofuel. The MSW from the Administrative Organization of Tumbon Kaerai, kratumban samutsakorn province were used as a substrate. The influence of MSW height in the reactor on heat generation and the evaporation was investigated. High surface area lead to low heat accumulates in MSW. The results were indicated that when the pile volume to surface area ratio (V/A) was equal or greater than 0.6 and pile height more than 0.6 m, selfheating could be occurs inside the pile. However, the other parameters such as C/N ratio and turning frequency also need to considerate when rotary bio-drying process are designed.
