Bio-drying reduces 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 Samutprakarn province, was used as a substrate. The influence of MSW height in the reactor on heat generation and evaporation were investigated. High surface area leads to low heat accumulates in MSW. The results were indicated that when the pile volume to surface area ratio (V/A) was equal to or greater than 0.6 and pile height more than 0.6 m, self-heating could be occurring inside the pile. However, the other parameters such as C/N ratio and turning frequency also need to considerate when the rotary bio-drying process is designed.
