Therefore, the manufacturing process of RDF is required improvement and transform of MSW by reducing the moisture content, which this waste will become the hight quality fuel. The Biodrying is a drying technique by using microbial degradation process consist of bacteria, and fungi, which are reducing the moisture content of biodegradable garbage or MSW (Sadaka et al., 2011).
