Bio-drying, as the name implies, is a drying technique that relies on biological activities of microorganisms, bacteria, and fungi, to reduce the moisture content of wet biomaterial waste. (Sadaka et al., 2011 pp.1-4) The drying effect is achieved because of the microbial activity as well as decomposed using oxygen. As the microorganisms feed on the nutrients, C, N and other elements available in the waste, heat is produced as part of the metabolic activities. This heat, assisted by air, is used to evaporate the excess moisture.
