Biodrying is a process of drying organic matter with the help of microorganisms. It is a sustainable and cost-effective method of waste management that utilizes bacterial degradation and heat generation to reduce the moisture content of organic waste, such as sludge, agricultural waste, and organic industrial waste. This process can reduce waste volume by up to 70%, as well as reduce odors, pathogens, and other pollutants. The dried product can then be used as fertilizer or converted into biogas and biofuels.
