Wet fermentation of wastes and agricultural residues for the production of heat and electricity

An essential part of commercial and industrial wastes is composed of organic substances. Utilization of these wastes to generate heat and electricity is the goal of fermentation plants. The process behind this biological transformation occurs through the activity of anaerobic microorganisms in the absence of air or oxygen. In wet digestion plants for waste, mainly structurally-poor feedstocks such as commercial kitchen and food wastes, fats, oils and greases (FOG), distillery wastes or wastes from industries such as animal feed or food and beverage production are fermented with agricultural wastes such as crop residues, solid and liquid manure.

Wet digestion of agricultural residues

For wet fermentation, silage of various crops is usually used as feedstock. When solely energy crops are processed, a multi-stage system with combined high solids and wet digestion is required to optimally exploit the feedstock. A substance similar to liquid manure is produced as a by-product of wet fermentation, which is chemically much less aggressive than pure liquid manure as fertilizer. In addition, nitrogen availability is improved and the odor is less intense.
