The main purpose is the sale of the plant to the distributor of electricity from generators powered by biogas derived from biomass. This case involves the use of anaerobic digesters adapted appropriately loaded with waste material derived from animal farms, industrial waste (EWC) and PAE (energy production from agricultural sources). After a period of biological attack, the fermented product that produces biogas, through adequate gas tanks, will be conveyed to the combustion engines used to produce electricity grid. The heat generated by the engines (water circuit and / or smoke circuit) will be recovered for the heating of the fermentation tanks.
The fermented material is then stored in a tank and then separated from the final liquid, respectively, resulting in excess compost and liquid fertilizer. The system generally is also ready to supply heat to the outside form of heating..
In some systems properly configured and built, you can also enter the MSW (organic waste).
In practice, using separators, you get an organic component that is placed together with other sludges in the plant and a part composed of inorganic material (plastic, etc …) then it will follow a different process of disposing..
