Biogas

Anaerobic Digestion is a series of processes in which micro-organisms break down biodegradable material in the absence of oxygen.

1. Anaerobic digestion is a renewable energy source because the process produces mainly methane and carbon dioxide:  biogas suitable for energy production helping replace fossil fuels.
2. Also, the nutrient-rich solids left after digestion (digestate) can be used as fertiliser after a deep stabilization.
3. It is widely used to treat wastewater sludges and food organic waste derived as by product from agro industry process, due it provides volume and mass reduction of the input material.

Systems utilise the anaerobic digestion process to transform organic raw material to produce biogas and organic fertilizer once they are duty stabilized.

• Raw materials are derived both from agriculture product or agro-industry process by-products and from urban waste or water cleaning systems by products.
