Efficient, sustainable management of organic waste to achieve energy self-sufficiency while introducing circular economy processes into the agri-food industry.
This is a self-supply project based on organic waste from the agri-food industry. The biogas plant was designed, built, commissioned and managed by Genia Bioenergy. The biogas thus produced is used for self-supply and the digested residue for compost and fertilizers which are then reused by the company, thus constituting a perfect example of the circular economy in practice.
This biogas plant makes the entire agri-food chain more efficient: it adds value to the by-products not fit for human consumption and transforms them into material that can be used as ingredients for animal feed, digested biofertilizer or vehicle fuel for trucks.

The treatment of organic waste through anaerobic digestion processes results in two valuable products: biogas and digestates.
The goal of the plant is to achieve zero waste disposal by obtaining value from these waste materials in the form of energy and fertilizers that return to the economic cycle by means of natural organic treatment. The biogas obtained from the plant is used as fuel in their own processes in the food industry while the organic fertilizers (in liquid and compost form) are applied to the fields from which the raw materials are obtained to improve productivity.
Digestates are composed of the solid and liquid matter that remains after the microbiological process. They are rich in organic and mineral components and – with proper control and treatment – are used as biofertilizer.
Furthermore, the plant valorises waste to produce biogas and organic fertilizers by anaerobic biodigestion, processing treatment-plant sludge from the agri-food industry, organic waste from slaughterhouses and vegetable waste.
Pre-treatment of the waste is important to ensure suitable proportions in the substrate with which the digester is fed, precise dosing of the additives to activate the digestate and proper control of the digestion timeframes.
The anaerobic digestion process involves fermentation of organic waste by bacteria in an oxygen-free environment. The resulting gas can be used for industrial processes, electricity generation, for upgrading and injecting into the gas grid or as automotive fuel. In this case, however, it is used directly in certain food-industry processes. In addition to gas, it produces compost and high-quality liquid biofertilizer.
Waste that previously posed a threat to the environment and incurred treatment costs for companies is thus incorporated into the circular economy where it generates sustainable energy and high-quality organic fertilizers.
