Greece's first biogas plant inaugurated october in Kavala

Greece's first biogas plant was inaugurated in Kavala on Saturday night by Drama-Kavala-Xanthi supra-prefect Costas Tatsis and Kavala prefect Theodoros Kalliontzis.

The new, ultra-modern plant will produce biogas and organic fertilizer through a state-of-the-art integrated animal waste management system.

The 3.5 million euros model unit, unique in Greece, was built by the listed company KREKA S.A., based in Kavala, and was co-financed under developmental law 3299/2004 by the company's own-capital (50 percent) and the economy and finance ministry (50 percent).

The animal waste management system comprises a furnace where dead animals and material hazardous to the public health, such as bones, blood, entrails are incinerated, and an anaerobic digestor -- an aneorobic digestion processing and biogas production unit in which manure, expired milk and other foodstuff unfit for consumption will be destroyed.

A treatment process of the above waste produces biogas, namely methane, which is used as fuel for the needs of the venture, such as heating or for combining of the organic waste in the bio-reactor, as well as for the production of steam and heat for the sterilization of solid waste and the operation of the incinerator. The biogas left over from the above activities is stored in a special container and is used for the production of electricity.

Anaerobic digestion is a series of processes in which microorganisms break down biodegradable material in the absence of oxygen. It is widely used to treat wastewater sludges and organic wastes because it provides volume and mass reduction of the input material. As part of an integrated waste management system, anaerobic digestion reduces the emission of landfill gas into the atmosphere. Anaerobic digestion is a renewable energy source because the process produces a methane and carbon dioxide rich biogas suitable for energy production helping replace fossil fuels. Also, the nutrient-rich solids left after digestion can be used as fertiliser.
