The Greek agricultural sector has trusted WELTEC BIOPOWER’s biogas technologies since 2007 – and this trend is continuing. Most recently, three biogas plants were built, which the German manufacturer designed together with Tetoros Machinery. Two of these are located in the Epirus region, in northwestern Greece: a 1-megawatt plant in the town of Arta and a 500-kilowatt plant in Ioannina. The third one, a 250-kilowatt biogas plant project, was realized in Serres, in central Macedonia. An upgrade of the CHP plant to 750 kilowatts is also being implemented. The plant in Ioannina will go into production in the fall of 2023.
At all three sites, the materials are first sent to a pre-storage tank. Special agitators and pump technology ensure the pretreatment. In the digesters, the proven agitators then mix the substrates for efficient biogas production. The two digesters in Arta each hold 4436 cbm, in Ioannina there is a 3993-cbm digester, and the tank in Serres measures 4905 cbm. “All tanks are made of high-grade stainless steel,” specifies WELTEC BIOPOWER.
