Greece: Engineering Weltec Biopower to Construct Biogas Facility in Greece

Editor: Ahlam Rais

Weltec Biopower will be building a new 500-kW biogas plant in partnership with Tetoros Machinery for a Greek Abattoir. The Veria facility will make use of the animal waste to generate efficient bioenergy.

Vechta/Germany – In the summer of 2020, Weltec Biopower will start building a biogas plant in Veria, northern Greece. The main investor and operator of the project is one of the largest abattoirs for cattle and pigs in Greece. The 500-kW plant – which Weltec has planned in collaboration with its Greek partner Tetoros Machinery in Megara – is set to go live as early as mid-November 2020.

For many years, a lot of animal waste has accumulated in the north of Greece. According to the Greek research institute CRES, the waste from animal husbandry and slaughtering throughout Greece amounts to 17.5 million t/year. This corresponds to a potential biogas capacity of approximately 370 MW. The capacity currently installed in Greece is only about 83 MW.

The new Weltec plant in Veria will make use of part of these resources for the generation of energy. The anaerobic digestion process will mainly use cattle manure and meat processing leftovers. Apart from these substrates, the 4,903-m3 stainless-steel digester will also be fed with production wastewater and fats. The input substances will come from the operator's own abattoir and farms as well as from farmers in the vicinity.

Specialist Book „Heat Transfer Technique“The comprehensive standard work „Heat Transfer Technique“ offers not only a detailed and well-founded presentation of the basics of heat transfer technique, but also shows the latest state of the art and the latest regulations in the use of organic fluids. Thematically, the book is rounded off with an overview of property data of organic heat transfer fluids as well as many use cases from practical experience.

The highly efficient digestion will start with a customised input process. For this purpose, the substrates will first be loaded into a 60-m3 moving floor feeder. The feeder will transport solid substrates, such as orange peels, to the Multimix unit, where they will be shredded and then pumped to the digester. Liquid substrates will be pumped directly into the digester from two storage units. "Following the digestion process, the entire digestate will be treated in a downstream hygienisation unit", explains Alain Priser, International Sales Manager at Weltec Biopower.

Meanwhile, Greek investors are looking for such custom-tailored plants in order to make profitable and climate-neutral use of the wide variety of raw materials. This is the only way how the share of renewable energies in the power generation can be doubled from the current level of 30 per cent to 60 per cent in 2030. This target was defined in National Energy and Climate Plan 2021 to 2030 (NECP) adopted by Greece. An intermediate step will be to shut down 14 coal-fired power plants in the next five years. Besides natural gas, renewable energies are to play a key role in closing the resulting power supply gap.

In the coming decade, Greece will invest some 9.7 billion dollars in such plants. During this period, the installed biogas and biomass utilisation capacity is expected to triple. In this process, new laws are to provide investment security. "The Greek power grid operators will be required to preferentially connect these plants to the grid, purchase their electricity and pay defined minimum prices", explains Weltec's Greek partner John Tetoros. Tetoros Machinery and Weltec Biopower have collaborated in the Greek energy reform since 2007. With a portfolio of 18 plants and extensions that they have set up, they are the market leader for biogas plants in Greece. Based on the concept of the latest plant in Veria, more plants are likely to be added to the portfolio.
