WELTEC BIOPOWER building biomethane plant for Ireland

In Ireland, WELTEC BIOPOWER is currently building a biomethane plant for the Irish company Evergreen Agricultural Enterprises Limited. The plant at the company’s headquarters in Monasterevin, County Kildare, will go into operation in mid-2026 after a total construction period of 11 months.

The €50 million project comprises four digesters and one stainless-steel secondary digester, each with a volume of 4,900 cubic metres. These are mainly used to ferment production residues and by-products from the Irish beer and whiskey industry. The materials are readily available and do not compete with feed production, as they are unsuitable for animal feed. Three additional tanks are used to store liquid substrates. “Despite its size, the plant, with an annual processing capacity of 165,000 metric tons, will be built in just six months of pure construction time. Construction is proceeding according to plan and mechanical completion is scheduled for the end of this year,” says Tobias Gerweler, Managing Director of WELTEC BIOPOWER. “The decision not to use grass silage was a conscious one, so that we would not be competing with the livestock industry,” Patrick Meade continues. A combined heat and power plant (CHP) installed on site generates around 1 megawatt of power for the operation of the plant and supplies heat for the digesters.
