Weltec Biopower commissions and hands over dairy RNG plant in Wisconsin

In Wisconsin, in February 2025, the German biogas specialist WELTEC BIOPOWER has successfully completed the commissioning and handover of a dairy RNG (Renewable Natural Gas / biomethane) plant in Barron County, Wisconsin. After just four months of construction, the dairy farm produces 2.36 million standard cubic meters of RNG/biomethane annually (86,600 MMBTU per year). This RNG, above gas grid specifications, is processed using advanced membrane-based gas upgrading technology to deliver 272 standard cubic meters per hour (159 SCFM), which is compressed, bottled and transported to a gas grid injection point. This strongly carbon-negative RNG is drawn off the gas grid elsewhere, significantly enhancing the sustainability of the transportation fleets of the buyers.
