HOUSTON, TEXAS (Editors at Energy Analytics Institute, 28.Mar.2025) — EnviTec Biogas reached a significant milestone in the US market with the recent commissioning of its largest anaerobic digestion plant in the country to date. This, as the biogas specialist — through its US subsidiary — is strengthening its partnership with SJI Renewable Energy Ventures and local suppliers.
Located in South Dakota, the plant has been processing over 300,000 gallons (1,100 cubic meters per day or m3/d) of manure from more than 9,500 dairy cows per day since the beginning of the year. It is expected to produce 483 standard cubic feet per minute (scfm) of renewable natural gas (RNG) (778 Nm³/h biomethane), equivalent to around 177,000 million BTU per year.
This new facility marks a significant milestone for EnviTec Biogas, which has been pioneering the biogas industry in the US since the commissioning of its first project in 2012, the company announced on 28 Mar. 2025 in an official statement.
“This facility marks the fifth of a total of 15 biogas plants we are developing for our client, a leading company in renewable energy and sustainable solutions,” said EnviTec Biogas USA Inc. CEO Lars von Lehmden.
8 of the plants are on farms operated by a leading diversified agribusiness in the US.
“This new facility is a true win-win for both business and the environment,” said EnviTec Biogas Construction LLC president Timothy Logan. “Not only does it convert organic dairy waste into renewable biogas, but it also helps reduce the overall carbon footprint of dairy farming.”
Local tank manufacturing and comprehensive service offerings
Beyond this milestone, EnviTec Biogas continues to stand out as the only provider in the US market offering high-quality, locally manufactured concrete tanks. This is made possible through a sustainable partnership with Collins Precast LLC, a leading producer of precast concrete components and buildings in the Upper Midwest, said EnviTec Biogas USA Inc., an independent subsidiary of EnviTec Biogas AG, Germany.
With the completion of the fifth project in this partnership with SJI, EnviTec Biogas has now successfully delivered one-third of the planned portfolio for its client. 3 additional projects recently completed cold commissioning and are transitioning to ramp up stage, with EnviTec’s first Minnesota projects being brought online later this year.
EnviTec Biogas AG has completed over 700 biogas plants since 2002 in 18 countries worldwide with feedstocks ranging from dairy manure to food waste. EnviTec Biogas AG’s portfolio of technologies includes anaerobic digestion, gas upgrading, ammonia stripping, bio-LCO2 and bio-LNG.
