EnviTec Biogas Commissions its Largest U.S. Anaerobic Digestion Plant Online

EnviTec Biogas has achieved a major milestone in the U.S. with the launch of its largest anaerobic digestion plant in the country. Operated by its U.S. subsidiary, the facility strengthens EnviTec’s collaboration with SJI Renewable Energy Ventures and regional partners. Located in South Dakota, the plant has been processing over 300,000 gallons (1,100 cubic meters) of manure daily from more than 9,500 dairy cows since early this year. It is expected to generate 483 standard cubic feet per minute (scfm) of renewable natural gas (778 Nm³/h of biomethane), equivalent to approximately 177,000 million BTU annually. This milestone highlights EnviTec Biogas’s continued leadership in the U.S. biogas sector, which began with its first project in 2012.

“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,” explains Lars von Lehmden, CEO of EnviTec Biogas USA Inc. Eight of these 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,” adds Timothy Logan, President of EnviTec Biogas Construction LLC. “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 U.S. 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.

“Our concrete tank design is the first of their kind to be approved in South Dakota,” Logan adds. In addition to constructing the integrated biogas and biomethane upgrading facility, the client has also signed a multi-year service contract with EnviTec to provide technical scheduled services, service on demand, 24/7 hotline support, and biological services from the office/warehouse in Watertown, SD. “Especially during the commissioning and ramp-up phase, we have been providing weekly sampling and analysis through our laboratory in Watertown,” says Logan.
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. Three 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.
