EnviTec Biogas commissions its largest US AD plant to date

EnviTec Biogas has recently commissioned its largest anaerobic digestion (AD) site in the US to date.
Through its US subsidiary, the biogas specialist said it 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 metres) per day 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, said the company. It commissioned its first project in the US 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,” said 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,” added 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
EnviTec Biogas added that it is the only provider in the US market to offer 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,” continued Logan.
In addition to constructing the integrated biogas and biomethane upgrading facility, EnviTec's client has also signed a multi-year service contract with the company to provide technical scheduled services, service on demand, 24/7 hotline support, and biological services from the office and 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,” said 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.
