About the Solution:
Sevana's current projects include the joint ownership and operation of the New Energy One dairy manure digester facility near Twin Falls, ID. This facility has six CSTR digesters which processes the manure from a dairy herd which totals approximately 18,000 cows and generates renewable power for EV charging. Upon the completion in Q1, 2022 of an expansion, the facility will produce renewable natural gas for supplying CNG fueled vehicles in LCFS markets.
The Sevana team was also instrumental in the expansion of an a CSTR digester facility in the Pacific Northwest which is now one of the larger CSTR based RNG plants in the world. The company is also active with the development of multiple dairy and swine RNG projects in several agricultural regions across the midwest US.
Sevana’s facilities create job opportunities and steady markets for existing agricultural operators and businesses. Consistency in markets and in product availability helps communities to withstand volatile commodity markets and uncertain growing conditions.
