Hitachi Zosen Inova USA said May 10 it had been awarded a contract to build sustainable waste-to-energy and renewable natural gas (RNG) infrastructure for 3 Rivers Energy Partners, which is developing, with Canada’s TC Energy, RNG capacity at the Jack Daniels Distillery in Knoxville, Tennessee.

The integrated system consists of a 648,000 gallons/day wet anaerobic digester (AD), amine biogas upgrading capacity and integrated process piping and controls. The distillery will provide spent stillage as feedstock, and will receive biogas from the AD to provide 65% of its gas needs.

Once in operation, the facility will produce 2,700 ft3/minute to power the distillery and fertiliser that will be used in local agriculture operations. Construction is expected to begin late next year.
