These unique projects included the first digester system in the United States to generate both electricity and pipeline grade natural gas. The Fennville system processes manure from 2,200 cows and converts the methane into power.

For the Freeport site, the Newkirk-Theka team designed, managed, built and supported relocation of 1600KW natural gas cogeneration facility for use on digester site. The system provides full heat recovery for digester tank heating and waste water evaporation.
