PHG, GE Open Waste-to-Energy Unit in Tennessee

Two energy companies have opened their waste-to-energy operation in Covington, Tenn.

The collaboration between Nashville, Tenn.-based PHG Energy (PHGE) and Schenectady, N.Y.-based GE Power & Water (a unit of General Electric Co.) uses gasification of wood chips or other biomass such as sewage sludge from the city to generate gas. That fuel is then combusted in a heating unit that supplies a GE Clean Cycle generator with the thermal source to generate power, according to a news release.

PHGE provides the downdraft gasification system and waste-mixing process.
