Burwood Landfill (trigeneration from landfill gas)

Trigeneration refers to the conversion of one energy input (in this case, landfill gas) into three energy outputs; electricity, heat and cooling. The heat recovered from the gas engine's jacket water and exhaust gas streams is to be used for both heating
Description of facility: 

The gas engine selected is a Waukesha model VGF36GLD, with an electrical output of 475kWe and a thermal output of 712kW.

Entec was been engaged to design, supply, install and commission the trigeneration plant for the Council's new Civic Centre building in the Christchurch CBD.

Fuel gas for the project is being piped from the Burwood Land-fill, on the north-eastern outskirts of the city. The gas pipeline travels via the QE2 Sports Complex, where Entec installed a smaller cogeneration plant in 2007, and via the Bromley Waste Water Treatment Plant which is home to a 1.5MW Waukesha cogeneration plant.
