Southern Landfill, Wellington
Greenhouse gas from Wellington’s Southern Landfill is being used to generate electricity. The landfill gas collection system captures 4 million cubic meters of odorous and environmentally harmful landfill gas each year, this then drives the generation plant. The 1 MW plant generates up to 8 GWh of electricity per year – enough to power 1000 households. UPG provided on-site butt welding services for the landfill, welding approximately 1km of 280mm pipe.
