Landfill gas is generated by decomposing organic matter in refuse tips. It mostly consists of methane, carbon dioxide and organic compounds. The substantial methane content of landfill gas enables it to be used as a power generation fuel.

The commercial use of landfill gas as a fuel requires gas to be extracted at a reasonably-consistent flow and quality. Energy Developments has achieved this by drilling a pattern of vertical gas extraction wells linked by underground pipes to a gas collection facility. The entire system is maintained under a vacuum, inducing landfill gas to flow into the collection facility, where gas processing reduces moisture and filters out fine particles. The processed landfill gas is then used as a fuel in either gas engine or gas turbine generators. The power generation facilities are interconnected with a power grid to enable the sale of electricity produced.

Energy Developments has many landfill gas power stations in operation and under development in Australia, the United Kingdom, Europe and North America. With its existing generating capacity and its well-developed technology, we are a world leader in landfill gas power generation.
