Captured Landfill Methane (CLM)

Our Captured Landfill Methane (CLM) Division generates renewable baseload power from over 100 sites through the capture and combustion of methane, a naturally occurring gas from the decomposition of organic matter contained in the waste of landfill sites.

Methane is one of the Earth's most harmful greenhouse gases being 25x more potent than carbon dioxide.

Being able to generate power from CLM significantly reduces the impact of methane emissions on climate change as well as providing an efficient and secure source of local power generation.

We extract CLM in a controlled way by applying a suction through a network of installed pipelines and gas wells on the landfill site. Modular gas reciprocating engines then use the CLM as a fuel source, converting it into electricity.  

Each year, we capture over 300,000 tonnes of methane and generate approximately c.1 TWh of electricity from our CLM operations.
