Over the past 25 years, we have developed and operated landfill gas-to-energy projects in the UK, Spain, Poland, Hungary, Lithuania, Morocco, Mexico and South Africa.  Our team is committed to finding new and innovative solutions to manage gases efficiently to generate energy, reduce CO2 emissions and meet environmental requirements.

Producing ‘green' electricity from harmful greenhouse gas and exotic fuels is at the core of our business.
