The Mare Chicose landfill project collects and flares landfill gas and generates electricity. This is the only landfill site on Mauritius Island, an island threatened by rising seas due to climate change and located off the east coast of Madagascar in the Indian Ocean. It is a large-scale, active landfill that has been operational since 1997 and has approximately 7.9 million tonnes of waste in place as of November 2018. It receives 530,000 tonnes of waste per year.
The project activity involves the installation of an active landfill gas collection system, an enclosed flare system, and a modular electricity generation system. Vertical wells spaced 40M apart are drilled into the landfill to enable maximum extraction of the gas.
Carbon revenues are used to create a more efficient gas collection system than required by law, including wells, piping, and intermediary gas collection stations. Funds from carbon are also used to create an electrical plant in order to generate electricity from landfill gas. This landfill actually flares more of the collected gas than required by law but only flares when the electrical plant is not operating. (Flaring is the situation when methane gas is burned to break the gas down into its components CO2 and water, which are much less harmful to the planet than methane has a global warming effect 25 times higher than CO2).
