Limited landfill space and the high levels of greenhouse gas and methane emissions generated by waste have both been important issues for the municipal government of Johannesburg, South Africa.

As a response to these issues, the municipality has launched a landfill to gas project with the goal of collecting, destroying and converting landfill gas produced at the site into energy for household use. Landfill gas generated by anaerobic decomposition of organic waste in landfills is retrieved and eliminated with a flare, and the captured gas is fed to a modular electricity generation plant. Then, the generator burns the methane in landfill gas to generate electricity, which is then sold to a local power buyer. This method of generating energy from the sites does not pollute the environment; instead, the emissions are used to fuel electricity generators.

Based on the projected waste per day, the total potential electricity capacity of the sites is estimated to be 18,6 MW, allowing around 12,500 households to benefit from the energy generated. The total annual electricity generation for all sites is expected to be 150 GWh.
