As South Africa grapples with an electricity crisis, our Joburg Waste to Energy offset project strives to keep the lights on whilst cleaning up the municipal sites around Johannesburg.
Municipal landfill sites are not only an eyesore, they also pose serious environmental and health hazards by generating huge quantities of methane gas. Methane gas is produced when organic waste – food, garden waste, street sweepings, textiles, wood and paper – is broken down by bacteria that are naturally present in the waste, as well as in the soil that is used to cover the landfill. As a greenhouse gas that is 21 times more harmful to the environment than carbon dioxide, methane can migrate underground and become explosive.
If managed correctly, methane can be captured and destroyed by flaring it. The Joburg Energy to Waste offset project goes a step further by capturing methane from five landfills sites in Johannesburg and turn it into electricity, solving two serious issues that South Africa currently faces.
Five municipal landfill sites around Johannesburg have been developed using the latest technology by energy management company Ener-G Systems. After capturing methane gas, the project converts it into electricity via a network of pipes in the landfill. The gas is pumped in a chimney where it is combusted into harmless emissions. This is the project’s first phase.
The project’s next phase will see the installation of five generators that will channel the gas as fuel for electricity generation. The generators will transfer the energy to the municipal distribution grid.
When completed, the project will produce 19MW of electricity – enough to power 16,500 medium-sized houses. This will make it the biggest landfill waste-to-energy project in South Africa.
This project is registered under the Clean Development Mechanism, allowing companies to credibly offset their carbon footprint to make a sustainable environmental impact. The Joburg Waste to Energy Project is measured and monitored by internal and external researchers and audited by independent auditors as required by the Clean Development Mechanism (CDM) guidelines.
The project contributes towards solving South Africa’s electricity crisis by eventually providing power for up to 16,000 homes
Five major landfill sites around Joburg are covered making them cleaner, safer and reducing the risk of methane explosions
Increase in employment opportunities as local contractors and labourers were required for construction, as well as long-term staff contracted to operate and maintain the system.

The Certified Emission Reductions (CERs) generated by the Joburg Waste to Energy Project are eligible for use under the South African carbon tax, providing companies the opportunity to reduce their carbon tax bill.

Who hasn't been captivated by the recent US election results? With Biden the projected the winner, the planet could breathe a big sigh of relief with his commitment to rejoin the Paris Climate Agreement and reach net-zero carbon emissions by 2050. https://bit.ly/3piCizW
