Joburg - Landfill Gas to Energy

Date Published: May 22, 2017, 3:43 p.m.


ohannesburg, a city of 3.8 million people, has to handle more than 1.6 million tons of waste annually and to oversee eight landfill sites, which harm the environment and the surrounding communities. In addition, the City is facing serious difficulties regarding energy provision and particularly load-shedding issues. In this context, the City launched a landfill gas-to-energy project in 2007. The project uses gas turbines to drill out methane gas, caused by the degradation of bioorganic compounds at its landfill sites, and to generate renewable energy for the municipal grid, thus offsetting largely coal derived electricity. The project, which should be fully operational by the end of 2015, was developed through a Public-Private Partnership (PPP) with the British company EnerG Systems under a 20 years contract. To benefit from additional revenue, the City initiated a Clean Development Mechanism (CDM), which was completed in November 2012, and signed a Power Purchase Agreement (PPA) with the national electricity company, Eskom, to sell the energy produced in the landfill sites. Since 2011, wells to extract and flare the greenhouse gases as well as energy generators have been built in the five landfill sites selected for the project. Energy commercialization started at the beginning of 2015. The expectation is to produce 19MW per year starting in 2016 from the five landfill sites, which should be enough to provide energy to 12,500 households. By the beginning of 2014, the project had managed to reduce pollution and noise for surrounding communities, had produced 137,888 Certified Emission Reductions (CER’s) and destructed 18,288,457 Nm3 of landfill gas.
