myclimate™ Offset Projects China | India | Indonesia | Madagascar | South Africa | United States We have two projects in operation in South Africa: Electricity from sewage gas myclimate™ Electricity from sewage gas in South Africa Project name: Clean Electricity in South Africa The wastewater treatment plant near Johannesburg is important for the local population. Due to fermentation during the cleaning process greenhouse gases (sewage gas) are released to the atmosphere. STI’s implementation partners at myclimate plan to capture the sewage gas and produce clean electricity out of it. The wastewater treatment plant in Sebokeng Township, approximately 30 km Southwest of Johannesburg, purifies 65 million liters of sewage water every day. This process releases sewage gas with a high concentration of methane, a potent greenhouse gas and valuable fuel. STI’s implementation partners at myclimate seek to capture the sewage gas and use it as a fuel for power generation. The infrastructure for capturing the gas as well as the generators for power production were once available at the site, but they haven't been operating for more than ten years due to the lack of spare parts and investment capital. Our project comprises the repair of these generators, as well as the financial resources for the maintenance of the system. Three local engineers are trained for this purpose. The project design aims also at recovering waste heat from the generator sets in order to achieve a better energy efficiency during the sewage treatment. The project triggers new investments in Township Sebokeng, an economically disadvantaged region. Further, it helps increasing the quality of the sewage water purification process, which is crucial to the health of the people that live there. In addition, training and work places for local engineers are created. Project name: Letaba Biomass to Energy Project The The aim of this project is the conversion from coal to biomass for steam generation on a citrus farm. By means of this project, a major employer in the North of South Africa is conversed into an ecologically and economically sustainable business. Health hazards due to coal particles will be reduced. The citrus farm currently consumes 10,700 tons of coal per year to generate steam for the production of fruit juice. The accumulated fruit peelings are dried and used as animal feed, which involves more coal to fire the drying plants. At present the coal is transported to the site from 380 km away. The plant is surrounded by huge forests and sawmills. This means that a large amount of sawdust and waste wood accumulates in a radius of 20 km. The project involves replacing the present boiler with a biomass boiler, which is produced by the Indian company Thermax. The sawdust and waste wood of the region are used to heat the boiler, with the capacity to incinerate around 18,000 tons of biomass per year. The project reduces health hazards and pollution by reducing coal particles. As the sawdust no longer rots in landfill sites, methane emissions are prevented and air quality is improved. The use of waste wood creates jobs for the local population as they are employed to collect the waste wood in the nearby forests. Transporting the wood is also leading to the creation of jobs with long-term employment prospects. Other jobs are created during the four-month construction and sanitation of the system. |
