Once the final units begin operation, the 35-MW project will produce enough renewable energy to support the monthly requirements of approximately 100,000 average households in Istanbul, making it one of the largest waste-to-energy projects in the world. With a total waste disposal volume of 47 million tonnes and a daily disposal rate of about 14,000 tonnes, the two landfills in Istanbul are among the largest in the world. Methane-rich landfill gas is created as organic solid waste gradually breaks down. To prevent uncontrolled venting of the gas, it is extracted via a network of pipes, processed and fed into GE's Jenbacher engines to generate a renewable supply of electricity.

One of the world`s largest landfill gas-to-energy projects unveiled in Istanbul
One of the world's largest landfill gas-to-energy projects was formally unveiled in Istanbul, Turkey, on 25 April. The landfill gas project, owned by Ortadogu Enerji Sanayi Ve Ticaret, was developed as part of a national initiative to reduce the environmental impacts of solid waste facilities and use the landfills' gas to generate electricity. Turkey has been modernising its energy infrastructure to encourage the development of new, domestic alternative and renewable energy supplies, including landfill gas. The renewable energy plants will be located at two landfill sites in Istanbul, Odayeri and Komurcuoda powered by a total of 23 GE Jenbacher landfill gas engines. The first nine units have been commissioned and the final systems are scheduled to be delivered in 2010.
