GERMANY - The German city of Lunen is set to begin 2010 with all its heat and power generated from biogas. The gas will be produced from the town's organic waste, including cow dung and horse manure from local farms, corn, wheat and grass.
The waste will undergo anaerobic digestion in two digesters sited in the city's industrial park, reports UtilityWeek. The resulting biogas will be plped across the city to generating plants which will produce heat and power for the city's 90,000 inhabitants. The gas will be used to generate 6.8MW of power using Schmidt cogeneration units.
The new underground pipes required to transport the gas are being laid by tunnelling robots so the work can be completed without disturbing residents.
"What makes this project exciting is the combination of cogeneration with renewable energy in an urban environment," said Peter Kindt, the chairman of local heat and power provider Alfagy.
