Short Summary
From a disused strip mine, which has functioned since 1976 as a waste dump where 15 Mio. tons of waste have been collected, the waste dump gas is to be utilized; waste gas is sucked out, compressed and used by gas engines for the production of power and, to a small degree, heat.
The dump collects an annual amount of 600,000 tons.The annual power generation is approximately 8,5 Mio. kWh. The electricity is fed into the local network. Waste gas which has too low a methane content is directed into a flare system and burned at 1,200°C.
