New section

It has been working intensively in the northern Ruhr area for years - at the end of the year the Emscher conversion should be largely completed.The new drying system that will start on Friday is now one of the last big steps on the way there.

Effects like a greenhouse

The system is impressive and futuristic at the same time: 32 huge halls that look like greenhouses, make it out.There are large pools with the damp, stinking sewage sludge.

The drying of the sewage sludge works through the heat heat that penetrates through the glazed building.The effect is similar to a greenhouse.

Emschergenossenschaft: important climate project

Robots automatically take on work in the system

The whole thing is pure high -tech - everything runs fully in the halls.So far, the moist mud had to be fed to the damp mud so that it burns better.Around 70.000 Tonnen CO2 können jetzt jedes Jahr eingespart werden, sagt die Emschergenossenschaft.

This also emphasizes that the sustainable handling of sewage sludge is extremely important for the climate -friendly energy generation. Die Anlage in der Nähe der B224 ist rund 40.000 square meters tall.
