The pic shows exactly how I remember it when I visited the place. No garbage trucks approaching the site on Heddernheimer Landstraße, no steam rising into the sky via the colorful chimney. Where 2000 tons of household waste are usually delivered every day, incinerated and the waste heat converted into electricity and district heating so that it is always bright and warm in 30,000 Frankfurt households, everything is currently at a standstill. The largest waste-to-energy plant in Hesse and one of the most modern in Germany is out of operation. The operator sat on a high super easy throne in a glass cabin and controlled the operation with one hand. Impressive.
As I remember, they used fossil fuels to burn the trash and the balance of energy was negative, that is, the amount of energy invested was lower than the electricity achieved. But it was considered "green".
