Abandoned and decaying factory

Looks like the administrative buildings are occupied. Just to the right (east?) and across the rail tracks you will see a hazardous waste clean-up project. It looks like a field, but is more likely a "coffin" where the toxic waste from the factory has been entombed in an earthen monument. Around the site there are probably test wells for sampling the ground water. You see this a lot a former solid waste dumps and refineries and smelters.

Yes, it was the Coking Plant Hansa. The former hard-coal mine Hansa is 400 meter south of it.
