On the site of the rolling mill in Ilsenburg, a new production facility (finishing shop) with a hall floor area of about 30,000 m² was built on the site of the former gas generator plant (CHC and PAH damage from the operation of the former gas generation plant). For this purpose, the remaining contaminant hotspots in the subsoil were remediated after the demolition of the buildings and facilities, and the soil and foundation remains from the excavation area, which were contaminated to varying degrees, were removed and disposed of (a total of approx. 380,000 t of soil and construction debris).

Total project duration: 2014 - 2020
Total project costs: > €100 million
Area size: approx. 60,000 m²
