Clay extraction in the Gartroper Busch has a long tradition. Adjacent in the south of Hünxer Straße the roof tile manufacturer Nelskamp is located, the company, however, no longer processes locally extracted clay.
In the early 1980s the company Nottenkämper started backfilling the area in the Gartroper Busch that is called today the old ash deposit area. Subsequently the so-called windthrow area was extracted, backfilled and completely reforested with high-quality plant stock until the end of 2011.
The hazardous waste landfill of the company Abfallentsorgungsgesellschaft Ruhrgebiet mbH (AGR) is situated in the south of the Nottenkämper company premises.
