Buchen UmweltService GmbH
Buchen UmweltService GmbH is a Private limited company (Ltd.) registered in Germany under HRB 2733 Köln, and its current status with Handelsregister (Commercial Register) is active. Its registered address on file is Köln, Germany. 1 shareholder is on record for Buchen UmweltService GmbH, and since every one of them is a company rather than an individual, this particular filing does not on its own establish an ultimate beneficial owner (UBO) — identifying one would mean tracing the ownership of each shareholding company in turn. This profile is sourced directly from Handelsregister (Commercial Register) and was last updated on 25 September 2026.

Directors and officers of Buchen UmweltService GmbH
The Geschäftsführer (managing director) of Buchen UmweltService GmbH currently on record is Steffen Brillat; 18 of the 48 officer records shown for Buchen UmweltService GmbH are current appointments, filed with Handelsregister (Commercial Register). The remaining 27 records shown (Hermann Lewandowsky, Klaus Scherler and 24 others) are former appointments that have since been resigned.

The source filing doesn't specify representation authority — whether officers can act individually or must sign jointly to bind the company — so that detail isn't available here.

Data availability
Those 12 subsidiaries span Germany, Poland, Bahrain, Estonia, Norway jurisdictions, though this list should not be read as complete — subsidiaries only become visible here where shareholder data has actually been filed with a register, so holdings in jurisdictions without that filing simply won't appear. Four of the 12 go a level deeper still, with their own further subsidiaries recorded beneath them — additional ownership layers this view doesn't expand.
