MuP Umwelttechnik GmbH
MuP Umwelttechnik GmbH is a Private limited company (Ltd.) registered in Germany under HRB 332893 Mannheim, and its current status with Handelsregister (Commercial Register) is active. The company was incorporated on 19 April 1985 and lists its registered address as Heidelberg, Germany. 1 shareholder is on record for MuP Umwelttechnik 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 28 October 2026.
