Sustainability requires foresight and an integrated approach to the development and implementation of forward-looking energy and environmental projects. The energy supply serves the core business of production and must therefore be integrated into the strategic development of the company in the best possible way. The Gammel Engineering team worked with BMW and ArGe Siemens AG / Ulrich Müller GmbH to develop a customized plant model. The key element is the use of waste heat from the exhaust gases of the new aluminum smelting plant to generate hot water all year round. Furthermore, the electricity base load is now generated via the new additional combined heat and power plant (2,681 kW electrical output, 2,366 kW thermal output) with heat-side integration into the hot water network. The heat is primarily fed into the two absorption chillers (1,050 and 1,100 kW cooling capacity) to supply the plant's cold water network. What is not required for cooling is fed into the plant's hot water network. A separate building was constructed for the new energy systems.
The CHP units generated electricity in good time before 01.08.2014 and are therefore exempt from the EEG levy.
The Gammel Engineering team would like to thank both BMW AG and ArGE Siemens AG / Ulrich Müller GmbH for the trust they have placed in us.

Our employees voted together and decided to support the Hölzgen family with a donation from the Gammel Family Social Fund.
The exchange on digitalization, AI and new technologies is becoming increasingly important for companies. We are therefore all the more pleased that our authorized signatory Thomas Winkler will also be supporting these topics in the digitalization committee of the Regensburg Chamber of Industry and Commerce in future.
On 12.05.2026, Gammel Engineering was once again a guest at the Waltl-Hof for the annual asparagus dinner. In a relaxed atmosphere, with excellent food and good conversation, the focus was on one thing above all: spending time together as a team.
