September 2026: Around 750 m³ of concrete saved – at the Green Campus in Rüsselsheim

A new, modern location for Opel’s global headquarters and Stellantis’ German headquarters is being developed on the historic Opel production site in Rüsselsheim as part of the Green Campus project.

Our Unidome system was used for the construction of the slabs.

The results speak for themselves:

  • approx. 8,170 m² of voided slab area
  • approx. 750 m³ of concrete saved
  • approx. 155 tonnes of CO₂ saved

By using Unidome void formers in a targeted way, we were able to reduce concrete precisely where it is not structurally required — saving valuable resources as well as a significant amount of CO₂.

It is especially rewarding when the impact of a project can not only be demonstrated in figures, but also experienced directly on site.

For this project, our client, Adolf Lupp GmbH + Co KG, even quite literally left its mark on the voided slab.

A small detail on site that definitely catches the eye.

Many thanks to everyone involved for the excellent collaboration and successful implementation!
