Heidelberg Materials acquire SER Group

SER Group

Circular economy expansion with acquisition of leading recycling company in Southern Germany

HEIDELBERG Materials have acquired SER Group, a leading integrated company in the demolition and construction materials recycling sector, based in Heilbronn, Southern Germany.

With an annual revenue of around €50 million and three modern recycling sites, SER Group are the market leaders in the greater Heilbronn area and employ more than 220 people.


The acquisition comes shortly after the take-over of Berlin-based RWG Holding GmbH in November 2022 and highlights Heidelberg Materials’ focus on enhancing its circular economy activities.

‘Through the acquisition of SER Group, we are further expanding our circular materials offering in Germany. The reuse of building materials and concrete recycling are crucial to achieve our ambitious climate targets. We aim to offer circular alternatives for half of our concrete products worldwide by 2030,’ said Dr Dominik von Achten, chairman of the managing board.

In future, Heidelberg Materials plan to prioritize the use of recycled materials in concrete production over the use of primary raw materials. ‘This not only conserves natural raw material resources, but also enables us to open up new business areas and broaden our offering with optimized recycling products in Germany,’ said Christian Knell, general manager Germany.

‘With their focus on sustainability and circular economy, Heidelberg Materials are the ideal strategic partner for us to further successfully lead our company into the future,’ affirmed SER Group’s main shareholders, Herbert Röger and Michael Wiener.

Heidelberg Materials say they are working intensively on innovative methods for processing, reprocessing, and returning high-quality recycled materials, such as demolished concrete, to the construction cycle, and that SER Group’s business will ideally complement their existing portfolio.

The acquisition, which is subject to approval of the antitrust authorities, is expected to be completed in the first half of 2023. Both parties have agreed not to disclose the purchase price.
