New group to become market leader for recycled building materials
AUCTUS acquires majority stake in Blasius Schuster Group – launching Urban Mining Group
The transaction
The Munich-based investment company AUCTUS acquires a majority stake in the Blasius Schuster Group (Frankfurt am Main) and, together with its Managing Director Daniel Imhäuser, establishes the Urban Mining Group – a new, nationwide structure for recycled building materials. Imhäuser maintains a significant reinvestment in the Urban Mining Group. It will hold all shares in Blasius Schuster going forward.
The aim is to create a consistently growing group of companies that is organized efficiently and effectively in Germany’s largest bulk material flow – mineral construction and demolition materials.
AUCTUS explains: “Together with Daniel Imhäuser, we want to create the leading group of companies for recycled building materials in Germany – with clear advantages for customers in terms of availability and quality.”

“With the Blasius Schuster Group, we are gaining a strongly positioned company with experienced management. The market for recycled building materials offers enormous growth potential and opportunities for the entire construction industry. Together with Daniel Imhäuser, we want to develop the group of companies into the German market leader. Here we are relying on our proven buy-and-build strategy.”

AUCTUS strategy
The Urban Mining Group is pursuing the establishment of a strong group of companies in the recycling and recovery sector. Blasius Schuster is the platform and first transaction of the new group.
The concept is based on efficiently organizing recycling and disposal services throughout Germany and integrating central services within the Group – with the aim of keeping raw materials in circulation and reducing disposal costs. Material flows, technology and logistics should benefit from the synergies. The Urban Mining Group also aims to simplify the processing of large quantities of waste and recycling. The medium-term benefits for clients:
- Plannable and safe disposal of large quantities of material
- Reliable availability of recycled building materials
- Consistent quality thanks to standardized processes
- Shorter distances and lower costs
- A central organizational structure for complex construction projects
A decisive lever lies in cooperation: a broad geographical presence, industry expertise and technical know-how create solutions that individual market participants cannot offer in this way. The new group of companies is to be strengthened through targeted acquisitions and partnerships. AUCTUS is one of the market leaders in the implementation of buy-and-build strategies in the DACH region and has already established numerous corporate groups in many sectors.
