Reuse

Over the past years we have built up hands-on experience in applying reused materials across our projects, directly reducing our consumption of primary raw materials.

Integration of circular economy principles in key services

Given the diversified nature of the Group, circular economy principles are integrated where they have the greatest impact.

Revenue from renovation projects has been growing in recent years, driven by large-scale office transformation projects, particularly in Brussels. In 2025 the revenue realised by these types of projects reach 14,8% of our total revenue.

In these projects, the existing building structure is typically retained, with a strong emphasis on the reuse of materials, thereby reducing demand for virgin resources and minimizing construction waste.

Over the past seven years, through large-scale renovation projects where reuse went far beyond small test cases, we have built up real expertise in how to work with reclaimed materials at project scale.

That includes a network of specialist suppliers, material banks, and experts who advise us on availability, quality, and application. Knowledge that now sits at the heart of how we approach renovations.

We are expanding reuse beyond C-construct’s construction projects into our own production companies, with C-metal running the first pilots using reclaimed steel products in their projects.

1000 m² plasterboards get a second life in project UBQ

For our client UBQ, Cordeel Nederland is converting an existing hall into a new factory in Bergen op Zoom. UBQ has developed a process to convert previously non-recyclable household waste into a bio-based thermoplastic composite as a replacement for fossil-based plastics and needed to expand their production.

We proactively analysed which materials could be reused in the project. In collaboration with our subcontractor Van de Wiel Complete Afbouw and the producer Knauf we chose for plasterboards.

Our impact was significant: we reused approximately 1,000 m² of plasterboards originating from renovations and cut to shape for a second life.

Multi – a showcase project to reuse materials

We are proud to have contributed to the redevelopment of Multi, a landmark located in the heart of Brussels. Our construction team strived for a BREEAM Excellent certification for the renovation project completed in 2022, with a strong focus on utilising recovered materials.

To achieve this, we repurposed the original Belgian blue stone and the terrace was laid with 400 recovered granite tiles. Moreover, we incorporated 1,300 metres of aluminium profiles from the Brouckère tower into the balustrades and light fittings of the renovated tower.

Imtech was responsible for the technical installations, and we also reused sanitary equipment. C-wood built the entry hall desk from reclaimed material.

We were inspired by our customers Whitewood & Immobel’s ambitious vision for this project, which pushed us to prioritise the use of reclaimed materials and circular construction.
