The construction and demolition sector is responsible for about a third of all waste generated in the European Union. Our big goals are to
- prevent anything from becoming waste as much as possible by increasing our focus on mapping what’s inside our building (material passports) and using circular building practices (e.g. design for disassembly)
- Reduce the amount of waste throughout the entire Group
The industrialisation of the construction process is key to reduce waste: By prefabricating concrete structures in a weather-proof, industrial environment, we can decrease potential mistakes on-site and avoid waste being created in the first place.
Additionally, we will focus on splitting waste streams better and trying to find suitable applications for those waste streams. We acknowledge that what might be waste for us, might still be a valuable resource for others. By setting up partnerships across our value chain we will try to valorize our waste streams, keeping them in the loop as materials and therefore accelerating the circular economy.
Our top-5 waste streams account for 91% of the total amount of waste and are therefore the most material waste streams.

C-concrete in Temse
- Is used for surplus concrete and splits cement, sand, grind & water
- This results in a decrease of concrete waste
- The water is thoroughly cleaned and released back into the dry dock
- Starting from 2023, we will reuse the recuperated sand & grind in our operations
- The remaining surplus of concrete is used to produce jerseys
- This approach was started at the end of 2022
- We were able to reduce our concrete waste with 7.5 ton
- Steel waste from production is given to the supplier of connection bolts.
- They are producing new bolts from it which we use for the transportation of our prefab elements.
- Additional steel waste represents only 3-4% of the total
- Formwork wood waste:
- Reuse as long as possible
- Recycling of unusable pieces and pieces that are too small
C-supply: Collaboration with material banks
- Overstocks are given to material banks or thrift shops (“Kringloopwinkel”) so that the materials get a second life.
- Materials that return from construction sites of Cordeel zetel Temse and are not reused on other construction sites in a period of 6 months are also given to material banks
Avoiding food waste
- A surplus of catering from meetings is distributed among employees of the respective building and/or stored in fridges which leads to happy colleagues.
- On the safety day in Temse in August there was a large surplus of pastry which was delivered to a local food bank.
