Let's talk about the circular economy!

To incorporate the CSR dimension into our projects, there are several solutions. Thus, for some years now, the watchword for all projects led by the Rabot Dutilleul Group has been to maximise the eco-design of buildings. The pillars of our policy are the circular economy and upcycling, which aims to use the available resources for as long as possible, notably by re-using them.


Re-using materials and the principles of the circular economy have become the new challenges in the construction world. Although not new, there is growing interest in these challenges.
The aim is to be able to use construction components taken from a former building and to incorporate them into the development of a new project. This is known as “upcycling”, which refers to the action of recovering materials or products we no longer need in order to recycle them. This enables us to extend the useful life of certain products and to take concrete action in favour of mitigating the environmental impact.
Beyond the environmental aspect, the circular economy concept refers to the adoption of a comprehensive approach. It is economically cost-effective because good quality materials can be obtained within a reasonable budget. This type of project also holds out a societal promise with a greater need for human capital to meet its specifications.


The rehabilitation of the National Social Security Office (ONSS) building in Brussels carried out by the teams of Entreprises Louis de Waele is a fine example of a project featuring the re-use of materials. Thanks to this project, the group’s Belgian affiliate won the “Be Circular” competition in 2017 in the “Circular Projects” category. This competition has been organised for a few years now by Bruxelles Environnement, the public service responsible for the environment and energy in the Brussels-Capital Region.
“Re-use holds out the promise of a better future”

The insulation in the mineral wool partitions that used to define the office spaces in the former ONSS building has been re-used for the roofing of the scheme for the on-site refurbishment of the Logis Floréal de Watermael-Boitsfort building dating from 1968, which, since March 2018, has become the new head office of Entreprises Louis de Waele.
