As a construction company, Groep Van Roey purchases a large number of building systems and products every year. Within our commitment to participate in the Green Deal Circular Purchasing (GDCA), we have the ambition to purchase two projects in a circular way.
In this context, together with the Scientific and Technical Centre for the Construction Industry (WTCB), we want to examine how we can make greater use of building materials that have already been used in our purchasing procedures, or which contain a higher proportion of recycled material than the standard products we purchase. That is why we started the ProReMat project. That stands for Procurement of Recycled and Reused construction Materials.
Our research was divided into four concrete research questions: Which alternative, circular building materials are available on the market today? Do the alternatives meet the required quality guarantees? Are the alternatives price competitive with the standard products? And which adjustments to the regulatory framework can promote the reuse of materials and the use of recycled materials?
The research questions were also tested on the basis of three concrete building projects: the new primary school in Niel, De Hoorn in Leuven and Cure in Eindhoven.

The research yielded many new insights which we will be able to share widely internally and externally in the near future, for example in our presentations at conferences on circular construction and urban mining.
Integrating reuse into Groep Van Roey's procurement procedures is not easy. However, it is our ambition to integrate the acquired knowledge to the maximum in our DBFMO tenders to put reuse and recycling at the top of the agenda with the designers and clients. The chance of success varies greatly from case to case.
Furthermore, the BBRI wants to keep the database up-to-date and make it available to Belgian construction companies.
Finally, the insights gained from this project will help the BBRI to develop a technical reference framework for reuse and recycling, which will hopefully alleviate the cold feet of contractors.
