Public procurement represents a significant share of Belgium's gross domestic product. Making circular solutions prevalent in such contracts can have a strong influence on the further transition to a circular economy.
However, contracting authorities have a hard time integrating circular requirements and practices into their specifications, due to, among other things, the lack of exemplary circular specifications and experience with circular construction, the difficulty of mixing works tenders with service tenders (in the case of product-service combinations), and the difficulty of mixing tenders with calls for tenders (e.g. in the case of recycled materials).
Through the CABRIO project, Blieberg A.C.E.'s ambition is to produce type descriptions that governments can use in their type specifications. The descriptions, in the form of paragraphs to be added, chapters ..., would be available for 5 circular ambition levels: from low-level (XS) to very in-depth (XL).
By creating these type descriptions, we hope that more public authorities will include circular criteria in their contracts, thus providing a great lever for the circular construction sector.

Some interim results of subcontracts have already been disseminated and received direct feedback at the request of governments or architectural firms. The output of this study is freely accessible, downloadable, and explicitly not part of the partners' trade secrets.
Dissemination also continues after the project ends. Thus, a number of seminars, lectures and press events are planned in 2023.
