Projet Interreg North West Europe: Cirmap

Every year, 65Mt of Recycled Fine Aggregates (RFA) are generated from the crushing of Concrete Construction and Demolition Wastes. Reusing RFA for concrete is not an option because of the rigorous construction standards.

The Interreg North-West Europe Programme decided to create the Cirmap project which aims to reuse the Recycled Fine Aggregates.

Reusing RFA in order to manufacture Urban, Memorial of Garden (UMG) furniture, which is less demanding on the materials used, is Cirmap’s mission.

In order to implement the process, the Cirmap team quickly established that the traditional precast concrete could not be used because of its high cost on a small-scale production.

However, 3D Printing would allow to manufacture customized pieces, to reduce their weigh and to produce onsite, which are usually located in limited access areas.

Cirmap will provide a new Mixture Proportioning Method for the design of 3DP mortars and a new Design Methodology for Customized Shapes to 10 manufacturers. The European project will also develop a Master Control Demand and a network which will create a new market and a circular economy loop.

At the project’s launch, 525t of RFA will be reused in 3D print products. The long-term objective is about 25Mt of RFA reused.

Neo-Eco's Role:

In the Cirmap project, Neo-eco will contribute to the selection of the appropriate materials for the study, define storage conditions and treatments of recycled materials.

Finally, thanks to our expertise in recycling and creation of circular economy loops, we will establish the economical and industrial feasibility of the project.

The Partners : The Interreg North-West Programme fosters transnational cooperation between public and private actors in order to make Northwestern Europe a key economical actor in innovation, sustainability and cohesion. Companies and universities (cf. Figure 1) from Northwestern Europe (cf. Figure 2) gathered to offer a second life to the RFA.
