Cirmap - CIrcular economy via customisable furniture with Recycled MAterials for public Places


Project Summary

In North West Europe, about 65 Mt of Recycled Fine Aggregates (RFA) are generated yearly from the crushing of Concrete Construction and Demolition Wastes and are disposed in landfills or in banks. In the meantime, 54 Mt of marine sands are extracted in zones where natural aggregate resources are missing, threatening fragile marine spaces. Reusing RFA in concrete would save natural resources.

However, no market exists for RFA owing to rigorous construction standards. RFA is a local resource, with large variability, which is not suited to mass production needing regular materials. But it could be used at a smaller scale, for the manufacture of products needing neither to comply with rigorous construction standards nor to possess high performances. About 5 Mt of RFA could be recycled into concrete for the manufacture of Urban, Memorial or Garden (UMG) furniture, being the starting point of a circular economy loop.

Traditional precast concrete cannot be used for small scale production because of the high share of moulds in the global cost (50 to 80%). However, concrete 3D Printing (3DP) allows manufacturing customized pieces that could be shown by customers as a banner of their identity. UMG furniture are always located in difficult to access zones, reducing their weight by shape optimization and printing them onsite would be easier. Moreover, online control of 3D Printing could be used to compensate materials variability, providing an efficient tool for the valorisation of these resources.

Cirmap will provide a new Mixture Proportioning Method (MPM) for the design of 3DP mortars with RFA and a new Design Methodology for Customized Shapes (DMCS). A new Master Control Command (MCC) for concrete 3DP will be implemented for the equipment of 3DP machines, and an integrated mobile 3D printing unit will be developed for onsite 3D printing of UMG furniture. A Cirmap-network will also be created for lobby and dissemination, leading to a new market for the reuse of RFA. 5 Local Public Authorities in North West Europe will provide public places that will be equipped with 3DP customized furniture.

The CIRMAP Network

In the frame of the Cirmap project, a network is being created in order to gather all the potential stakeholders of the future industrial field that is intended to be created. Entering the Cirmap Network is free and will allow you to get in touch with the latest results of the project. You will be invited to join the Advisory Board of the project in order to share your views and interact with partners, sub partners and associate partners.

Whether you are a private company working on concrete manufacture, production of materials, design, 3D printing machines …, a local public authority interested in new developments in the field of recycling and design, a laboratory, a university … you are welcome to join the network.

Abstract of the CIRMAP Project

 

Cirmap will provide a new Mixture Proportioning Method (MPM) for the design of 3DP mortars with RFA and a new Design Methodology for Customized Shapes (DMCS). A new Master Control Command (MCC) for concrete 3DP will be implemented for the equipment of 3DP machines, and an integrated mobile 3D printing unit will be developed for onsite 3D printing of UMG furniture. A Cirmap-network will also be created for lobby and dissemination, leading to a new market for the reuse of RFA. 5 Local Public Authorities in North West Europe will provide public places that will be equipped with 3DP customized furniture.

 

Project objectives: CIRMAP aims at finding new opportunities for the valorisation of Recycled Concrete Fine Aggregate through 3D printing of customized shapes. P

Total budget : € 6.98 Million

EU funding : € 4.19 Million

Duration: 36 months (April 2020 – March 2023)

First pilot scale 3D printing of Interreg NWE CIRMAP's project

The first pilot scale 3D printing, within the scope of Interreg NWE CIRMAP, was successfully achieved in May 2021 at IMT Lille Douai (France)! This first 3D printing campaign was jointly led by two CIRMAP partners: ARMINES and Université d’Orléans. The cementitious ink used for printing was developed in the laboratory and contains 100% recycled sand coming from Belgium. The printed shape consisted of a 28 cm height square, and shows the good printability of the ink, as well as the good surface aspect of the mortar at the fresh state and at the hardened state. These promising results will allow to print more complex shapes in the future, suitable for urban, memorial and garden furniture uses.
