Construction materials: a second life for marble sludge!

Construction materials: a second life for marble sludge!

The marble sludge recovery project, studied and developed by the Technical Center for Construction Materials (CETEMCO), has just been selected for the industrialization phase, in particular, the manufacture of sanitary facilities by the Hygimar company. Details.

New recovery prospects are opening up for marble sludge. At the end of the technical feasibility study of the various ways of recovering marble mud, in particular, in the manufacture of cement mortars, cement tiles and sanitary products, industrial application monitoring and economic cost study, the VBM project, for Valorization of marble sludge, studied and developed by the Technical Center for Building Materials (CETEMCO) has just been selected for the industrialization phase, in particular the manufacture of sanitary facilities by the company Hygimar.

What to optimize the management of the many emissions of particles in suspension in the air and other falls of heavy particles on the ground, the rights of way… “Thanks to this research and development work, new products will quickly be put on the market. We hope this can serve as an example for other models or products.

This news reinforces the signature that we have just made with our supervisory minister, and also reinforces the development plan and the vision of this plan, which is partly focused on innovation and R&D.

In addition, we are continuing to work in this area to see large reconstituted marble slabs that meet quality requirements, scratch-resistant, resistant and which do not deteriorate over time, “explains David Tolédano, president of the Federation of Building Materials Industries (FMC) and President of CETEMCO. While it is difficult to estimate the tonnage of marble sludge available, the president of CETEMCO insists that this sludge is “amply sufficient to create an industry and develop a number of high-end, diversified and quality products” .

Issues in terms sustainable development
The marble industry generates tons of marble sludge every year which pose real problems for the professionals in charge of their management. This sludge, which generally ends up stored in nature, generates environmental and health impacts that are difficult to measure.

Faced with this basic problem raised by the need to manage the marble sludge produced by the marble industry, the VBM project “Valorisation of sludge from the marble industry” was born, which was carried out in 2016/2017.

“These sludges being relatively abrasive, they cannot be discharged into the sewers. Their revaluation therefore avoids damage to nature, so this project has challenges in terms of sustainable development”, argues the manager.

It should be noted that the project, which is part of CETEMCO’s activities of general interest, has benefited from a financial contribution from the Ministry of Industry, Trade, Investment and the Digital Economy through the Support Fund for Technical Centers (FACET).

Recall that this project, presented by CETEMCO in partnership with the Hassan II University of Casablanca, is one of 13 innovative projects selected from 140 others as part of the “Transfer Tech 2021” launched by the Moroccan State.
