Millions of tonnes of waste are produced every year by the construction industry in France. The Cirval industrial chair is therefore devoted to reducing the impact of the sector. The Fondation Mines-Télécom, IMT Nord Europe and a dozen SMEs work together as part of Cirval, developing concrete solutions to recycle, reuse and save resources. At the same time, Cirval works with institutions to adapt standards and facilitate the circular economy in the construction industry.
