In collaboration with the services of Limoges Métropole, a hot mix consisting partly of recycled and crushed porcelain has been put in place.

The first project consists of a pedestrian plateau and the second of a larger street (5000m2). Since other projects were carried out especially in Creuse.

The initial idea was to find clear, local materials to incorporate them in a coating in order to eventually reduce the intensity of public lighting and thus save money. The Limoges region is still endowed with porcelain manufacturers so we naturally turned to industrialists to recover their waste and offer them a second life to materials.

Today we collaborate with several porcelain manufacturers including Bernardaud, La Fabrique, Royal Limousin, Deshoulières etc ...

While waiting for the first results concerning the reduction of the luminous intensity, we can say that the aesthetic side has already convinced many of our customers.

Sustainable Development

    From table service to the road.

      Limoges, the French capital of porcelain, indirectly produces many scrap ceramic, removed from the sale due to manufacturing defects. Colas Limoges Agency, whose platform makes it possible to recycle numerous products, has set up a collection system for several porcelain manufacturers in order to reuse this raw material on its sites.


    The Colas Sud-Ouest laboratory in Condat (Haute-Vienne) has developed a hot mix formula, made up of 30% of porcelain granulates. Objectives: lighten the coating and bring an aesthetic touch to the pavement. Successful bet with thirty tons of "porcelain" mixes made on a pedestrian plateau of the Avenue du Midi, close to the old Limoges.

    Better visibility of the road and visual comfort

    Interest of the population for the reuse of an old and traditional resource

    Recycling of previously buried and landfilled materials

    Nothing to report

    Use up to 30% recycled materials

    Porcelain recycling in pavements

    Incorporation of crushed porcelain recycled in asphalt to reduce energy consumption.

    The materials are recovered on the platform of Condat sur Vienne.

    They are then treated by crushing and screening in order to obtain a product compatible with the use of bituminous mixes.

    Once this treatment is completed, the products are sent to the asphalt mixing plant and incorporated with other materials from quarries.

    Finally the bituminous mixture is transported to the site and implemented.

    The finished product is recyclable again at the end of the road's life.
