As one of the world’s leading recyclers, Colas recovers and recycles materials and waste, including in particular demolition waste, from its infrastructure and industrial sites, at its 420 recycling facilities around the world and on its infrastructure projects. The Group is thus able to offer its customers circular economy solutions by developing recovery and recycling platforms as well as solutions for reusing materials. In this way, Colas helps preserve natural resources.

    Rising to the challenges of the circular economy across the Group

    Raising employee awareness, innovating and rolling out day-to-day solutions are all key drivers in speeding up the adoption of a circular economy. In particular, such initiatives help embed behavioral change not only at the individual and collective levels but also at industry level. 

    Investing in R&D to recycle materials

    The circular economy is and always has been a core area of research and development at Colas. The main focus is on in-place recycling of road surfaces, recycling of asphalt mix, the use of alternative materials such as organic residues, and research into additives and binders based on industrial co-products and by-products.

    Developing and promoting the use of recycling platforms

    One of the key challenges posed by the circular economy is the need for dense geographical coverage so as to be able to offer our customers local access to waste recycling and recycled materials. Colas is focusing in particular on developing recycling platforms and multi-activity platforms (quarrying, recycling, etc.).

    Offering our customers circular economy solutions

    Our work centers play a key role in the circular economy by: 

    • Limiting the amount of waste generated by each worksite
    • Promoting and offering operationally ready solutions for recovering and recycling materials
    • Drawing on environmentally friendly alternatives to offer solutions that preserve resources, such as in-place recycling
