Upstream from the construction and maintenance activity, Colas also does significant business in the production, distribution, sales and recycling of construction materials (aggregates, emulsions and binders, asphalt mix, ready-mix concrete and bitumen) across all its sites around the world. Some of these materials are used by the Group while others are sold to third parties.

Colas operates via a dense international network consisting of:

  • 478 operating quarries and gravel pits 
  • 151 emulsion and binder plants
  • 538 asphalt plants
  • 192 ready-mix concrete plants
  • 1 bitumen production plant (Malaysia)

In 2020, Colas' sales of building materials amounted to :

  • 89 million tons of aggregates sold (Colas share)
  • 2.1 million tons of emulsions and binders
  • 35 million tons of asphalt mix
  • 2.6 million cubic meters of ready-mix concrete
  • 1.0 million tons of bitumen

The Group’s global authorized reserves of aggregates (Colas share) are estimated at 2.7 billion tons, i.e., 30 years of sales (Colas share).

Colas is one of the top five global recyclers, all sectors combined. With 800 recycling facilities around the world, Colas recycled 17 million tons of materials and aggregates in 2020. Through recycling, Colas produced 7.8 million tons of materials, the equivalent of 9% of its total aggregate production, or the avoidance of the production of 28 medium-sized quarries. In 2020, 16% of asphalt aggregates were also recycled to recover bitumen, i.e. avoiding the production of a medium-sized refinery.

Colas also has a significant bitumen distribution business, particularly in North America, Asia and Australia, relying on a network of 71 bitumen storage terminals and a fleet of bitumen vessels, river barges and railcars.
