A global production network
Colas operates via a dense international network consisting of:
- 463 operating quarries and gravel pits
- 147 emulsion and binder plants
- 518 asphalt plants
- 174 ready-mix concrete plants
- 1 bitumen production plant (Malaysia)
In 2021, the Colas share of sales of construction materials amounted to:
- 100 million tonnes of aggregates (excluding Reclaimed Asphalt Pavement)
- 1.5 million tonnes of emulsions and binders
- 38 million tonnes of asphalt mix
- 2.9 million cubic meters of ready-mixed concrete
Bitumen production totaled 0.5 million tonnes.
The Group’s global authorized reserves of aggregates (Colas share) are estimated at 2.8 billion tons, i.e., 28 years of sales (Colas share), to which an additional 1.4 billion tonnes of potential quota share reserves is to be added.
The production of aggregates and ready-mixed concrete
After water, aggregates are the second most used raw material in the world, and a key resource for Colas’ construction and maintenance activities. Thanks to an international network of 463 quarries and gravel pits and 4,000 experts, Colas is positioned as one of the world leaders in the production of aggregates. This activity is an industrial sector in its own right since among the 100 million tonnes produced in 2021, at least 70% is sold to third parties. The Group also has 174 concrete plants, which enabled it to produce 2.9 million m³ of ready-mixed concrete in 2021. This activity is carried out sustainably and responsibly, with a simple ambition: one action in favor of biodiversity in each quarry and each gravel pit across the Group.
Recycling and Reusing Materials
Colas is one of the world's leading recyclers, all sectors and materials combined, thanks to more than 420 recycling units across the world. As part of its road construction and maintenance projects, the Group recycles and reuses waste and materials from deconstruction as well as waste from other construction professionals and other industries (waste mirrors, broken porcelain, shoe soles, etc.), thus offering a range of recycled materials to its teams and to third parties.
Colas operates as part of a genuine circular economy. In 2021, the total amount of waste and materials recycled by Colas led to the production of 8.5 million tonnes of materials, or the equivalent of 9% of the Group's total aggregates production. This amounts to savings equivalent to the production of 34 medium-sized quarries.
In addition, recycling asphalt pavement saves bitumen (a non-renewable petroleum product). In 2021, 16% of reclaimed asphalt pavement (RAP) was incorporated on average in Colas' global asphalt mix production: around 320,000 tonnes of bitumen were thus recovered, the equivalent of the bitumen production of a large refinery. The gain obtained by recycling is threefold: reducing energy consumption and greenhouse gas emissions; saving resources by reusing a non-renewable raw material (bitumen) and aggregates; savings for the customer, thanks to lower cost for identical performance.
A bitumen distribution activity
Today, a leader in bitumen transformation with some 151 emulsion and modified binder plants, Colas has a foothold across the entire value chain for bitumen, a key resource for the Group. As the world's largest buyer, the Group stores, transports and markets this raw material using a network of 71 bitumen storage terminals and a fleet of 8 bitumen tankers, 2 river barges and 200 railcars.
Colas operates in this segment in Asia (through the Thai subsidiary Tipco Asphalt, in which Colas holds a 31% stake), in Australia, in North America, and more recently, in Europe, Africa and the Middle East with the creation in 2020 of Continental Bitumen Ltd.
To secure its bitumen supplies and expand its bitumen distribution and trading business, Colas relies on Continental Bitumen Ltd, which supplies bitumen to Group units in its geozone (1.5 million tonnes of bitumen per year). Continental Bitumen boasts a network of 14 bitumen storage terminals and aims to expand its logistics network with 5 to 7 new terminals by 2025.
