Circular economy

In our vision the built environment is fully recyclable, with maximum recycled content. In line with this, we offer recycled solutions and explore ways to close the loop of sustainable sourcing, using and reusing of materials. By reusing waste for energy recovery and materials recycling, we help to address the global waste challenge and enable circular economy solutions.

A significant proportion of this amount comes from waste or recovered byproducts.This is one of the lowest levels of clinker content in the sector.
In 2018 we co-processed around 11 million tonnes of waste, providing 18 percent of our thermal energy demand for clinker.
We are already one of the world’s largest waste processors and aim to process 80 million tonnes of waste per year by 2030.

Replacing clinker with industrial byproducts

Replacing the clinker in our final cement products with alternative mineral components reduces the carbon intensity of the cement. Our operations use the byproducts of other industrial processes, such as fly ash from the power industry and blast furnace slag from the iron and steel industry, to replace clinker in the final cement product. We do this where it is geographically and economically feasible and where these materials are available.


Co-processing is a form of waste management that recovers the energy and recycles mineral content from waste such as spent solvents, used tires, waste oils, contaminated soils, industrial and sewage sludges and demolition material. 

Sustainable construction and solutions

We have developed a range of sustainable solutions, which in 2018 represented 11 percent of net sales. However, virgin aggregates are too cheap and the general perception of recycled concrete is poor. Another big hurdle is the lack of standards covering the recycling of concrete.
