Circular Economy


Circular Economy

In compliance with circular economy principles and under specific conditions, some natural raw materials used in the production of cement can be replaced with recovered materials deriving from other industrial processes. Where prevention, reduction, reuse or recycling of waste and by-products are not technically or economically feasible, the cement manufacturing process provides a more environmentally sustainable solution than waste-to-energy, incineration or landfill disposal, thanks to full energy and material recovery. In this way we can contribute to the reduction of global CO2 emissions.
Concrete production is also part of the virtuous process of circular economy thanks to the use of properly treated construction and demolition waste, such as, for example, recycled aggregates for the production of new concrete.

of the themal energy consumed comes from alternative fuels



Alternative fuels derives from waste materials that, after being examined and treated, can be used in substitution of fossil fuels.

Our best performance 
In Czech Republic 79.2% of our themal energy consumption comes from alternative fuels

Recovered material from other industrial processes can become a resource for us: waste from steel processing and production residues of sulphuric acid can be used instead of iron minerals; chemical gypsum obtained from the treatment of combustion gases from electrical power plants can replace natural gypsum; slag and fly ash can partially be used instead of clinker and pozzolan. 



 of our raw materials comes from recovered materials 


Our best performance
In Luxembourg 28.2% of our raw materials comes from recovered materials

of materials used for concrete production comes from non natural and recycled materials   



The non natural and recycled materials used in the production of concrete are waste materials from other industrial processes and aggregates from demolition waste, non-cast concrete or residue in concrete mixers. These can be used partially as a substitute for cement and natural aggregates.

Our best performance
In Poland 3.3% of materials used for concrete production comes from non natural and recycled materials
