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.

29,9%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. |

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.

| 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. |
