Sustainable construction
Sustainable construction materials with a small CO₂ footprint are playing an ever more important role for us and our customers. We use special additives in order to improve the CO₂ balance of the products based on our Portland cement.
These alternative materials, which are waste products from steel mills and coal-fired power plants, partially replace Portland cement clinker in the production of "composite cement". We have also been working for several years to develop alternative binding materials that almost completely eliminate the need for conventional clinker.
The use of by-products from other industries for the production of clinker and cement or the recycling of concrete from demolished structures enable us to manufacture concrete more sustainably.

Research and Development
Of course, at HeidelbergCement we are also working to develop new products. One of the areas of focus of the activities at our central research laboratory in Leimen, Germany, and our product innovation laboratory in Bergamo, Italy, was the development of products with a better carbon footprint and improved performance in terms of the energy efficiency of buildings. We have developed various alternatives to traditional cement with reduced environmental impact, such as Ternocem®, an innovative belite calciumsulfoaluminate ternesite cement, or composite cements with a significantly lower clinker content.
