First, you need to go where everything starts in cement production: the quarries, from where the limestone and clay that give rise to cement and then concrete are extracted. With the recycling of some of these materials that is already being carried out today, there will be less and less need to go to quarries. And with ongoing energy use, the reduction in CO2 emissions will increase.

In a perfect future, it may not even be necessary to resort to quarries, just being able to reduce the volumes of concrete through greater optimization of works and reusing and recycling the materials that come out of the demolitions of buildings and infrastructures that are taking place. Ultimately, a cement factory could become a factory for recycling the materials that give rise to concrete: “It’s one of our dreams”, says Ângela Nunes, director of innovation at Secil, a cement company that has been part of the Semapa group since 1994.

Ângela Nunes is an engineer and has been at Secil for 35 years. The Expresso podcast about the most innovative and distinctive things being done by companies in Portugal came to the League of Innovators, to explain the innovations that your company has managed to introduce into the cement production processes and that today, it guarantees, the Outão factory, in the Arrábida mountains, is “one of the most sustainable in Europe”. But, he adds, the company wants to go further and make concrete not only a more sustainable material but also a more “humanized” one. “Concrete can feel us, it can heat the environment, charge a car, measure blood pressure, notify a doctor”, he adds.
Other topics you might hear throughout the conversation
We want concrete to be better, more sustainable, more humanized
Today, between 10% and 15% of the materials from which concrete is made come from recycling.
Concrete had some negative connotations, very heavy but it is a beautiful material. AND perhaps the second most used material by man after water
The podcast that tells us what is innovative and differentiating is being done by companies in Portugal. In the “League of Innovators”, Elisabete Miranda and Pedro Lima talk to managers, directors and professionals who tell us stories that conquered the market and are contributing to the economic transformation of the country and its image. They tell us about the victories that brought them here, but also about the anxieties, the competitors they envy, the managers they admire, the professionals they have and the profiles they need to hire. Every week, on Wednesdays.
