Holcim drives innovation from start-ups
The cement company Holcim is teaming up with three Swiss start-ups to promote innovation and sustainability in the construction sector. For example, recycled building materials should go into the 3D printer or CO2 should be stored in concrete.
The Zug-based cement giant Holcim is teaming up with three young Swiss companies, according to a media release . The aim is to advance innovative technologies in the construction sector and promote sustainability.
In cooperation with the Freiburg start-up Mobbot , for example, the integration of recycled building materials into 3D printing technology is to be promoted. Mobbot has developed the necessary 3D printing technology. Together with Holcim, it now wants to develop a concrete recipe that enables the use of recycled material in 3D printing.
Holcim has entered into another cooperation with the Bern-based company Neuustark . The spin-off from the Swiss Federal Institute of Technology Zurich ( ETH ) is developing a technology with which CO2 from the atmosphere can be permanently stored in recycled concrete. For this purpose, liquid CO2 is introduced into the demolition material. As part of the collaboration, neustark is investigating the CO2 conversion potential of the demolition concrete recycled by Holcim. In turn, Holcim is optimizing the concrete produced by Neustark. Holcim believes it is possible to integrate the neustark solution into its recycling process in the future.
The third collaboration between Holcim and the Ticino start-up company HeatNeutral has been agreed. This has developed an innovative combustion system that is intended to promote the decarbonization of production facilities. According to the information, the heating system works particularly efficiently and achieves an almost 100 percent combustion of fuels. This means that less fuel is required for the same output. In addition, the HeatNeutral system can also burn CO2-neutral oils such as vegetable oils, used cooking oils and biodiesel. Holcim is testing the solution in its concrete plant in Birsfelden BL.
