    Climate project establishes CO2 storage within the building materials cycle

    According to a press release, the climate protection programme run by zirkulit Beton AG in Kloten has now been officially registered as a project aimed at increasing carbon sequestration capacity. This makes it the first project for CO2 storage in circular concrete to be approved by the FOEN in Switzerland. The programme comprises several CO2 storage facilities operated in partnership with concrete manufacturers at various locations across Switzerland.

    As part of the programme, biogenic CO2 is captured from Swiss biogas plants, transported to recycled concrete plants and, there, brought into contact with granulate from demolition concrete in the storage facilities developed by zirkulit. The CO2 reacts with the cement paste contained in the concrete aggregate to form calcium carbonate and is thereby permanently bound in a mineral form. This aggregate is then used to produce circular concrete.

    “This creates a permanent carbon sink within a durable building material,” says zirkulit Beton AG, “a key lever on the path to net-zero in the building sector.” This underscores its commitment to actively contributing to the transformation towards a circular and climate-friendly construction industry.

    The programme is financially supported by the Klimarappen Foundation. Together with the partners of zirkulit Beton AG, it is funding the project as one of five national pilot projects for negative emission technologies and carbon capture and storage. Klimarappen is providing a total of 50 million Swiss francs for this purpose. Funding is provided under a multi-year supply contract for the CO₂ removals achieved through the programme.

  • Aarau as a future cleantech pioneer

    Aarau as a future cleantech pioneer

    On 18 March 2024, AEW Energie AG held a co-creation workshop in partnership with the city of Aarau and other key players, which served as a platform for the development of sustainable technologies. This initiative, which was carried out in close collaboration with the Aarau Economic Development Agency and the Hightech Zentrum Aargau as well as companies such as Jura Management AG and Swisscleantech, underlines the common goal of transforming Aarau into an innovative cleantech location. The workshop focussed on the promotion of technologies for CO2 reduction and the use of renewable energy sources.

    The Mayor of Aarau, Dr Hanspeter Hilfiker, and Marc Ritter emphasised the importance of sustainable innovations and Aarau’s role as a pioneer in this area. The focus was on the development of cleantech solutions, particularly with regard to carbon capture and storage and the promotion of renewable energy sources. This approach reflects AEW’s commitment to achieving carbon neutrality and promoting sustainable practices that offer both economic and environmental benefits.

    The workshop collaboration demonstrates the potential of collective efforts to solve complex sustainability challenges. The ideas generated will serve as a basis for future pilot projects that will further strengthen Aarau not only as an innovative but also as an attractive business location for companies and start-ups. This approach underlines the endeavour to promote cross-industry cooperation and develop innovative solutions for a sustainable future.
