    New technology paves the way for virtually CO2-free cement

    Holcim has agreed to acquire a strategic stake in Capsol Technologies, a specialist in post-combustion carbon capture solutions based in Oslo. This was announced in a statement by the building materials supplier. The focus is on HPC (hot potassium carbonate) technology, an energy-efficient chemical absorption process for capturing CO2 from gas streams, combined with an integrated heat recovery system. Holcim intends to use this technology to promote the large-scale production of virtually CO2-free cement and meet growing customer demand for climate-friendly building materials.

    “By combining Holcim’s expertise in cement production and on-site CO2 capture with Capsol’s safe and efficient technology, we have an additional lever to drive decarbonisation and achieve profitable growth,” said Ram Muthu, Head of Operational Excellence at Holcim. “This strategic investment brings us one step closer to large-scale production of virtually CO2-free cement.”

    The investment was preceded by a CapsolGo demonstration project at Holcim’s Dotternhausen plant in Germany in 2025, where Capsol successfully tested its technology in an industrial environment. The investment expands Holcim’s portfolio of decarbonisation technologies within its open innovation ecosystem. Through Holcim MAQER Ventures, the Group’s corporate venture capital unit, Holcim has made 19 investments to date and reviews more than 500 start-ups in the field of sustainable construction solutions each year.

  • Investments in the circular economy and decarbonisation strengthen CO2 strategy

    Investments in the circular economy and decarbonisation strengthen CO2 strategy

    Holcim receives a grant from the EU Innovation Fund for another major cleantech project. This brings the number of Holcim’s EU-funded CCUS projects to seven. According to a press release from the building materials manufacturer, this new carbon capture and storage (CCUS) project at its site in Martres-Tolosane in south-west France is a highly scalable plant based on mature technologies and close partnerships.

    Holcim had already announced an investment of 100 million euros in the sustainability of this cement plant in 2017. Between 2021 and 2023, Holcim invested a further 200 million euros in the decarbonisation of its French industrial facilities and made a further 60 million euros available for its continuation in May of this year.

    According to Holcim, these investments will have a leverage effect on the development of new sectors and jobs in the field of the circular economy on the one hand, and in the medium term in the field of carbon capture, storage and utilisation on the other. To this end, a new pilot platform, a real industrial test centre for open innovation, will be built at the Martres-Tolosane factory. It will be dedicated to improving new CO2 capture technologies.

    “Holcim is well on its way to making net-zero cement and concrete a reality on a large scale in this decade,” CEO Miljan Gutovic is quoted as saying in the press release. “This support from the EU Innovation Fund is a testament to the strength of our engineering teams, the maturity of our technologies and progressive partnerships across the value chain.”

  • Bank aims for net zero by 2030 in its own operations

    Bank aims for net zero by 2030 in its own operations

    ZKB wants to reduce its operational emissions to net zero by 2030. Since 2010, the Cantonal Bank has already reduced its greenhouse gas emissions by around 70 per cent, explains Marit Kruthoff from ZKB’s Performance Mandate department in an interview on the Cantonal Bank’s blog. The overall goal is to continuously reduceCO2-equivalentemissions(CO2e) and increase operational ecological performance. ZKB aims to limit its operational emissions to a maximum of 1,800 tonnes ofCO2eper year by 2030.

    ZKB aims to eliminate these unavoidable residual emissions through its removal portfolio. This involves removing CO2 from the atmosphere and storing it permanently in plants, soil, oceans or cement, for example. ZKB is relying “on the combination of the three providers neustark, climeworks and Bioenergie Frauenfeld”, explains Kruthoff.

    Climeworks, a Zurich-based spin-off of the Swiss Federal Institute of Technology in Zurich, operates plants that remove CO2 directly from the atmosphere and permanently store the CO2 captured from the air. Bioenergie Frauenfeld, based in the capital of Thurgau, uses pyrolysis to produce biochar and gas from wood. The resulting waste heat is utilised as district heating. Neustark from Bern has developed a technology for storing CO2 in demolition concrete. All three companies achieve negative emissions with their technologies.

  • KVA Linth receives special prize for CO2 capture project

    KVA Linth receives special prize for CO2 capture project

    The Linth waste incineration plant(KVA Linth) has been honoured with a special award from InfraWatt. The association for the utilisation of energy from wastewater, waste, waste heat and drinking water, which is based in the canton of Vaud, recognised the Linth waste incineration plant’s project to build a large-scale plant for the capture and storage of carbon dioxide by 2029, according to a press release.

    Such CCS (carbon capture and storage) plants are suitable for filtering carbon dioxide from the combustion air and channeling it into specially constructed storage facilities. The CO2 captured in the Linth waste incineration plant is compressed and liquefied at low temperatures and transported away in tank wagons. An output of 90 percent is forecast for the capture plant at KVA Linth, which would correspond to around 15.5 tonnes of captured CO2 per hour. When the plant is completed in 2029, 120,000 tonnes of carbon dioxide can thus be captured and stored annually with 8,000 operating hours.

    The project is being developed together with KVA Linth and the Centre for Sustainable Waste and Resource Utilisation. All development steps will be made transparently available to all MSWI plants in Switzerland, which will then be able to implement the corresponding technologies.
