  • New plant for the mineralisation of CO2 in Germany

    New plant for the mineralisation of CO2 in Germany

    Together with its partner Heinrich Feess GmbH & Co. KG,Neustark has commissioned a plant for the permanent storage of CO2 in demolition concrete in Kirchheim unter Teck. The plant at the construction waste recycler in Baden-Württemberg is already the second plant realised by neustark in Germany, ClimateTech from Bern announced in a press release. Around 1000 tonnes of CO2 can be bound in demolition concrete here every year.

    Neustark’s technology works with CO2 generated during local biomethane production. It is captured directly and liquefied for transport. At the plant near Stuttgart, the CO2 is fed into the demolition concrete in an airtight silo. In a short time, it combines there in the form of limestone in the aggregate, writes neustark. The technology shortens the mineralisation process, which takes several decades in nature, to just a few hours.

    “We decided in favour of this innovative technology because it integrates perfectly into our concrete recycling and production process on site,” Walter Feess, Senior Director of the construction waste recycler, is quoted as saying in the press release. For Valentin Gutknecht, co-founder and co-CEO of neustark, the new plant is a further step towards ClimateTech’s goal of being able to permanently bind around 1 million tonnes of CO2 per year by 2030. “What we urgently need now is demand from the public sector for carbonated construction materials in building and road construction and corresponding legal regulations to support efforts towards greater sustainability,” says Gutknecht.

  • Berner Kantonalbank cooperates with Neustark

    Berner Kantonalbank cooperates with Neustark

    Berner Kantonalbank(BEKB) is promoting CO2 storage facilities in the Bern-Solothurn region. To this end, it has agreed a cooperation with the Bernese start-up Neustark, according to a press release. The aim is to support its innovative technology for the permanent storage of CO2 in demolition concrete. The aim is to remove around 1,000 tonnes of CO2 from the atmosphere in the BEKB economic area over the next ten years.

    Neustark, a spin-off from the Swiss Federal Institute of Technology in Zurich founded in 2019, is the first company in the world to put carbon removal through mineralisation in demolition concrete into commercial practice and set up a network of storage facilities, according to the press release. In the summer of 2023, the largest plant to date in the BEKB economic area was put into operation in Biberist, Solothurn. Further facilities in the region are being planned. “Through our cooperation, we are not only promoting innovative technologies to achieve climate targets, we are also contributing to the circular economy in the region and making it possible to permanently remove CO2 emissions in our own economic area,” BEKB CEO Armin Brun is quoted as saying.

    In 2022, BEKB’s operational CO2 emissions amounted to 1153 tonnes. These are to be further reduced through various measures. Through this cooperation with Neustark, the bank will permanently remove 100 tonnes of CO2 from its operational emissions in its own economic area every year from 2024. According to the information provided, these are the estimated residual emissions that are unavoidable for BEKB and cannot be reduced in the future.
