New plant for the mineralisation of CO2 in Germany
Neustark has realised a second plant for the permanent storage of CO2 in demolition concrete in Kirchheim unter Teck near Stuttgart. Construction waste recycler Heinrich Feess GmbH & Co. KG can now mineralise 1000 tonnes of CO2 per year.
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.
