Switzerland: Neustark has appointed Christoph Kisker as its Chief Revenue Officer. He will lead commercial functions at the company to target global growth. Kisker previously worked as the VP Global Sales (Digital Consulting) for software-as-a-service company Celonis. Before that he held the role of Assistant Manager at KPMG.

Switzerland-based Neustark is commercialising technology to store CO₂ from the air in recycled mineral waste such as demolished concrete. Its proprietary process captures CO₂ from biogas producers and then binds it into mineral waste such as demolition concrete via an accelerated mineralisation process. The company has rolled out its carbon removal technology at 19 sites across Switzerland, Austria, Liechtenstein and Germany. Holcim invested in Neustark in 2023.

Switzerland: Neustark has raised US$69m in a growth equity round to scale up its carbon dioxide removal technology. The funding, led by Decarbonisation Partners—a collaboration between BlackRock and Temasek—will support Neustark's aim to permanently remove 1Mt of CO₂ by 2030. Climate tech growth investor Blume Equity also joined the round, alongside existing backers Holcim, Siemens Financial Services, Verve Ventures and ACE Ventures.

Neustark has developed a technology that captures biogenic CO₂ at its source and utilises it in building materials through an accelerated mineralisation process. This method is currently applied at 19 carbon capture and storage plants in Switzerland, Austria, Liechtenstein and Germany, with 40 more under construction across Europe.

Johannes Tiefenthaler, co-CEO and founder at Neustark, said “We turn the world’s largest waste stream, demolition concrete, into a carbon sink. In the past year, we have already deployed our unique solution at 19 sites. This growth investment will take us into the next exciting phase of our mission, helping us to further scale our impact across Europe, enter new markets in North America and Asia Pacific, and develop new solutions to store even more CO₂ in mineral waste streams.”

Switzerland: Carbon capture and storage (CCS) equipment developer and supplier Neustark says it plans to more than double the number of its CO₂ storage sites in Austria, France, Germany, Switzerland and the UK to 34 from 14. Neustark’s process turns mineralised captured CO₂ and existing mineral waste streams into useful limestone. Building materials producers lease Neustark’s storage sites to produce reduced-CO₂ alternatives such as recycled concrete. The sites currently have a total storage capacity of 5000t. Existing customers include Holcim.

Neustark CEO Johannes Tiefenthaler said “Neustark is scaling up rapidly, and we’re well on track to achieve our aim of permanently removing 1Mt of CO₂ by 2030. Our global goal is a series of reliable, region-specific CCS facilities that can be replicated anywhere, offering immediate sustainability benefits to local supply chains.”

Germany: Switzerland-based CO₂ mineralisation technology developer Neustark says that it sees major potential for recycling concrete from construction and demolition waste (CDW) to produce carbon-negative products using its process in Germany. Neustark inaugurated its first German plant, and 12th overall, at Marzahn in Berlin in late 2023. Capital Online News has reported that the start-up estimates that Germany generates 60Mt/yr of CDW concrete, but only recycles 600,000t/yr (1%). This contrasts with international CDW concrete recycling rates as high as 15% in Switzerland and the US.

The start-up, founded at the Federal Institute of Technology Zurich in 2019, currently absorbs 10kg/t of CO₂ in its recycled materials, but aims to reach 60kg/t. Its investors include Holcim.

Switzerland: Holcim has invested in CO₂ mineralisation technology developer Neustark. Neustark aims to remove 1Mt of atmospheric CO₂ by 2030 and sequester it in recycled construction and demolition waste. The company’s technology achieved Gold Standard certification as a method of CO₂ removal in March 2022. Holcim says that its investment advances its group commitment to putting clean technologies to work towards achieving net zero.

Holcim’s Europe regional head Miljan Gutovic said "At Holcim, we are working to decarbonise building for a net zero future, and Neustark's technology helps us reach this goal. After the successful demonstration of Neustark's solution in Switzerland, we are ready to scale up this carbon removal technology globally."
