Swiss Carbon Removal Pioneer Neustark Secures $69M to Fuel Global Expansion

Neustark, a pioneering carbon removal company from Switzerland, has secured an impressive $69 million in a recent funding round. This significant milestone for the climate tech sector was spearheaded by Decarbonization Partners, a joint venture between BlackRock and Temasek.

Additional support came from notable investors through debt financing, such as Blume Equity, Holcim, Siemens Financial Services, Verve Ventures, ACE Ventures, and UBS. This hefty investment stands out as one of the largest growth equity rounds in the carbon removal industry, emphasizing the critical role of sustainable solutions in combating climate change.

Neustark's cutting-edge technology converts demolition concrete into a permanent carbon sink. The company has already implemented this solution at 19 sites across Switzerland and Europe, efficiently capturing and storing CO2. With this new influx of capital, Neustark aims to broaden its reach into North American and Asia Pacific markets, expand its team, and enhance its offerings to meet the burgeoning global demand for carbon dioxide removal (CDR).

"We turn the world's largest waste stream – demolition concrete – into a carbon sink. In the last 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," said Johannes Tiefenthaler, co-CEO and founder of Neustark.

The startup's technology employs an accelerated mineralization process, permanently binding CO2 to recycled mineral waste. The resulting carbonated, recycled aggregate can be reused for building roads or producing new construction materials, ensuring the captured CO2 is stored for hundreds of thousands of years with minimal risk of reversal.

In collaboration with Holcim, Neustark plans to scale this technology globally, fostering the development of circular and low-carbon building solutions. The funding will also facilitate the construction of 40 new carbon capture and storage plants across Europe, supplementing the 19 currently in operation. Neustark's clientele includes major corporations such as Microsoft, UBS, and NextGen.

Meghan Sharp, Global Head & Chief Investment Officer of Decarbonization Partners, expressed her confidence in Neustark: "With carbon capture, utilization, and storage being one of our key investment focuses, we believe that we have found a perfect partner to help scale the industry—and ultimately its decarbonization impact—in the years to come. Neustark not only helps organizations integrate carbon removal to address their hard-to-abate emissions, but their solution also contributes to decarbonizing the construction industry."

Neustark's innovative approach is crucial for achieving the IPCC's goal of limiting global warming to 1.5°C. By transforming waste into a valuable carbon storage resource, Neustark addresses immediate environmental challenges and lays the groundwork for sustainable construction practices.
