Neustark, a company headquartered in Switzerland specializing in carbon removal, secured $69 million in a funding round to accelerate its expansion in the carbon dioxide removal (CDR) sector. The growth equity funding was led by Decarbonization Partners, a collaboration between BlackRock and Temasek, aimed at bolstering Neustark’s ongoing growth trajectory. This investment supports their goal to permanently remove 1 million tons of CO2 by 2030.

Climate technology growth investor Blume Equity was also involved in this funding round. These new investors are now joined by Neustark's existing supporters: Holcim, Siemens Financial Services, Verve Ventures, and ACE Ventures, all of whom are continuing their commitment. Additionally, UBS has contributed through debt financing. Neustark has a strategic partnership with Holcim to expand its carbon removal technology worldwide, facilitating the development of circular and low-carbon building solutions.

The Swiss company specializing in carbon dioxide removal (CDR) has created and implemented a proprietary solution that enables the long-lasting removal of CO2 from the atmosphere. This is achieved by capturing CO2 directly at its source and then securely binding it within mineral waste streams through an accelerated mineralization process.

Biogenic CO2 is captured from biogas plants in partnership, then liquefied and transported to recycling sites for construction waste. There, the carbon dioxide is injected into concrete granules obtained from demolished buildings or other mineral waste such as slag and slurry. Neustark’s technology initiates an accelerated mineralization process, permanently binding the CO2 to the pores and surfaces of the granules. The carbonated, recycled aggregate can subsequently be used in road construction or for manufacturing fresh recycled building materials. This mineralization process securely stores the captured CO2 for hundreds of thousands of years, with minimal risk of reversal.

In collaboration with construction recycling partners, Neustark operates 19 carbon capture and storage facilities in Switzerland, Austria, Liechtenstein, and Germany. An additional 40 plants are currently under construction throughout Europe, with a strong pipeline of future projects beyond that.

Neustark has successfully delivered close to 120,000 tons of carbon removal to date, positioning itself as one of Europe’s rapidly expanding companies in the carbon removal sector. Its clientele includes Microsoft, UBS, and NextGen. All projects are certified under the Gold Standard, guaranteeing rigorous third-party assessment and transparency in performance.

Neustark will leverage Decarbonization Partners’ expansive global platform and connectivity, which includes access to corporate and investor networks across North America and the Asia Pacific, as well as specialized decarbonization experts. Additionally, Blume Equity's robust climate network and expertise in scaling disruptive European climate technology firms will further bolster Neustark's capabilities. Together with Neustark's current investors, who bring substantial technology investment experience, this partnership will enable Neustark to expand its team and enhance its offerings to meet growing global demand for carbon dioxide removal (CDR) solutions.
