sequestra funding news – Vienna-based sequestra Secures €1.1 Million in Pre-Seed Round Funding

The funds will help develop their globally patented technology that uses industrial waste to capture CO2 on a large scale.

The funding round included investors like the Carbon Drawdown Initiative, VSE Beteiligungs-GmbH, and Climate Founders, all of which focus on long-term, large-scale CO2 reduction.

It is creating a technology platform that permanently traps CO2 in industrial waste like steel slag, incineration ash, and demolition debris, while making these materials usable in construction. The platform combines analysis tools, data models, and industrial processes to offer customized solutions for the industry.

This innovation provides a sustainable way to handle waste and reduce CO2 emissions, tackling major challenges in heavy industry. Sequestra estimates its approach could cut global CO2 emissions by 4 to 8.5 billion tons annually, or 10-20% of total emissions.

The startup has joined several accelerator programs, including INiTS, the Vienna Business Agency’s Startup Grant, EIT Climate KIC Climate Launchpad, and EIT Manufacturing Venture Builders.

At the heart of sequestra’s work is its patented technology that uses data-driven methods to capture CO2 in mineral waste. A key milestone is building a rapid-testing facility that automatically analyzes small samples. This facility is expected to be ready by the end of 2025.

The team is also working on scaling up the technology for large-scale use. A key part of their plan is making the CO2-binding materials commercially viable for construction. To do this, sequestra is creating a role focused on ensuring these materials can be sold for construction use.

With this funding, it is moving closer to using its technology on an industrial scale, aiming to make heavy industry climate-neutral.
