How can industrial by-products help remove CO₂ from the atmosphere?
In the research project “A passive-DAC system using alkaline by-products to achieve negative emissions”, Chalmers University of Technology, the University of Gothenburg, Boliden, Höganäs, Nordic DAC Group, Klimpo, and Torkapparater are exploring exactly that.
The project aims to develop a low-cost, passive direct air capture system using alkaline waste materials from industries like mining, metallurgy, cement, and steel. These sectors both emit CO₂ and generate the by-products needed to capture it – making them ideal partners in the transition toward scalable, climate-positive solutions.
In an interview series, we introduce the experts and innovators behind the project. You’ll hear directly from researchers, engineers, and industry leaders about their roles, ambitions, and how this work could impact future carbon markets.
These conversations highlight the power of collaboration in advancing carbon dioxide removal — and the potential for passive DAC to help hard-to-abate sectors cut emissions and contribute to climate goals.
