turning residues into sustainable construction materials that store carbon dioxide forever
why it matters
hard-to-abate industries are projected to face 140 €/t carbon credit costs by 2030, totaling € 185 Bn in the EU ETS, underscoring the scale of the decarbonization challenge.
meanwhile, 11 Gt of industrial residues are generated and largely disposed of without further use annually, even as the construction industry urgently seeks carbon-optimized alternative feedstocks.
our overarching technological approach
accelerated carbonation technology (ACT) allows the storage of CO₂ captured from the flue gas of industrial plants in mineral residues, such as steel slags, incineration ashes, or construction waste.
The carbonated material binds the CO₂ in such a stable way that it can be utilized as a valuable secondary resource in the construction industry - the only accepted form of CO₂ utilization within the EU ETS.
„in theory, typical steel slags can bind up to 300 kg CO₂ per ton.
we are making this a reality.“
– Dr. Lukas Höber, Co-Founder of sequestra
permanent carbon binding
depending on the material, target customers can permanently sequester up to 300 kg CO₂ per ton of residue. Morever, disposal costs can be transformed into additional value by utilizing the carbonated material in the building sector.
potential applications are supplementary cementitious materials (SCMs), non-reactive concrete aggregates or fillers. Identifying, which routes are feasible for each individual material is one of the central aspects of sequestra’s analysis regime.

our vision
globally, the total CO₂ reduction potential of using industrial waste materials as carbon sinks and substitute primary resources with the carbonated material is estimated to be 4 Gt or 10 % of global emissions. The people behind sequestra are fully driven to unleash this potential and become a global frontrunner in this segment.
