Problem
Hard-to-abate industries face increasing carbon credit costs, while large volumes of industrial residues are disposed of annually without being utilized. The construction industry seeks alternative feedstocks with optimized carbon footprints.
Solution
Sequestra offers a technology platform that transforms industrial waste materials, such as steel slag, incineration ashes, and construction waste, into sustainable construction materials that permanently store carbon dioxide. Their accelerated carbonation technology (ACT) mineralizes CO₂ captured from industrial flue gas within these residues. The resulting carbonated material can be used as supplementary cementitious materials (SCMs), non-reactive concrete aggregates, or fillers, converting disposal costs into value. Sequestra's platform includes material analysis, advanced data interpretation, and industrial process technologies, providing a comprehensive solution for CO₂ carbonation.
Target Audience
Sequestra targets hard-to-abate industries, such as steelmaking, construction, and waste incineration, seeking to reduce carbon emissions and disposal costs, as well as the construction industry seeking carbon-optimized alternative feedstocks.
