Problem
Industrial by-products, such as steel slag, are often landfilled, representing a missed opportunity for resource utilization and carbon sequestration. Existing carbon removal solutions can be energy-intensive or lack permanence, creating a need for scalable, long-term atmospheric CO2 reduction methods.
Solution
Alkali Earth upcycles industrial minerals, specifically steel slag, into precipitated calcium carbonate (PCC) through a closed-loop mineral processing system. This technology diverts waste materials from landfills and utilizes existing industrial infrastructure to facilitate carbon removal. The PCC produced sequesters atmospheric CO2 in a stable mineral form, offering a permanent solution for carbon reduction. The process is designed for scalability and provides measurable quantification of captured carbon.
Target Audience
Alkali Earth targets industries and organizations seeking verifiable and permanent carbon removal solutions, including those with significant industrial waste streams.
