Sublime Systems will develop the first platform technology that uses electrochemistry to upcycle waste products and low-value minerals into valuable, CO2-neutral materials. The technology consists of an impurity-tolerant renewable electricity-powered electrochemical reactor. It generates strong acids and bases to separate, extract, and purify the elements contained in the input materials. The focus is on recovering magnesium, silica, and valuable metals from waste products (coal bottom ash and demolition waste concrete) and highly abundant but low-value mafic or ultramafic rocks. The process can produce starting materials for cements and several metals that can be used as CO2-free alternatives to conventional materials.
Sublime Systems’ technology is the first integrated solution for using low-value minerals and wastes to produce valuable materials while preventing environmental contamination and decreasing greenhouse gas emissions.
