BRIMSTONE COMMERCIAL, LLC (BRIMSTONE) WILL CONSTRUCT AND OPERATE A NEW PLANT TO COMMERCIALIZE A DEEPLY DECARBONIZED PROCESS FOR MAKING ORDINARY PORTLAND CEMENT (OPC) AND CO-PRODUCTS, INCLUDING SUPPLEMENTARY CEMENTITIOUS MATERIALS (SCM) AND SMELTER-GRADE ALUMINA (SGA). BRIMSTONE WILL DEVELOP A TRANSFORMATIVE TECHNOLOGY THAT APPLIES A CHEMICAL-BASED PROCESS FOR MAKING CEMENT THAT ELIMINATES PROCESS CARBON DIOXIDE (CO2) EMISSIONS ASSOCIATED WITH LIMESTONE PROCESSING. THE PROCESS ALSO INCLUDES THE PRODUCTION OF SCM FROM SILICEOUS RESIDUES TO REDUCE EMISSIONS ASSOCIATED WITH CONCRETE PRODUCTION AND HAS THE ABILITY TO INCORPORATE DIRECT AIR CAPTURE OF ATMOSPHERIC CO2 FROM MAGNESIUM-BEARING WASTE RESIDUE. THIS PROJECT WILL PRODUCE OPC AND SCMS FROM CARBON-FREE CALCIUM SILICATE ROCK USING A CLOSED ACID BENEFICIATION CYCLE. THE NEW PLANT’S SUCCESS, BY DEMONSTRATING A PATHWAY FOR ACHIEVING POSITIVE UNIT ECONOMICS FOR BRIMSTONE’S DECARBONIZED CEMENT PRODUCTION PROCESS, WILL DE-RISK THE BUSINESS M
