Brimstone Commercial, LLC

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 Model and Support Net-zero Goals While Increasing Supply Resiliency in the Cement and Aluminum Industries. This Project Plans to Provide Tangible Benefits to the Community by Creating Up to 100 Family-sustaining Operations Jobs With Comprehensive Benefits, Engaging With Labor Unions and Supporting the Use of Negotiated Agreements for the Construction and Operation of the Facility. This Project Will Establish Early Two-way Engagement With Community Members Through a Community Advisory Council, Develop a Local Workforce Development Program, and Ensure Equitable Access to Benefits Through Partnerships With Minority Serving Institutions and Businesses Majority-owned or Controlled by Underrepresented Persons or Groups of Underrepresented Persons.
