Calera offers a solution to the scale of the carbon problem. Calera’s Carbon Capture and Mineralization technology with beneficial reuse has been called, “game-changing” by Carl Pope, Director of the Sierra Club. By capturing carbon into the built environment, Calera provides a sound and cost-effective alternative to Geologic and Terrestrial Sequestration. The process converts carbon dioxide (CO2) from the burning of fossil fuel into carbon-negative building materials, enabling the production of clean power, cement, fresh water and other products to promote sustainable growth. The process can capture other emissions as well, including sulfur dioxide, particulate matter, mercury, and other metals. In capturing CO2 and other emissions from raw flue gas, Calera’s carbonate mineralization technology utilizes solid and liquid sources of alkalinity, such as fly ash, wastewaters, and brines. The outputs of the process are clean air, fresher water, and solid materials that can be sold.
To reduce CO2 emissions into the atmosphere, it is critical to identify and deploy economically and environmentally attractive technologies. The deployment of capture and sequestration technologies that only involve cost for every ton of CO2 captured will be a significant burden to society and are likely unsustainable. Calera believes that environmental sustainability can be and should be coupled with economic sustainability with focus on clean technologies that are compelling stand alone economic business cases.
Calera developed a CO2 conversion to materials technology that captures and sequesters CO2 with a sustainable economic case. Using this technology, it is possible to produce construction materials that are “green” with superior performance characteristics, such as weight and strength. Because of the ability to generate reactive calcium carbonates with unique properties, Calera’s CO2 mineralization process is a rare technology where the business models exists today to make CO2 sequestration commercially attractive in certain applications. In these cases, the economic feasibility is underpinned by the actual sale of better products that contain sequestered CO2 as opposed to the price of CO2 itself.
