Utilization of captured carbon dioxide (CO2) by converting it into valuable products, such as fuels, chemicals, plastics, and building materials is needed to balance the carbon budget through 2050 and beyond. This presentation will describe two breakthrough processes invented and patented by Rutgers University for the production of low-carbon composites that have applications ranging from electronics to construction. The first process, namely, Hydrothermal Vapor Synthesis (HVS), enables the production of inorganic oxides at temperatures <500˚C, which is up to 1000˚C lower than the temperatures of traditional pyrothermal reactions. The second process, called Gasassisted Reactive Hydrothermal Liquid Phase Densification (g-rHLPD, Fig.1), enables low temperature (<100˚C) densification by using CO2 as a reactant with anhydrous oxides for creating strong, dense carbonate-bound ceramics with outstanding physical and chemical properties. Composite materials produced with these technologies will be presented and compared with the incumbent materials to demonstrate the outstanding low-carbon future awaiting materials manufacturing
