DescriptionMineral carbonation, a technique that creates mineral carbonates to be used in construction materials from carbon dioxide (CO2), can pave the way for U.S. highways to act as carbon sinks. To do this, CO2 is captured from high-emission stationary sources and turned into precipitated CO2 (ppt-CO2) via a chemical process involving the use of an alkaline reactant in solution. The resulting carbonates are then combined with a binder and aggregate to produce the desired construction material, i.e., cement and, eventually, concrete. The ppt-CO2 materials may be further incorporated into conventional urban infrastructure as a novel method of carbon storage. Due to the expansive mileage of transportation systems in the U.S., highways could serve as effective long-term sinks for CO2 released from production and industrial emissions. Annually, 30 billion tons of concrete are produced from a combination of 52 billion tons of mineral aggregate and 4.1 billion tons of ordinary Portland cement; this means the implementation of mineral carbonation in place of current capture and storage methods has the power to store up to 1 Gigaton (Gt) or 1 billion metric tons of CO2 per year. State Departments of Transportation (DOTs) and metropolitan planning organizations (MPOs) can incentivize the use of carbon-capturing materials for highway construction firms via a carbon credit system that pays back per unit of ppt-CO2 utilized in new and rehabilitated concrete roadways. We created a geospatial mapping and analysis tool using the ESRI ArcGIS Online software platform and a cloud-based application for determining optimal locations of buildings and roadways that incorporate ppt-CO2. We demonstrate the above state of the science review for a case study in New Jersey using ESRI ArcGIS maps, analysis steps, and instant web apps for suitable building sites. The geospatial mapping and analysis tools developed in this study will enhance and optimize location planning and rollout for carbon capture and storage in highways and other structures within the built environment.
