CO2 Mineralization Using Porous Carbon and Industrial Wastes to Make Multifunctional Concrete
Summary
This engineering project developed a CO2 capture and utilization technology using porous carbon and industrial waste materials to produce a low-cost, scalable concrete product. It is a carbon capture materials science paper unrelated to microplastic environmental contamination.
Along with substantial benefits and promises of carbon capture and storage (CCS) technologies, significant challenges exist in developing scalable materials and methods for capture and of CO2. The overarching objective of this project is to provide a system approach for developing a new CO2 capture and utilization technology using porous carbon and industrial wastes to make a low-cost, scalable and multifunctional concrete product. The objective of Phase I of this project is to develop and fine-tune activated carbons from different wastes such as plastic wastes to offer a cheap, abundant and scalable feedstock for CO2 uptake. The objective of Phase 2 is creating a facile protocol to develop a concrete prototype comprising CO2 adsorbed activated carbon (e.g. from plastic wastes), followed by product validation, life-cycle analysis, and bench-scale testing. The project objectives are designed to specifically obtain a final product and technology that directly addresses the main goals of the DOE’s CCS programs.
