The broader impacts/commercial potential of this I-Corps project will lead to identification of customer segments and delineation of the value proposition for introducing novel technologies to capture and convert carbon dioxide (CO2) to value-added products bearing inorganic carbonates. The use of alkaline industrial residues as a feedstock to the process will lead to the recycling and reuse of these materials and reduce the waste that needs to be landfilled. Multiple customer segments and industrial sectors including CO2 emitters and generators of alkaline industrial residues are expected to benefit from the implementation of this technology. Through the NSF I-Corps Program, the team will identify the immediate need for this technology and the economic advantages that their technology will bring to U.S. manufacturing. This I-Corps project will result in significant insights into existing chemical and manufacturing processes for CO2 capture, conversion, and waste utilization. The technical challenges in existing processes, associated economics, and knowledge gaps in implementing novel processes for CO2 capture and utilization will be identified and discussed. The technology on which this project is based involves reacting alkaline industrial and mining residues and anthropogenic CO2 to produce value-added carbonate materials. These measurements occur at 25-75°C and involve the chemical solvents for CO2 capture. Preliminary research results show that high conversion of CO2 to calcium- and magnesium carbonates is achieved with internal chemical recycling of the solvent. In an alternative iteration, this approach can be used to chemically regenerate the solvent while producing useful products as opposed to thermal regeneration of the solvent. The morphologies of these carbonates can be tuned for specific applications including construction or filler materials.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该I-Corps项目的更广泛的影响/商业潜力将导致对客户群的识别，并划定引入新型技术以捕获和转化二氧化碳（CO2）的新技术，以实现具有无机碳酸盐的增值产品。酒精工业的使用将作为该过程的原料保留，将导致这些材料的回收和再利用，并减少需要垃圾填充的废物。预计该技术的实施将受益，包括二氧化碳发射器和发电机在内的多个客户群和工业领域。通过NSF I-Corps计划，该团队将确定对这项技术的直接需求以及其技术将为美国制造带来的经济优势。这个I-Corps项目将为二氧化碳捕获，转换和废物利用的现有化学和制造过程提供重大见解。将在现有过程，相关经济学和知识差距中实施新的二氧化碳捕获和利用过程中的技术挑战。该项目所基于的技术涉及对酒精的工业和采矿残留物以及人为二氧化碳的反应，以生产增值的碳酸盐材料。这些测量在25-75°C下发生，并涉及二氧化碳捕获的化学溶液。初步研究结果表明，通过溶液的内部化学回收，可实现二氧化碳向钙和碳酸镁的高转化。在另一种迭代中，该方法可用于化学再生溶液，同时生产有用的产品，而不是溶液的热再生。这些碳酸盐的形态可以针对特定应用（包括构造或填充材料）进行调整。该奖项反映了NSF的法定任务，并通过使用基金会的知识分子优点和更广泛的影响评估标准来评估值得支持。
