项目摘要

The broader impact/commercial potential of this Small Business Technology Transfer (STTR) Phase I project is the acceleration of a new technology for the destruction of toxic per- and polyfluoroalkyl (PFAS), widely used in firefighting foams and consumer goods. However, they are environmental pollutants, highly toxic to human consumption, and hard to destroy. PFAS do not decompose naturally and are poorly broken down by incineration. Widespread contamination of soil, groundwater, and drinking water at sites near airports, military bases, and manufacturing sites is driving an effort to remove and destroy PFAS toxins. This project will advance a technology for destruction of PFAS-rich wastes in an energy-efficient, scalable, easily deployed manner. This STTR Phase I project seeks to leverage advanced manufacturing techniques and novel, corrosion-resistant alloys to advance the hydrothermal alkaline treatment (HALT) process for the destruction of PFAS. Hydrothermal processing has historically been plagued by challenges with corrosion and component lifetimes, requiring the use of expensive alloys, replaceable system components, and/or elegant chemical corrosion prevention strategies. However, hydrothermal processes are some of the most effective and efficient technologies for destroying hazardous wastes, such as PFAS. Successfully mitigating the material corrosion challenge would lead to more widespread adoption of hydrothermal processes for waste disposal. This project will leverage advanced manufacturing techniques to test the performance of several corrosion-resistant materials under the harsh, HALT conditions. Use of these corrosion-resistant materials may extend component lifetimes while reducing fabrication costs, reducing component fabrication and system maintenance costs.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.

这项小型企业技术转移（STTR）I期项目的更广泛的影响/商业潜力是，加速了一种新技术来破坏有毒的人群和多氟烷基（PFAS），该技术广泛用于消防泡沫和消费品。但是，它们是环境污染物，对人类的消费剧毒，难以摧毁。 PFA不会自然分解，并且被焚化分解不佳。在机场，军事基地和制造地点附近的土壤，地下水和饮用水的广泛污染正在推动去除和销毁PFAS毒素的努力。该项目将以节能，可扩展，易于部署的方式推进一项技术，以破坏PFA的富含PFA的废物。该STTR I期项目旨在利用先进的制造技术和新颖的耐腐蚀合金来推进热液碱性处理（HALT）过程，以破坏PFA。历史上，水热处理受到腐蚀和零件寿命的挑战，需要使用昂贵的合金，可更换的系统组件和/或优雅的化学腐蚀预防策略。但是，水热过程是破坏危险废物（例如PFA）的一些最有效，最有效的技术。成功缓解材料腐蚀挑战将导致更广泛地采用水热过程以进行废物处理。该项目将利用先进的制造技术来测试在恶劣，停止条件下的几种耐腐蚀材料的性能。使用这些耐腐蚀的材料可能会延长组件寿命，同时降低制造成本，降低组件制造和系统维护成本。该奖项反映了NSF的法定任务，并认为值得通过基金会的知识分子优点评估来获得支持，并具有更广泛的影响标准。
