The broader impact/commercial potential of this I-Corps project is the development of a technology to recover phosphate and ammonia in wastewater as struvite. Struvite is a slow-release compound fertilizer. This proposed technology may decrease the cost of wastewater treatment and improve the struvite recovery process. Struvite recovery from wastewater is a sustainable alternative to the industrial production of phosphorus fertilizers that have resulted in rapidly depleting natural phosphate rock reserves. As global supply chains of fertilizer have been disrupted, fertilizer prices have increased substantially, increasing the revenue of struvite recovery. Farming that does not use water-soluble fertilizers is anticipated to grow rapidly. Unlike the currently available organic fertilizers, the struvite fertilizers produced with this proposed technology have high nitrogen and phosphorus values.This I-Corps project is based on the development of mineral-based magnesium-based amendment materials and bio-based binding agents for cost-effective recovery of struvite from wastewater. When wastewater pH is raised and magnesium ions are supplemented in nutrient-rich wastewater, struvite precipitates form. This mineral is precipitated into granules in a crystallizer for product harvesting. The proposed struvite recovery technology uses minerals to recover phosphate and ammonia as powdery struvite, a natural fertilizer, and applies bio-based binding agents to quickly turn the struvite powder into granular organic fertilizer. The proposed technology integrates two low-cost minerals and a physical mineral activation method for simultaneous supplementation of magnesium ions and elevation of wastewater pH for formation of struvite powder. The discovery of bio-based binding agents for pelletizing struvite powder increases the production capacity. This technological may change the overarching strategy of wastewater resource recovery.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/商业潜力是开发一种技术，以恢复废水中的磷酸盐和氨水。田里是一种缓释的复合肥料。这项提出的技术可能会降低废水处理的成本并改善田径恢复过程。从废水中恢复田径是磷肥料工业生产的可持续替代品，导致迅速消耗天然磷酸盐岩石储量。由于肥料的全球供应链被破坏了，因此肥料价格大大上涨，增加了田径恢复的收入。预计不使用水溶性肥料的耕种将迅速增长。与当前可用的有机肥料不同，使用该提出的技术生产的田径肥料具有很高的氮和磷值。该I-Corps项目基于开发基于矿物质的镁的修订材料和基于生物的粘合剂，以从废水中恢复Storuvite的成本效益。当废水pH升高并补充富含营养的废水，冬星沉淀的形式时，镁离子被补充。 该矿物在结晶剂中沉淀成颗粒，以进行产物收获。 拟议的田径恢复技术利用矿物质来恢复磷酸盐和氨粉状植光（一种天然肥料），并采用基于生物的结合剂来迅速将板岩粉转变为颗粒状有机肥料。提出的技术集成了两种低成本矿物质和一种物理矿物激活方法，用于同时补充镁离子和废水pH的升高以形成板岩粉。发现基于生物的结合剂用于颗粒板岩粉末会增加生产能力。该技术可能会改变废水资源回收的总体战略。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子优点和更广泛影响的评论标准来评估值得支持的。
