The Small Business Innovation Research (SBIR) Phase I project aims to develop an innovative manufacturing technology for high efficiency, low cost nitrogen fertilizer from fly ash, which is a recycled material from coal power plants that may contain high concentrations of mercury and carbon. The traditional N-fertilizers are water-soluble compounds, resulting in significant loss of fertilizer and pollution of streams and ground water. At the same time, America's coal power plants produce more than 76.5 million tons of fly ash per year, and most of it is disposed of in landfills. The high mercury content in the fly ash makes the disposal more difficult and costly. In this project, the fly ash will be converted to high efficiency nitrogen fertilizer and the mercury in the fly ash will be recovered. The success of this project will lead to a high volume and highly technical application for fly ash and a value-added high efficiency low cost nitrogen fertilizer. Moreover, the projected production cost of this nitrogen fertilizer is lower than that of the traditional nitrogen fertilizer. The use of this new nitrogen fertilizer on farms will increase crop production profitability and prevent fertilizer loss and water pollution. By avoiding the landfill disposal of the fly ash, the coal power plants will save millions of dollars.

小企业创新研究（SBIR）第一阶段项目旨在开发一种创新的制造技术，从飞灰中提取高效、低成本的氮肥，飞灰是一种从煤电厂回收的材料，可能含有高浓度的汞和碳。传统的氮肥是水溶性化合物，造成了大量的肥料损失和河流和地下水的污染。与此同时，美国的燃煤电厂每年产生超过7650万吨的粉煤灰，其中大部分被填埋。粉煤灰中汞含量高，处理难度大，成本高。本项目将粉煤灰转化为高效氮肥，回收粉煤灰中的汞。该项目的成功将为粉煤灰和高附加值、高效率、低成本氮肥的大批量、高技术应用奠定基础。此外，该氮肥的预计生产成本低于传统氮肥。在农场使用这种新型氮肥将提高作物生产的盈利能力，防止肥料损失和水污染。通过避免飞灰的填埋处理，燃煤电厂将节省数百万美元。
