The broader impact/commercial potential of this Small Business Innovation Research (SBIR) project is to help wastewater treatment plants become compliant with emerging environmental regulations, while saving energy and without adding cost. It has potential to reduce the amount of biosolids that need to be shipped off-site and landfilled by up to 85% as well as completely destroy odors and pathogens. As a result, the project may also enhance social justice throughout the country. Currently, low-income and disadvantaged communities inherit waste from other communities, sometimes very far away from where the waste originated. They inherit the stench, the vectors (rats, flies, birds) and toxins. For example, 7% of the biosolids produced by New York City end up in Alabama, via trains and trucks. People living near the landfills and along transportation routes no longer use their porch because of the stench. By improving the economics of a technology that destroys organics much better than state-of-the-art technologies, wastewater treatment plants will become cleaner, less malodorous and use less energy. Other markets could open as well including clean power and chemical manufacturing. Finally, the project may lead to increased hiring of employees over the next three years. This SBIR Phase I project proposes to create an affordable and reliable process to cleanly and completely destroy organic waste, extract more resources and energy from sludge and biosolids at wastewater treatment plants while considerably reducing the amount of biosolids that need to be shipped off-site for disposal. This objective will be achieved by improving a process that uses water contained within the waste to create a hyper oxidative environment. Similar processes use costly and hazardous pure oxygen, are extremely energy intensive, and are plagued with high maintenance cost. By making innovations in energy recovery, the use of air as an oxidant instead of oxygen is possible without the large cost associated with having to heat and compress an entire air stream- oxygen plus inert nitrogen. Once optimal technical conditions for energy recovery are identified, the project will enter the design and fabrication phases. The resulting new energy recovery module will be added to an existing system. The prototype will be tested for continuous operation. New insights into energy recovery will be gained, which will benefit the scientific community as a whole.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.

该小企业创新研究 (SBIR) 项目更广泛的影响/商业潜力是帮助废水处理厂符合新兴的环境法规，同时节省能源且不增加成本。 它有可能将需要运出场外和填埋的生物固体量减少高达 85%，并完全消灭异味和病原体。 因此，该项目还可能增强全国各地的社会正义。 目前，低收入和弱势社区从其他社区继承废物，有时这些社区距离废物来源地很远。 它们继承了恶臭、媒介（老鼠、苍蝇、鸟类）和毒素。 例如，纽约市生产的生物固体有 7% 最终通过火车和卡车运往阿拉巴马州。 由于恶臭，居住在垃圾填埋场附近和交通沿线的人们不再使用门廊。 通过提高比最先进技术更好地破坏有机物的技术的经济性，废水处理厂将变得更清洁、更少恶臭并使用更少的能源。 其他市场也可以开放，包括清洁电力和化学品制造。最后，该项目可能会导致未来三年雇用更多员工。 SBIR 第一阶段项目提议创建一种负担得起且可靠的工艺，以清洁、彻底地销毁有机废物，从废水处理厂的污泥和生物固体中提取更多资源和能源，同时大大减少需要运至场外处置的生物固体量。 这一目标将通过改进利用废物中所含的水创造超氧化环境的工艺来实现。 类似的工艺使用昂贵且危险的纯氧，能源消耗极大，并且维护成本高昂。 通过在能量回收方面进行创新，可以使用空气代替氧气作为氧化剂，而无需加热和压缩整个空气流（氧气加惰性氮气）所需的大量成本。一旦确定了能量回收的最佳技术条件，该项目将进入设计和制造阶段。由此产生的新能量回收模块将被添加到现有系统中。原型机将进行连续运行测试。将获得对能源回收的新见解，这将使整个科学界受益。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
