The broader impact/commercial potential of this I-Corps project is the development of a technology that can convert yard trimmings disposed as municipal solid waste (MSW; 35 million tons produced annually in the US), into an environmentally benign anti-icer through anaerobic digestion. The proposed anti-icer is a potent alternative to traditional deicers, as it may be applied to road surfaces before a snow storm hits the targeted area, eliminating the need for deicer operations to be performed during the storm. One of the most commonly-used anti-icers is sodium chloride (NaCl, salt brine). While salt brine typically has been used as an anti-icer on roadways and in airports, the use of the salt brine corrodes vehicles, bridges, and asphalt and is known to damage the surrounding environment. It is also known that salt brine has a high transport rate in the surrounding environments and low hold-over time. Organic alternatives to the salt brine in the market are calcium-magnesium acetate (CMA) and potassium acetate. However, these products cost about a $700-$1,000 per ton. Commercial potential of the proposed anti-icer will be evaluated as a cost-effective and environmentally benign alternative to its competitors. This I-Corps project is based on the development of an anti-icer road surface treatment. It is produced from simultaneous use of anaerobic digestion and accelerated bioleaching processes to form a liquid organic anti-icer from digestion of grass or any high protein plant substrates (green waste) co-digested with molasses or any other potassium rich organic material. The two simultaneous processes take place inside an anaerobic digester filled with green waste and molasses and water at optimum proportions and equipped with a recirculation system. In the process of anaerobic digestion, insoluble organic compounds are hydrolyzed and broken into simpler soluble organic compounds by the naturally occurring anaerobic bacteria present in the grass. During this process, acetate is produced, and through a reaction with potassium present in molasses, it forms potassium acetate, which may be used as liquid organic anti-icer. Preliminary results have shown that the proposed anti-icer may be effective at temperatures as low as 15˚F.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，该技术可以将作为市政固体废物（MSW;每年在美国生产的3500万吨）中处置的院子装饰转换为通过厌氧消化的环境良性抗菌。拟议的反鉴定是传统脱水剂的潜在替代方法，因为在暴风雪袭击目标区域之前，它可以应用于路面，从而消除了在风暴期间进行的脱水剂操作的需求。最常用的抗鉴定之一是氯化钠（NACL，盐盐水）。虽然盐盐水通常被用作道路和机场上的反饰物，但使用盐盐水腐蚀车辆，桥梁和沥青会损害周围环境。众所周知，盐盐水在周围环境中具有高运输速率，并且持有时间较低。市场上盐盐水的有机替代品是醋酸钙（CMA）和乙酸钾。但是，这些产品的价格约为每吨700- $ 1,000。拟议的反鉴定的商业潜力将作为其竞争对手的成本效益和环境良性替代品评估。这个I-Corps项目基于反鉴定道路表面处理的发展。它是由简单地使用厌氧消化和加速生物化过程而产生的，从而形成了与糖蜜或任何其他富含钾的有机材料共同消化的草的消化或任何高蛋白质植物底物（绿色废物）的液体有机抗菌。这两个简单的过程发生在一个充满绿色废物，糖蜜和水的厌氧消化池内，并以最佳的比例，并配备了再循环系统。在厌氧消化过程中，不溶性有机化合物被水解并被草中存在的天然厌氧菌细菌分解成较简单的有机化合物。在此过程中，产生乙酸酯，并通过与糖蜜中存在的钾反应，形成乙酸钾，可以用作液体有机抗菌。初步结果表明，拟议的反鉴定可能在低至15°F的温度下有效。该奖项反映了NSF的法定任务，并且使用基金会的智力优点和更广泛的影响审查标准，被视为值得通过评估来获得支持。
