The broader impact/commercial potential of this I-Corps project is the commercialization of a technology that will allow up to 80% of the waste glass (silicon oxides) in the United States to be reused, diverting 5.6 million tons from the landfill. According to the EPA, 7 million tons of waste glass is sent to the landfill annually. The proposed technology uses a pozzolan, a cement replacement that commonly replaces 20% of the cement used in standard mixes with glass materials (here, silicon dioxide) in the manufacturing industry. Generally for every 1 ton of cement produced, 1 ton of carbon dioxide (CO2), a greenhouse gas, is released. This translates to one house foundation of cement producing the CO2 emissions equivalent of driving a car for 2.5 years. The EPA estimates that the cement industry produces 86.8 million metric tons of CO2 each year, exceeding emissions by the aviation industry. For every 5 tons of the newly developed cement replacement material used, the equivalent of one car is taken off the road in terms of CO2. At full scale, the concrete industry could see a carbon savings equivalent of taking 1.75 million cars off the road every year. This I-Corps project will explore the commercial potential and commercialization strategies for a new process to take waste glass from the recycling industry and turn it into a pozzolan called Pantheon™. Concrete is normally made from gravel, sand, water, and cement. Water and cement react to form calcium silicate hydrate, which is the glue that holds concrete together. A pozzolan is a cement replacement that commonly replaces 20% of the cement used in standard mixes in the concrete manufacturing industry. Currently, the most common pozzolan on the market is fly ash from coal power plants. Pantheon™ offers superior properties and performance. First, Pantheon™ has a 13.4% higher concentration of silicon dioxide, the active ingredient in pozzolans. Second Pantheon™ has 19% fewer impurities than fly ash. This results in a concrete that is less expensive, more environmentally friendly, and 11% stronger than what is currently on the market.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/商业潜力是一种技术的商业化，该技术将重复使用美国80％的废玻璃（硅氧化物），从垃圾填埋场转移了560万吨。根据EPA的说法，每年将700万吨废玻璃发送到垃圾填埋场。拟议中的技术使用Pozzolan，这是一种水泥的替代品，通常取代了制造业中使用玻璃材料（此处，二氧化硅）中标准混合物中使用的20％的水泥。通常，释放每1吨水泥，1吨二氧化碳（CO2），一种温室气体。这转化为一个水泥的一个房屋基金会，产生二氧化碳排放量相当于驾驶汽车2。5年。 EPA估计，水泥行业每年生产8680万吨二氧化碳，超过了航空业的排放。每5吨新开发的水泥替换材料使用，就二氧化碳而言，一辆汽车的相当于一辆汽车。全面，混凝土行业可以看到碳储蓄相当于每年乘坐175万辆汽车。这个I-Corps项目将探索一个新过程的商业潜力和商业化策略，以从回收行业中取出废玻璃，并将其变成一个名为Pantheon™的Pozzolan。混凝土通常由重力，沙子，水和水泥制成。水和水泥反应形成硅水合钙，这是将混凝土固定在一起的胶。火山灰是一种水泥替代品，通常取代混凝土制造业中标准混合物中使用的20％的水泥。目前，市场上最常见的火山灰是煤炭发电厂的粉煤灰。 Pantheon™提供了出色的属性和性能。首先，Pantheon™的二氧化硅浓度高13.4％，二氧化硅是Pozzolans中的活性成分。 Second Pantheon™的杂质比粉煤灰少19％。这导致混凝土的价格便宜，更加环保，比目前在市场上的混凝土高11％。该奖项反映了NSF的法定任务，并且使用基金会的知识分子优点和更广泛的影响审查标准，通过评估被认为是珍贵的支持。
