This Small Business Innovation Research Phase II project will develop innovative Osorb bioretention systems for enhanced remediation of stormwater quality. PI, Dr. Hanbae Yang, is using novel engineered glass-metal hybrid materials developed by ABSMaterials, Inc. of Wooster, Ohio to remediate environmental pollutants. Runoff control is an immediate and growing concern in the US. Stormwater often laden with nutrients, hydrocarbons, herbicides, and pharmaceuticals, damaging surface water and carrying persistent chemicals impacting humans and ecosystems. Dr. Yang's innovations for controlling runoff pollutants using engineered glass (Osorb)-metal composites mixed into bioretention systems have demonstrated effectiveness on atrazine, estradiol, endocrine disruptors, BTEX, and nutrients. The Osorb-metal composites combine two advanced remediation materials: (1) a high-capacity organosilica sorbent, Osorb, and (2) reactive embedded metals. The composite materials absorb pollutants by removing them from the water and degrade the pollutants within the glass. The key technology developments to be achieved in Phase II include (1) formula optimization field testing with clients, (2) formulation performance improvements, and (3) development of commercial and modular bioretention packages. Compared to older bioretention systems, it is expected some of these systems will see orders-of-magnitude improvement in effective stormwater pollutant remediation and set new standards for best management practice. The broader impact/commercial potential of this project conducted by Dr. Yang and ABSMaterials will include: (1) providing an entirely new tool for resolving combined sewer overflow challenges with green infrastructure for dozens of cities, (2) substantial reduction of environmental pollution with lower treatment cost for contaminated stormwater, (3) improvement of aquatic and human health, and (4) facilitation of green stormwater reuse. The EPA and state governments are mandating many stormwater programs control non-point-source/CSO pollution. The tools for runoff treatment are often lacking to meet stricter regulations. Developing economical and effective Osorb-based stormwater solutions will substantially reduce negative effects of runoff pollutants on human and aquatic health. Seattle estimates economic impact of uncontrolled stormwater runoff at $113M and plans to build 12,000 bioretention systems to reduce urban runoff by 16,000,000 gallons annually. Other cities, including Cleveland, Philadelphia, Baltimore, and New York, are developing similar green infrastructure strategies. ABSMaterials is further developing an integrated curriculum for science courses at high schools and colleges and providing internships and training experiences involving advanced materials and water remediation. The company expects to create 6 new full-time positions working directly on the commercial activities during the period of this grant.

这个小型企业创新研究第二阶段项目将开发创新的Osorb生物保留系统，以加强雨水质量的修复。杨汉培博士正在使用由俄亥俄州伍斯特市ABSMaterals，Inc.开发的新型工程玻璃-金属杂化材料来修复环境污染物。径流控制在美国是一个迫在眉睫且越来越令人担忧的问题。雨水通常含有营养物质、碳氢化合物、除草剂和药物，破坏地表水，并携带影响人类和生态系统的持久性化学物质。杨博士使用工程玻璃(Osorb)金属复合材料混合到生物保压系统中来控制径流污染物的创新技术已经显示出对阿特拉津、雌二醇、内分泌干扰物、苯系物和营养素的有效性。Osorb金属复合材料结合了两种先进的修复材料：(1)高容量有机硅吸附剂Osorb，以及(2)活性嵌入金属。这种复合材料通过从水中去除污染物来吸收污染物，并降解玻璃中的污染物。第二阶段将实现的关键技术开发包括(1)与客户进行配方优化现场测试，(2)配方性能改进，以及(3)商业和模块化生物固位组件的开发。与较旧的生物保育系统相比，预计其中一些系统在有效修复雨水污染物方面将有数量级的改善，并为最佳管理实践设定新的标准。杨博士和ABSM材料公司实施的这个项目的更广泛的影响/商业潜力将包括：(1)为数十个城市提供一种全新的工具，用于解决污水溢出与绿色基础设施相结合的挑战；(2)以更低的污染雨水处理成本大幅减少环境污染；(3)改善水生和人类健康；(4)促进绿色雨水回用。环保局和州政府正在强制许多雨水项目控制非点源/CSO污染。径流处理工具往往缺乏，无法满足更严格的规定。开发经济有效的Osorb雨水解决方案将大大减少径流污染物对人类和水生健康的负面影响。西雅图估计，不受控制的暴雨径流对经济造成的影响为1.13亿美元，并计划建设1.2万个生物保育系统，以每年减少城市径流1600万加仑。包括克利夫兰、费城、巴尔的摩和纽约在内的其他城市也在制定类似的绿色基础设施战略。ABSM材料公司正在进一步开发高中和大学科学课程的综合课程，并提供涉及先进材料和水修复的实习和培训经验。该公司预计在这笔赠款期间创造6个新的全职职位，直接从事商业活动。
