The broader impact/commercial potential of this I-Corps project is the development of a biologically active pervious structure to solve problems associated with runoff water that notably affects human health, soil quality, and the environment. The technology is a simple, yet more sustainable and multifunctional structure that can be applied to individual structures, community-based structures, and shoreline environments to minimize erosion, infiltration, and treatment of runoff water. The configuration and geometry of a biologically active pervious structure can be adapted to address individual and site-specific requirements for areas prone to runoff. Biochar can mitigate climate change by reducing soil emissions of greenhouse gases, where one ton of biochar can sequester three tons of carbon dioxide. Furthermore, introducing biochar in concrete block manufacturing can decrease carbon dioxide emissions as compared to producing concrete using 100% Portland type-I cement. The biologically active pervious structure has the potential to control erosion and improve runoff water quality through adsorption, biotransformation, and biodegradation which can prevent contamination of aquifers, waterways, and the environment.This I-Corps project is based on the development of a biologically active pervious structure. The biologically active pervious structure presents a viable solution to address several issues associated with runoff, including flow volume, erosional effects, contaminant deactivation, and greenhouse gas emissions. Multifunctional biochar (derived from invasive plants and waste agriculture biomass impregnated on a biologically active pervious structure) captures a wide range of nutrients, heavy metals, pesticides, herbicides, dyes, antibiotics, volatile organic compounds, and polycyclic aromatic hydrocarbons. The highly efficient and robust synergistic bacterial consortium immobilized on a biologically active pervious structure can bio-transform or biodegrade a wide range of parent and intermediate compounds sorbed on biochar, and bacterial exopolysaccharides. The biologically active pervious structure can be implemented for runoff treatment in individual buildings, urban communities, and coastal areas. Additionally, this technology can facilitate the capture and control of runoff volume before reaching surface water bodies, making it a viable option for the worldwide runoff capture/control industry.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.

这个I-Corps项目的更广泛的影响/商业潜力是开发一种生物活性透水结构，以解决与径流水相关的问题，这些问题会显著影响人类健康、土壤质量和环境。该技术是一种简单但更具可持续性和多功能的结构，可应用于个人结构，社区结构和海岸线环境，以最大限度地减少侵蚀，渗透和径流水处理。生物活性透水结构的配置和几何形状可以适应于易于径流的区域的个人和特定地点的要求。生物炭可以通过减少土壤温室气体排放来减缓气候变化，一吨生物炭可以隔离三吨二氧化碳。此外，与使用100%波特兰I型水泥生产混凝土相比，在混凝土砌块生产中引入生物炭可以减少二氧化碳排放。生物活性透水结构具有通过吸附、生物转化和生物降解来控制侵蚀和改善径流水质的潜力，可以防止对含水层、水道和环境的污染。生物活性透水结构提出了一个可行的解决方案，以解决与径流相关的几个问题，包括流量，侵蚀效应，污染物钝化，温室气体排放。多功能生物炭（来自入侵植物和废弃农业生物质浸渍在生物活性透水结构上）捕获广泛的营养素，重金属，农药，除草剂，染料，抗生素，挥发性有机化合物和多环芳烃。固定在生物活性透水结构上的高效和稳健的协同细菌聚生体可以生物转化或生物降解吸附在生物炭和细菌胞外多糖上的广泛的母体和中间体化合物。生物活性透水结构可用于单个建筑物、城市社区和沿海地区的径流处理。此外，该技术还可以在径流量到达地表水体之前促进径流量的捕获和控制，使其成为全球径流捕获/控制行业的可行选择。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
