The wastewater that flows through the world's sewers contains a wealth of resources that could be recovered. The traditional approach of looking at these streams as a "waste" to be disposed of rather than a "resource" to be recovered is no longer a sustainable solution. It is time to change the paradigm from waste management to resource recovery as the building block for a sustainable society. The proposed collaboration with the University of Sharjah (United Arab Emirates) will explore eco-friendly and economic technologies that can lead to sustainable sources of renewable energy, materials (e.g., polymers, nutrients), as well as efficient waste management techniques. It will initiate different projects and proof-of-concept studies for resource extraction from waste streams. The impacts include: a greater understanding of the role of microbiome engineering in recovering resources; enhanced resource extraction with high through-put from waste stream; and integrated lifecycle assessment and machine learning into Water Resource Recovery Facilities (WRRFs) to contribute to transformative wastewater treatment technologies. The proposed collaboration will focus on environmental impact categories that are most sensitive to Canadian ecosystems, including climate change, ozone depletion, and human toxicity. It will result in significant environmental, technological, and economic benefits. Long-term impacts of this research can lead to ground-breaking advances in wastewater treatment plant (WWTP) design that adopts WRRFs, thus facilitating the transition to a circular economy. The proposed research will help cement Canada's global reputation as a hub for environmental research and innovation and enabling the enhancement of place-based capacity training and technology transfer. State-of-the-art training enabled through this collaboration will increase the capacity of Canada's civil and environmental engineering industry, leading to job creation and fueling further economic impact.

流经世界下水道的废水含有丰富的资源，可以回收利用。将这些溪流视为需要处理的“废物”而不是需要回收的“资源”的传统做法已不再是可持续的解决办法。现在是时候改变从废物管理到资源回收的模式，以此作为可持续社会的基石。与沙迦大学(阿拉伯联合酋长国)的拟议合作将探索可产生可持续可再生能源、材料(例如聚合物、营养素)的可持续来源的环保和经济技术以及有效的废物管理技术。它将启动从废流中提取资源的不同项目和概念验证研究。这些影响包括：更好地了解微生物组工程在资源回收中的作用；加强从废流中高通量提取资源；将生命周期评估和机器学习整合到水资源回收设施中，以促进变革性的废水处理技术。拟议的合作将侧重于对加拿大生态系统最敏感的环境影响类别，包括气候变化、臭氧消耗和人类毒性。它将产生显著的环境、技术和经济效益。这项研究的长期影响可能导致采用WRRF的污水处理厂(WWTP)设计取得突破性进展，从而促进向循环经济的过渡。拟议的研究将有助于巩固加拿大作为环境研究和创新中心的全球声誉，并有助于加强以地方为基础的能力培训和技术转让。通过这一合作实现的最先进的培训将增加加拿大土木工程和环境工程行业的能力，创造就业机会，并进一步推动经济影响。
