Rapid urbanization will exacerbate the current water issues many cities are facing, water scarcity, flooding, stormwater consent decree, aging infrastructure, wastewater treatment and disposal. We start to realize the traditional open-ended approaches in dealing with specific water issues is not efficient and unsustainable, especially facing the imminent challenges of climate change. For example, all domestic water uses are treated to potable water standards and water is used only once and then disposed of. The wastewater is treated as wastes to be eliminated. The stormwater is nuisance to be removed as quickly as possible. All comes with the investment of large amount of energy and materials, tremendous financial burdens and increasing environmental problems. While circular economy is happening in different sectors across the globe, as a part of it, water sectors are shifting from the paradigm of waste disposal to resource recovery viewing “waste” as a resource.
The complex water issues often are intertwined and cannot be solved by the traditional siloed management approaches. This special issue will explore the innovations in resource recovery front at the nexus of food, water, energy, material in urban water systems. Resource recovery in water systems spans all aspects from alternative water sources, water reuse, chemical energy recovery from wastewater, anaerobic co-digestion with food waste, heat recovery in wastewater, kinetic energy recovery from piping systems, nutrient recovery, stormwater recharge, green infrastructure, sponge cities, smart urban planning, etc. This issue will showcase the research that has the great potential to accelerate the retrofit and transition of the current water systems to more sustainable ones for more and more communities.
Topics of interests include, but are not limited to, original research that involves:
- Innovative technology for resource recovery (water, energy, nutrient, material, etc.)
- Alternative systems demonstrating the interdependence of the nexus
- Resource recovery adaptability in the climate extremes
- Integrated assessment metrics providing the holistic measure of system performance and tradeoffs
- Innovative financing for resource recovery projects
- Scalability of resource recovery solutions
- Social conceives of resource recovery applications
- Regulation and policy implications
