A Composed Sustainable and Resilient Recovery Model from Waste Water

There has been a huge surge for natural resources like food, water, energy with the rapid rise in global population now-a-days. We need to remediate the significant risk happening due to excessive resource consumption, environmental pollution, climate change which is constantly affecting the resource management and security. However, emphasizing on current reduction of emissions, production of clean energy, nutrient recovery, it’s important to notice the unrealized potential of some sectors in term of sustainability and resilience. In this stressed situation, a sustainable infrastructure for waste water treatment could be a feasible approach towards the circular economy (CE). Nutrients and Energy recovery from waste water can be an exceptional opportunity for bringing the Environmental, Economic, and Social and Political benefits. Especially the waste water sludge, a high organic content provides a great opportunity to implement a composed sustainable model to recycle, reuse and recover some important products and energy. In this paper, we have summarized and reviewed different technologies of treating waste water to reuse it directly and indirectly, the environmental and economic implications of these different technologies, corresponding products in terms of waste to energy, nutrients recycling towards a circular and sustainable economy.
