Water and sanitation

This chapter advances SDG 6 and 11 by exploring the technological landscape of water purification in India, focusing on strategies for treatment of wastewater as a potential water source.
This chapter advances SDG 6 and 11 by reporting on the various laws and policy governing water supply in South Africa as well as the current state of water and wastewater infrastructure in South Africa.

This article addresses goals 7 and 9 by detailing how PVC is promising as a good holder for organic catalysts in treating wastewater to produce hydrogen.

One Earth: Perspective Volume 2, Issue 3, p 223-234, March 20, 2020

This article addresses SDGs 6, 12 and 14 by providing an ambitious scientific road map to define a new water planetary boundary consisting of sub-boundaries that account for a variety of changes to the water cycle.

Water footprint (WF) measures human appropriation of water resources for consumptive use of surface and ground water (blue WF) and soil water (green WF) and for assimilating polluted water (grey WF). Questions have been often asked about the exact meaning behind the numbers from WF accounting. However, to date environmental sustainability of WF has never been assessed at the sub-national level over time. This study evaluated the environmental sustainability of blue, green and grey WF for China's 31 mainland provinces in 2002, 2007 and 2012, and identified the unsustainable hotspots.
Chioma Blaise Chikere, 2017 second prize winner of the Green Sustainable Chemistry Challenge
In 2017, Chioma Blaise Chikere was awarded the second prize of the Green and Sustainable Chemistry Challenge. Her project “Eco-restoration of crude oil-polluted land in Nigeria” demonstrated how organic nutrients such as garden fertilizers and animal excreta can be used to degrade hydrocarbons, cleaning up the soils heavily contaminated by decades of oil spills and advancing SDGs 6, 13 and 15. Three years later, we caught up with Dr. Chikere to learn about her research journey.
The need for improved and safely managed sanitation facilities is acute in dense informal settlements in rapidly urbanizing areas. One of the key factors influencing the cost-effectiveness and reliability of service provision in informal settlements is the ability to optimize waste collection from latrines with variable use patterns that are spatially dispersed within an informal settlement. This study investigates how latrine sensors could be used to estimate waste fill levels and improve servicing efficiency for forty latrines in Nairobi, Kenya, supporting SDGs 3, 6 and 9.
The abundance of residual colors in the effluents discharged from textiles, tanneries, dyeing, food processing and numerous other industries across the globe, currently poses a grave threat to global environmental sustainability. Polymer enhanced ultrafiltration (PEUF) can be a cost effective and energy-efficient membrane separation process in the treatment of wastewater. This article supports SDGs 6, 12 and 14.
