This chapter aligns with goals 6 and 9 by highlighting improved sustainability practices in terms of preparation, lifecycle, and application of bionanocomposites, including their application in wastewater remediation, biomedicine, and agriculture.

This chapter aligns with Goal 11 and 6 by analysing the use of wastewater for irrigation, balancing positive outcomes and trade-offs. There is a large variation between developed and developing countries as well as among countries within different economic groups regarding safe management of wastewater.

This chapter aligns with Goal 6: Clean Water and Sanitation and Goal 13: Climate Action by discussing the role and challenges of wastewater irrigation in agriculture in response to declining freshwater resources.

This chapter aligns with UN SDG Goals 3, 6, and 13 by promoting clean water, reducing pollution, and supporting sustainable water management practices.

This chapter aligns with Goal 14: Life Below Water and Goal 6: Clean Water and Sanitation by describing advancements in the use of melt electrospun nanofibers for use in marine oil spill cleanup.

This chapter advances UN SDG goals 7 and 13 by critically evaluating the current status of waste-to-energy (WtE) processes to determine how best to move forward from a few successful WtE demonstrations to commercial-scale processes.

Drug resistance became widely recognized global threats in last two decades. Knowledge of drug resistance, development of new vaccines and medicines, public awareness program, government support (policies and incentive), development of new diagnostic tool, industrial support in medical research are the need of the hour that will help the mankind to fight back and deal with drug resistance and helps to support SDG3.

This chapter aligns with UN SDG Goals 3 and 6 by addressing the use of wastewater.

This chapter aligns with Goal 6: Clean water and sanitation by reviewing the role of nanostructured materials as a promising alternative to conventional methods and is effective in eliminating water and wastewater contaminants, such as inorganics (toxic metals), organics, and microorganisms.

This chapter aligns with SDGs 3 and 6, by providing applications of geospatial technologies to monitoring water quality.
