Development of advanced technology based desalination system (water purification) and bilge oily water separation system

Source

Source summary

Investigate replacements for shipboard reverse-osmosis freshwater plants whose output varies with seawater salinity and temperature, and for unreliable coalescer-based bilge-water separators. The source names carbon-nanotube and biometric-filter approaches for desalination studies, and centrifugal separation for viscous or particulate-laden oily water, aiming at a 5 ppm discharge oil content. These are technologies to study under operating conditions, not established replacements.

EV charging Infrastructure – Solutions for easier and faster charging of EV batteries

Make EV battery charging easier and faster across two-, three- and four-wheelers. The source frames long waits with slow or moderate chargers as an adoption obstacle and asks for charging improvements rather than specifying a particular charger architecture.

Municipal Solid Waste Management

Improve municipal waste collection, segregation, transport and disposal, or turn that waste into biofuels, recyclable biological products and other commercially usable products. The challenge calls for cost-competitive outputs as well as better handling of an overloaded waste system.

No. 181Problem statementEnergy and environment

E-waste Management

Improve e-waste collection, transport, processing and recycling, including recovery and reuse of valuable critical metals. The source frames discarded electrical and electronic equipment as both a disposal problem and a material resource; its historical rankings and recycling statistics are not current verification.
