Grey Water Management (GWM)- Implementing low cost technical solutions to mitigate water contamination, especially removal of contaminants, before discharge into rivers and lakes.

Source

Source summary

Develop inexpensive, maintainable greywater treatment removing contaminants before discharge to rivers or lakes. Address chemical, microbial and heavy-metal contamination, preferably at source, with community/drain-end treatment also relevant for larger volumes. Accommodate varying contamination and environmental conditions and support scaling; no specific removal process or certified outcome is supplied.

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.

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.
