Grey Water Management (GWM) - Mechanism for treating grey water and black water together in densely populated areas preferably having low land implication.

Source

Source summary

Design combined greywater and blackwater treatment for densely populated areas with little available land. Centralised or community/household systems are possible, but space efficiency and safe reusable output are central. The source names reuse in agriculture, sanitation and industry and seeks reduced pollution and waste without prescribing one treatment technology.

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.
