Using Waste (Garbage and Effluent) to Power our Cities
Cape Town has an ever increasing waste problem, as I'm sure have most South African cities. Some European cities recycle and incinerate garbage to power their cities. Some use effluent as a fuel to power the water recycling and purification process, and generate electricity as a byproduct that is pushed back into the grid. This could be done per block making each block self-sufficient.
What would it take for South African cities to do the same? How does one build an industry out of waste?
