Ask any city manager or mayor what their top priority is and you’re likely to get ‘solid waste’ as an answer. You would think in today’s age we would have solved the waste management challenge and moved on to the next slightly more glamorous municipal service. Not so; and more than ever cities now need to pick it up a notch on solid waste management.
Solid waste is still probably the world’s most pressing environmental challenge. In poorer countries, solid waste can use up to more than half of a city’s overall budget; around the world there are more solid waste workers than soldiers; and despite the more than $225 billion spent every year on solid waste, in many low income countries less than half the waste is collected in cities.
