Since early 2016, I have traveled to six major cities around the world (Jakarta, Tokyo, Lagos, New York, Sao Paulo and Amsterdam) to investigate how they manage — or mismanage — their waste. There are some remarkable differences. And a question emerges: Is this just garbage, or is it a resource?
The world generates at least 3.5 million tons of solid waste a day, 10 times the amount a century ago, according to World Bank researchers. If nothing is done, that figure will grow to 11 million tons by the end of the century, the researchers estimate.
