So how does the nation’s largest city go about getting rid of its garbage? And what is zero waste anyway? Since the term became a buzzword two decades ago, it’s been adopted as a goal by many cities around the world. In practice, however, “zero” is a goal that’s out of reach for even the most well-meaning cities. They can go far–even to 90% reduction of landfill waste–but the last bit requires a higher-level of change than cities can usually achieve, such as getting more industries to design their products for zero waste in the first place.
