The greenest city in the world, depending on who you ask, might be San Francisco, California
, or Curitiba, Brazil
, or Copenhagen, Denmark, or Vancouver
, Canada. These cities and others like them
have freed their citizens from car-dependency, switched to clean
energy, and made room for green spaces that let everyone breath a little
freer. But one key function they’ve also worked hard on? How to deal
with their trash.
It’s convenient to think of the
trash can as a black hole into which scraps and discards and mistakes
disappear. But these cities know better. Producing more trash means
wasting more money and using up more resources that could be put to
better use. Here are a few lessons from some of the greenest cities in
the world on taking out the trash.
