London

EVER since China announced last year that it no longer wanted to be the "world's garbage dump", recycling about half the globe's plastics and paper products, Western nations have been puzzling over what to do when the ban went into effect, which it did on Jan 1.

The answer, to date, in Britain at least, is nothing. At least one waste disposal site in London is already seeing a build-up of plastic recyclables and has had to pay to have some of it removed.
