          Battery recycling: the EU and
In the stunning surroundings of the old Hungarian capital of Budapest,
alongside the shining River Donau, representatives from Europe’s bat-
   tery organisations, as well as delegates from battery producers and
  recyclers, came together to evaluate for the first time the implemen-
         tation of the 2006 EU Battery Directive. In this article, Recycling
                         International reviews the key points raised at the event.
