I don't think dumping is really the right word here. As it says in the article, importers are illegally accepting the waste and making a good chunk of money from it. The private companies who are disposing of waste from Western countries are happy to pay these guys to get rid of it. Still they could try to check what happens to the waste, rather than just turning a blind eye. But when the mafia can dump nuclear waste in your own back yard, I guess it's hard to see what happens on the other side of the world to some plastic bottles...
