Imagine that when you throw away your rubbish you have to insert an identity card into the container, so the authorities know how much rubbish you produce and what percentage of it you recycle. It may sound unlikely, but it could become reality before long. In Catalonia, in fact, it is already being considered as a way of monitoring the amount of rubbish each citizen produces. “We have to remove the anonymity with regard to rubbish,” says the director of the Residue Agency of Catalonia, Josep María Tost, who criticises politicians for being “afraid” to introduce measures which may be unpopular but which go in the right direction. “It’s not going to kill anybody to recycle more rubbish” he says.
