Twenty years ago, recycling was something you onnly did if you were really interested in being "green". Today, recycling is a normal activity for families all aroung the UK. Local councils make it easier for families to recycle by collecting materials from their houses. They even give them two different bins, so families can separate their rubbish from their recycling.

Recently, some local councils have decided to do even more; they are putting computer chips inside the rubbish bins they give to families in their area. The chips measure the amount of rubbish in the bin and also give information about the kind of materials in the bin; paper,glass, metal. In other words, if the family throws away these materials instead of recycling them, the council finds out. And when this happens they write a letter to the family asking them to be more careful about recycling.

The councils say their main aim is education. "If you regularly have problems putting the wrong items in your bins, we will simply provide guidance and possibly come out to visit you", they claim. But many people think that putting computer chips in bins is like having "bin police", and they are not happy about it!
