I assume you have one of those blue recycling boxes now.
It's nice to have one for recycleable plastic but why bottles only? Surely, the shape doesn't matter but the material? Why can't I put in e.g. those annoying blister packs that are made of PE?
It's probably the same idiotic reasoning why I can't put cardboard into the paper recycling bin.

On the subject of recycling/waste management, where in Cambridge can I get dispose of electronics/computer stuff where it is treated/recycled and not just dumped? I have an old car radio, two keyboards and two knackered CD drives to dispose of.
