Living in Brum, wheelie bins are unknown ... one of the oft-quoted
complaints I hear is you need 1 for this, 1 for that, 1 for the other, to
deal with recycling.

Would it be possible to design a single bin, with compartments - probably
like an angled "V" in the side, so you can put bottles, paper, and
household into the same bin ... then the compactors would have a
corresponding mechanism to select the appropriate chamber for emptying ...
