As I've posted before people sort glass into the various colours, place
in in the nominated bins and then the truck comes along and it ALL gets
mixed up in the same load back to the 'recycling' plant.

My local bottle bank has two bins. One is labelled "Clear", and the
other is labelled both "Green only" and "Brown only". Obviously a
psychology experiment.

(The truck which collects them has two compartments)
