So if I understand this scheme right, a standard 6 pack of cans are going to cost £1.20 more and I am going to have to collect them and store them separately to the other 4 separated rubbish categories I already have.

Then lug them all to a collection point to get the deposit back instead of placing them in my recycling that I already pay the council to collect every (other) week anyway.

Great, just great, how convenient.
