..............reading with interest all comments but still feeling it's a con by various vested interests to have the opportunity to cash in on 'greenness' & produce even more saleable items.

After all, why is it that my local authority issues householders with extra plastic binsacks, green for cans, plastic bottles etc, pink for card & paper?

Surely it'd be 'greener' to have a reuseable bin to deposit this stuff, as is issued for garden waste & glass scrap
