I don't think I could cope with any more bins but having some extra bags along with our existing bins is doable if it helps with recycling and keeps so much of our waste going into land fill sites.
We have 4 wheelie bins. 3 full size ones, black for tins,glass and some plastics, green for all garden waste and a blue bin for paper, cardboard and tetra packs. We then have a half sized grey bin for any other waste that our council doesn't yet recycle. We have to have a chart to see when each bin is emptied in the 4 weekly cycle.
I know it sounds bad but now it's all got going it seems to be working well. Some areas can't cope with the physical presents of so many bins per house but different locations for storage of the bins and/or different sizes of bins for groups of houses can be arranged.
