@Kath9 That's so great that you can recycle things like bread tags, plastic lids and actually know what they get remade into.
In Canada there is a deposit on all drink containers, whether it's booze or juice and they have to be recycled.
I find that while a lot of people will separate the recyclables, it's washing or rinsing them out first that people like to skip.
While it doesn't look so nice as the way you have them labelled, I think that actually attaching a sample of what goes in each bin to the outside of the bin can help with people not mixing things up. A plastic bottle screwed to one bin, a tin can to another.
What would be cool is if they made recycling bins look like what goes in them. A container that's metal and looks like a big tin can ( you could even paint a Campbell's soup label on the outside), a plastics recycling bin shaped like a water bottle, and so on.
There was a shop in a Mexican town I lived in for awhile that sold Mexican blown-glassware. You could bring in your glass recycling, they weighed it out and gave you a credit slip that you could use to buy the glassware. What they collected got melted down and fashioned into new glassware.
