So, for instance, people coming from Italy to London Heathrow and back would probably misplace some garbage because of the different colour code vs expectations.
|Milan Linate vs London Heathrow|
general waste: blue vs white
paper: white vs blue
platic: yellow vs red
But there's more: within the same city I found another colour code inside the one Company I visited.
Shouldn't we try to define a common colour code?
I know there might be issues depending on the country (have a look at this infodesign to see what I mean), but I think that even a common colour code within a country would improve recycling habits a lot by leading to less misplaced garbage.
And recycle bins would be useful, then. :)
