Talking of innovation, here's the first innovation in waste disposal since the wheelie bin. Massive see through public bins so you can see how full they are and, more importantly, you can see whether they're for cardboard or plastic.
This also highlights the failure of the graphics. Don't get me started about the inconsistency of bin colour coding. Green meaning normal waste, garden waste or recycling depending which local authority you live in. Don't get me started on that because that's another blog post.
