I was reading that up to 20% of UK recycled waste ends up in landfill because it is 'contaminated' . What is meant by that?. I must say, I am surprised it's not a lot worse than that. I have lived in Essex and Sussex and been recycling for many years but the instructions that the council supply for residents are sketchy and really don't help. For instance, how 'clean' should glass bottles be? Washing in hot soapy water involves extra cost and should be discouraged if all they need is a rinse; not specified. Plastic containers often have "widely recycled" written on them. How wide is "widely"? Does it matter? I would imagine that separating the various types of plastic could be expensive (labour intensive) but without sorting, the resulting mix might be totally useless or only good for low grade bags or thermal insulation. Why not educate / inform the public how to recycle effectively? Surely a bit extra in your landfill bin and a higher quality of stuff in your recycle bin would be better value, overall. And all councils seem to be different. That's bad for a start because the residents everywhere produce much the same waste. It's just lip service, a lot of the time and 'jobs for the boys'.
