Turning Their Back on Black?

Lidl is reportedly going to stop packaging fruit and vegetables in black plastic containers 'by the end of the month' (https://www.theguardian.com/environment/2018/sep/21/lidl-to-stop-using-black-plastic-fruit-and-vegetable-packaging). This is claimed to be because such plastic cannot be recycled (it could, of course, be because the sorting devices used by some waste treatment centres don't respond to it?). There is a confusing enormous variation in what plastic items can and cannot be recycled in parts of the UK and it would help enormously if a greater degree of conformity could be legislated.
