Richard Dixon from Friends of the Earth Scotland tells us, ‘wasting lots of plastic, glass and aluminium is really bad for climate change because it takes lots of energy to create these materials and then we simply throw them away and they become a problem.

A huge boost in recycling for glass, plastic and aluminium will mean a large saving in energy, and that’s a large saving in climate change emissions.

Scotland tries to be a leading nation on climate change, and a deposit return system will help us to do that when it comes to our use of materials.”
