This is an idea I really like. Lush have introduced popcorn as an alternative to polystyrene chips and shredded paper in their packaging. 60% lighter than usual and you can pop it in the compost bin too. An added bonus is that they can now do away with plastic bags to protect the products from getting ink on them which will save 4.5 million bags a year. Gulp. I hope it catches on.
