We look at three solutions connected to the “three Rs” – reduce, reuse and recycle. The city of Brussels in Belgium is in the process of moving all 40 municipal nurseries over to reusable nappies – and have managed to do it without their staff kicking up a stink! Also energy companies around the world have found ways to encourage customers to reduce their consumption by making it fun, and lastly we meet Makafui Awuku in Ghana - a man on a mission to turn used plastic into school desks.
