Living in a world without waste

The Mayor of Kamikatsu, a small community in the hills of eastern Japan, has urged politicians around the world to follow his lead and make their towns "Zero Waste".

He told BBC News that all communities could learn from Kamikatsu, where residents have to compost all their food waste and sort other rubbish into 34 different categories.

Residents say the scheme has prompted them to cut down on waste generally and food waste in particular.
