There is a Japanese word, mottainai, that carries the sense of regret over discarding something still useful, and a small mountain town of 1,500 people in southern Japan has spent the past twenty years building a municipal system around it, requiring residents to sort their household waste into 45 separate categories and achieving an 81 per cent recycling rate against a national average of 20 per cent.
The town is called Kamikatsu. It sits in the mountains of Shikoku, the smallest and least populated of the four main Japanese islands, about an hour's drive inland from the prefectural capital of Tokushima.
