Tyre recycling is important business. Thousands of tyres end up in landfill each year, despite the fact that there are many things you can do with them. Since the 1990s old car and lorry tyres have been used to make non-slip surfaces and insulation, but more recently artisans in north Africa have developed techniques for making all manner of practical and attractive objects, such as planters and stools. Creative recycling at its best.
