Roll on
Britons get through a staggering 40 million tyres every year. Some of these are re-treaded so they can be used again, while others are reincarnated as playground surfaces or shoe rubber.
Many tyres are burned as fuel in factories - the air's filtered as it leaves the plant to avoid any toxic fumes.
But every year 132,000 tonnes of tyres still end up in landfill sites. New EU legislation bans this from 2006, so we've got to find a new use for spare tyres.
