The Economist, August 11, 1990 v316 n7667 p70(1) What can I do with this old tyre? (recycling tires) (Business) Full Text: COPYRIGHT Economist Newspaper Ltd. (England) 1990 THE greening of business means that A companies must pay more attention to how their products are recycled or disposed of. The surest way of achieving that will be to turn environmental problems into business opportunities. It is not going to be easy. Consider the problem of worn-out tyres. There are billions of them around. About 270m tyres are discarded every year in America alone, which has a stockpile of old tyres reckoned to total 3 billion. As in other car-mad countries, old tyres are turning into mountains because the time-honoured method of disposal throwing them on to a rubbish tip-is being restricted. Tyres decompose slowly, sometimes taking as long as 80 years to disintegrate. They are also bulky and they trap air, which unfortunately makes landfills unstable. Recycling will become more commercially attractive, according to a study by KPMG Peat Marwick McLintock, a firm of management consultants. To spur progress the consultants suggest that tyre distributors should impose a small charge on customers to help pay for the development of better ways of disposal, especially shredding. In some countries, like Japan (which wears out 80m tyres a year), old tyres already have to be shredded before they are dumped. If tyres are shredded finely enough they can be used in other products. A small market has already developed using rubber crumbs from old tyres in carpet underlays, sports surfaces and even for road repairs. With cleaner, more efficient incinerators, the consultants reckon the use of old tyres as an industrial fuel will increase too. Then there is retreading. This involves capping the casing of a worn tyre with a new tread. Retread tyres are frequently used on lorries; some operators have their tyres retreaded four or five times before buying new ones. But retread tyres suffer from a dowdy, second-best image in rich markets. The consultants reckon that improved marketing, along with better standards, could turn retread tyres into a "green" product. Now there's a challenge. Article A9318143
