Highest and best use of ultra-large end-of-life mine truck tyres are being brought about by a change to the model in which resources are mined, made into products, and then become waste. Just one of these giant tyres can weigh 4.5 t and stand 14 feet tall. Put five of the 63-inch variety into a thermal conversion plant, as is being done in Chile, and, gosh, out will come almost 2 000 litres of oil, something like 4 000 kg of high-tensile steel, of the order of 8 000 kg of carbon black – plus enough synthetic gas to fuel the plant doing the job for hours on end.
