It was very familiar to Australian car owners in the 50s and 60s, particularly if they had to take the tyre off the rim to repair a puncture.
A tyre with an inner tube was universal in the days when car tyres were made by the bias-ply method.
It was so called because the layers of rubberised cords were embedded in the rubber in alternating diagonal layers at a 55-degree angle to the rim.
But that technology was replaced by the radial method of tyre construction which are steel-belted with the ply cords radiating at 90-degrees to the wheel rim.
You may think an end-of-life tyre must be an old tyre and vice versa.
As you may know, we have created a world-first tyre recycling process to turn end-of-life car tyres into oil, carbon and steel.
Commercial operations and academic researchers alike are discovering that breaking down a vulcanized tire into materials of a high-enough grade to use in new, high-quality car tires is no easy task.
Exhaust emissions from oil from recycled tyres have been found to have thirty per cent less nitrogen oxide, which contributes to photochemical smog and lower particle mass than oil from fossil sources, but almost the same performance, according to research conducted by the Queensland University of Technology.
“No one knows just how many end-of-life car and truck tyres there are in Australia, but what we do know is that they are an environmental scourge,” says Craig Dunn the CEO of an Australian company that has developed a world-first process for recycling old tyres into oil, carbon and steel.
