Firm uses old tyres to produce biofuel


A GREEN start-up technology company has surprised scientists by producing a biofuel from old rubber tyres that can run turbo-charged diesel engines, while reducing emissions by 30 per cent.
Green Distillation Technologies (GDT) can produce 3000 litres of bio-oil from one giant seven-tonne mining truck tyre.
It hopes to increase production to more than 8 millions litres annually by mid-2017.
Director Trevor Bayley said the company used a technique known as destructive distillation to convert wasted, old rubber into renewable energy.
He said the idea was driven by a desire to reduce massive stockpiles around the world, which are growing at a rate of over a billion tyres a year.
“The process is emission-free and some of the recycled oil is used as the heat source for the production process.
“It begins by loading end-of-life tyres into a process chamber, which is evacuated of air and sealed.
“Heat is applied which acts as a catalyst for a chemical reaction, which sees the tyre destructed into different compounds, one of which is condensed into manufactured oil.”
The oil underwent rigorous testing at the Queensland University of Technology’s (QUT) Biofuel Engine Research facility. Although scientists there admitted they were a little sceptical at first. – ABC
