Cleaner Diesel Gathered From Recycled Tyres

Old tyres can now be completely recycled and transformed into diesel engine oil with lower emission. This is a much better alternative than dumping them into stockpiles that are dangerous as well as high risk for fire. These stockpile sites are also used by mosquitoes as a breeding ground which will spread life threatening diseases such as dengue and malaria.

The tests were conducted by mechanical engineers from QUT and they checked the oil that was extracted from the waste tyres. The process used in recycling was developed by a company from Australia called GDT or Green Distillation Technologies.

According to Richard Brown, a professor from QUT, and Farhad Hossain, a PhD student, they have tested the emissions of the oil as well as the output at the Biofuel Engine Research Facility of QUT.

Professor Brown shared that after they have combined the oil with diesel, they found out that it is able to produce fuel with lower emissions and there is no recorded loss on the performance of the engine.

Professor Brown also added that all over the world, 1.5 billion tones of tyes are being disposed of every year. In Australia alone, it is expected that the number of discarded tyres will reach by 55 million every year by 2020. It has been a big problem ever since on how to discard the old tyres without causing harm to the environment.

Discarded tyres that are sent to stockpiles present a health hazard anywhere it might be in the world. The latest Broadmeadows fire that happened in Victoria is a sad example of how hard it is to put out fire caused in tyre dumping sites and it resulted to a very high amount of toxic smoke.

Mr. Farhad shared that there were rigorous tests performed in order to check the oil. The tests were conducted by the engineering team from QUT which includes Dr. Tom Rainey, a process engineer, and Professor Zoran Ristovski, an expert in air quality.

They found out that recycled tyres purchased from dealers, such as Gold Coast Tyres, can produce oil that has 30 per cent lower nitrogen oxide and lower particle mass.
