Plastic waste reverse engineered into clean fuel

Plastic waste reverse engineered into clean fuel

Engineering PhD candidate Songpol Boonsawat is hoping to revolutionise the way plastic is recycled by converting it into fuel that is cleaner and more energy efficient than petrol or diesel.

Songpol is developing a waste disposal system that turns household plastic waste, contaminated plastic waste and targeted plastic waste into fuel.

“This work could revolutionise how to sustainably eliminate plastic waste from landfill and reduce the contamination of plastic in nature, by closing the loop of the plastic product lifecycle” says Songpol.

“The plastic waste problem is a global issue.”

Reduction of plastic waste in landfill

If implemented across homes and councils across Australia, it could result in an 80 per cent reduction of plastic waste in landfill.

Songpol says there is huge potential for some councils to convert plastics into as much as 73 million litres of oil each year.

With 560 local government bodies in Australia each handling thousands of tonnes of plastic waste a year it also could be a revenue generating exercise.

The oil produced could generate electric power up to 7566 MW/year, with an Australian market value of at least $21 million from selling by-products.

“The vast majority of plastic waste still goes into landfill sites where it remains for hundreds of years,” says Songpol.

“The current traditional waste disposal treatment processes are not coping with plastics satisfactorily.”

Lower emission fuel oil

Songpol says the fuel generated from the plastic can be used for petrol or diesel generators, engines or even gas or jet turbines.

“We have been successfully producing quality fuels such as petrol, kerosene, diesel and fuel oil with lower emission and the technology also closes the loop of plastic product lifecycle compared to the current available waste disposal treatments worldwide,” he says.

“The fuel can be used effectively in systems like power generators or in machine engines.
Songpol works off campus from a laboratory in Grafton, NSW, supported Viro Solutions Group, NSW Environment Protection Authority and Clarence Valley Council.

    Great idea, not using Chemical? If yes this is great!!, small amont of CO2 is acceptable comparing to the plastic waste will last in landfill for HUNDRED YEARS+ the generation of secondary pollution from landfill.

    This is great technology for Government to invest in!!
