We all are well aware of the fact that growing plastic waste is one of the worst crisis our planet is facing today. It is estimated that every year, more than 8 million tons of plastic waste ends up in our oceans.
However, a new technology developed by researchers at the Purdue University could help transform the world’s plastic waste into a whole new source of useful products and clean fuels.
According to the researchers, this technology can convert more than 90% of polypropylene waste – a type of plastic that is commonly used for packaging and toys – into high-quality gasoline and diesel fuels in a matter of hours.
The conversion process uses selective extraction and hydrothermal liquefaction to turn the plastic into naphtha, a kind of flammable oil that can then be used as a feedstock for other chemicals or further separated into specialty solvents or other products.
The clean fuels derived from the plastic waste generated each year could satisfy 4% of the annual demand for gasoline or diesel fuels.
