How is it feasible to convert plastics into fuel?
It's finally happening.
We may have a new way to tackle the growing problem of single-use plastics , which pose a colossal environmental threat, leaving million tonnes of plastic waste in the oceans each year. The new method involves selective recycling of polyolefins, converting them into liquid fuels such as diesel, jet and gasoline hydrocarbons, according to a recent study published in the journal Science Advances.
When combined with other recent advances in waste management and plastic conversion processes, this could be the start of a major change in the way we view plastic waste.

Converting plastics is 'an indispensable part of modern life'
Specifically, the yield of these converted hydrocarbons could reach % over Pt/WO/ZrO and HY in hydrogen at low temperatures of °C. This new process employs tandem catalysis, resulting in the initial activation of the polymer over Pt and further cracking over the acidic sites of WO/ZrO and zeolite HY, plus isomerization over the WO/ZrO sites, and intermediate olefin hydrogenation over Pt. The science is complex, but the facts are impressive.
This incredible process can be adapted to convert various forms of plastic waste, including high- and low-density polyethylene, polystyrene, polypropylene, and conventional polyethylene bottles and bags. It can even turn composite plastics into desirable fuels and light lubricants, according to the study.
If scalable to global levels, this could serve as an indispensable means of waste management, with vast potential implications for the prospects of global climate change. "Plastics are an indispensable part of modern life," the study authors wrote. "Global plastic production reached million tons in and is expected to increase to more than billion tons by "
"This growth is alarming if you consider the current management of plastic waste," in the United States, where more than % of plastics end up in landfills, with almost % incinerated and less than % recycled, explain the authors of the study including Sibao Liu of the Energy Innovation Catalysis Center at the University of Delaware (UD), Pavel A Kots of the UD Plastics Innovation Center, Andrew Danielson of the UD Department of Chemical and Biomolecular Engineering , and Dionisios G. Vlachos, from the Key Laboratory for Green Chemical Technology of the Ministry of Education, School of Chemical Engineering, Tianjin University, China.
How is it feasible to convert plastics into fuel?
Waste management is undergoing a great revolution
“ Unrecycled plastics generate large economic losses and emissions and harm the environment,” the authors wrote. Current attempts to reuse recycled plastics such as mechanical processing require large amounts of “virgin” material and “lead to lower value products.” We can assume that by "virgin," the equipment means non-recycled material, defeating the ecological appeal of plastic fuel conversions. The most robust and versatile means of combating plastic waste is chemical conversion, making this advancement in waste management very promising.
Developments in the area of recycling and waste management are booming. Just yesterday, researchers at Washington State University (WSU) revealed new technology capable of converting plastic waste into jet fuel in one hour. The cost-effectiveness of recycling plastic waste is crucial because it can help find ecologically benign ways to power aircraft, which are responsible for an outsized proportion of climate-altering carbon emissions.
