00:00Scientists at Oak Ridge National Laboratory have developed a new way to turn plastic waste into fuel.
00:06The process targets polyethylene, one of the most widely used plastics worldwide.
00:11That includes common products such as plastic bags and cutting boards.
00:15In laboratory tests, the researchers converted the plastic at temperatures below 200 degrees Celsius.
00:21That is far lower than conventional plastic pyrolysis.
00:24Pyrolysis typically requires temperatures around 450 to 500 degrees Celsius.
00:30The new method uses heated molten salts containing aluminum chloride.
00:34These salts act as both the reaction environment and catalyst.
00:38The process produced a gasoline yield of about 60%.
00:41It also avoided precious metal catalysts, organic solvents, and external hydrogen.
00:47Scientists found that acidic aluminum sites help break long plastic chains into smaller fuel-like molecules.
00:53Simpler polyethylene chains tended to produce gasoline-like compounds.
00:57More complex chains generated diesel-like products.
01:01Researchers say the approach could eventually offer a new way to process difficult plastic waste.
01:06But one major challenge remains.
01:08The aluminum-based molten salts readily absorb water, reducing system stability.
01:13Scientists are now working to improve the process and determine whether it can be scaled for industrial use.
