A joint U.S.–China research team has developed a single-step, low-energy method that converts mixed plastic waste—including PVC—into gasoline-range fuels and hydrochloric acid (HCl) with over 95% efficiency at room temperature and ambient pressure. Utilizing light isoalkanes—refinery byproducts—as hydrogen donors, this process dechlorinates PVC, captures HCl for reuse, and offers a scalable, eco-friendly alternative to high-temperature pyrolysis.
Key Highlights
Exceptional efficiency: Achieves >95% conversion of mixed plastics to liquid hydrocarbons and HCl in one step without heat.
Ambient conditions: Operates at 25–30°C and 1 atm, eliminating energy-intensive heating and pressurization.
PVC dechlorination: Safely removes chlorine, capturing HCl for industrial chemical production and preventing toxic byproducts.
Circular economy potential: Transforms waste plastics and refinery byproducts into valuable fuel and chemicals, reducing landfill burden and fossil fuel demand.
Scalability promise: Simple reactor design and mild conditions facilitate industrial adoption and retrofit of existing refineries and waste-processing plants.
