ORNL Researchers Patent Low-Temperature Method to Convert Polyethylene Waste into Gasoline

Scientists at Oak Ridge National Laboratory have developed a novel chemical process that converts polyethylene plastic waste into gasoline and diesel-like fuels using inexpensive aluminum-based molten salts. Operating at temperatures below 200 degrees Celsius, the method achieves a 60 percent gasoline yield without requiring noble-metal catalysts, organic solvents, or external hydrogen. Published in the Journal of the American Chemical Society, the technology offers a potentially scalable alternative to high-heat pyrolysis, though researchers must still address the salts' sensitivity to moisture before industrial application.

Oak Ridge Lab Converts Polyethylene Waste to Fuel Using Low-Temperature Molten Salts

Researchers at Oak Ridge National Laboratory have developed a method to convert polyethylene waste into gasoline and diesel fuels using heated molten salts. The process operates below 200 degrees Celsius, avoiding the need for expensive catalysts or external hydrogen. While promising for industrial scaling, the method faces challenges related to water sensitivity.

Rib of Scotty the T. rex reveals 66-million-year-old healing wound via neutron imaging

Neutron imaging at Oak Ridge National Laboratory uncovered a vast network of mineralized blood vessels in the healing rib of Scotty, the largest Tyrannosaurus rex. The 66‑million‑year‑old wound began forming new vessels as it healed, and the salty marsh environment helped preserve these soft tissues until Scotty died. Researchers will extend the work to more fossils using neutron and X‑ray imaging to compare healing patterns across species.

Eco-Friendly Insulation Reduces Energy Bills.

Scientists at Oak Ridge National Laboratory have developed an eco-friendly alternative insulation made without harmful blowing agents. The nontoxic thermoplastic foam is made using hollow glass spheres and expandable polymer microspheres. The technology is readily adoptable by industry and opens avenues to develop safer composite foams for a variety of insulation systems. The need for ongoing research into insulation materials is ongoing, since space heating, cooling, and ventilation account for 35% of energy consumption for buildings — 29% commercial and 41% residential.
