ORNL scientists close the cycle on recycling mixed plastics
Oak Ridge National Laboratory

Scientists at the Department of Energy’s Oak Ridge National Laboratory used carefully planned chemical design, neutron scattering and high-performance computing to help develop a new catalytic recycling process. The catalyst selectively and sequentially deconstructs multiple polymers in mixed plastics into pristine monomers. The new organocatalyst has proven to efficiently and quickly deconstruct multiple polymers — in around two hours. Such polymers include those used in materials such as safety goggles (polycarbonates), foams (polyurethanes), water bottles (polyethylene terephthalates) and ropes or fishing nets (polyamides), which together comprise more than 30% of global plastic production. Until now, no single catalyst has been shown to be effective on all four of these polymers.

In Journal of Applied Physics, researchers describe an acoustic metasurface that uses pingpong balls, with small holes punctured in each, as Helmholtz resonators to create inexpensive but effective low-frequency sound insulation. The coupling between two resonators led to two resonance frequencies, and more resonant frequencies meant the device was able to absorb more sound. At the success of two coupled resonators, the researchers added more, until their device resembled a square sheet of punctured pingpong balls, multiplying the number of resonant frequencies that could be absorbed.
