A new method, developed by Northwestern University chemists, has made significant strides in plastic recycling by breaking down 99% of Nylon-6 monomers, the basic components of nylon. This process enables the transformation of nylon into more valuable products.
This advancement is particularly crucial for items like fishing nets, carpets, and clothes, which often end up in the environment, posing serious threats to marine life and ecosystems. Nylon-6, found in these items, is known for its robustness and longevity, making natural decomposition a challenge. As a result, it can persist for centuries, contaminating water sources and harming marine wildlife.
The newly developed catalyst from Northwestern University offers a rapid, clean, and complete solution to this issue. It efficiently decomposes Nylon-6 within minutes, without producing harmful byproducts and without needing toxic solvents, costly materials, or extreme conditions. This makes it a feasible option for widespread use.
This catalyst not only aids in environmental cleanup but also facilitates the conversion of Nylon-6 waste into more valuable products. The research, highlighting this innovation, was recently published in the journal Chem.
Senior author Tobin Marks from Northwestern, a renowned professor in chemistry and catalytic chemistry, along with his team, including Linda J. Broadbelt and Yosi Kratish, have focused on developing catalysts that can revert these polymers to their original form for reuse.
Nylon-6 is commonly found in everyday items like clothing and carpets, often ending up in landfills or oceans. It forms a significant part of marine pollution, with fishing nets made of Nylon-6 constituting a large portion of the Great Pacific Garbage Patch.
The novel catalyst developed in Marks’ lab utilizes yttrium and lanthanide ions. When applied to melted Nylon-6 samples, it disintegrates the plastic, returning it to its original monomers without leaving residues. This process can recover 99% of the monomers, which can then be upcycled into more valuable products. The catalyst also selectively targets Nylon-6, allowing for efficient recycling from mixed waste.
The study was supported by various organizations, including RePLACE, the U.S. Department of Energy, and the National Science Foundation. The innovation promises significant environmental benefits and paves the way for more sustainable plastic management practices.
