A groundbreaking technology developed by Oak Ridge National Laboratory (ORNL) is revolutionizing the treatment of mixed plastic waste, a type of waste that traditionally poses significant recycling challenges. In a world where nearly 80% of plastic waste ends up in landfills or pollutes our environment, this innovative process marks a significant stride in the global battle against plastic pollution.
The brainchild of ORNL’s Tomonori Saito and former postdoctoral researcher Md Arifuzzaman, this transformative technology hinges on the utilization of an exceptionally efficient organocatalyst. This catalyst enables the selective deconstruction of various plastics, including diverse consumer plastics blends. Notably, Arifuzzaman, currently affiliated with Re-Du, continues to contribute to this innovation as an Innovation Crossroads fellow.
What sets this approach apart is its environmentally friendly footprint. The production of chemicals from plastic waste consumes less energy and emits fewer greenhouse gases compared to conventional petroleum-based production methods. This environmentally conscious approach aligns with the global goal of achieving a net-zero society, as articulated by the scientific community.
According to Saito, the corresponding author of the study published in Materials Horizons, “This concept offers highly efficient and low-carbon chemical recycling of plastics and presents a promising strategy toward establishing closed-loop circularity of plastics.” [Reference: “Selective deconstruction of mixed plastics by a tailored organocatalyst” by Md Arifuzzaman, Bobby G.
