Invention Reference Number
Oak Ridge National Laboratory has developed a thermally stable, scalable organocatalyst for chemical recycling of diverse plastic waste streams. The catalyst enables selective breakdown of certain polymers, including those in mixed or contaminated waste, into high-purity chemical building blocks for reuse. This technology addresses current recycling limitations by providing an efficient, cost-effective solution for processing plastics that are challenging to recycle mechanically, supporting a circular plastics economy.
Description
This invention features a robust, non-metal-based organocatalyst designed to deconstruct multiple types of plastics—including those found in mixed and composite waste—into their original chemical components. The catalyst’s temperature-controlled reactivity enables sequential breakdown of different polymers in a single system, facilitating separation and recovery without damaging inert materials. Its high thermal stability allows processing at elevated temperatures, making it effective for diverse and contaminated feedstocks that typically resist conventional recycling. Scalable production methods, combined with low-cost, readily available starting materials, make this catalyst commercially attractive for large-scale deployment. By recovering monomers and oligomers from plastics otherwise destined for landfill or incineration, the technology reduces dependency on virgin petrochemicals, lowers waste volume, and supports integration into existing recycling infrastructure. This advancement provides industry with a versatile pathway to process plastics from packaging, textiles, automotive, and other sectors.
