||A novel low-temperature catalytic tertiary recycling process is being developed as an economical means for recycling waste plastics, and scrap composites and electronic materials. This process converts polymers into low molecular weight hydrocarbons at temperatures below 200 C. The hydrocarbons produced can then be reused as chemicals, fuels, or monomers. Metals, glass, ceramics, fibers, and fillers are separated from the hydrocarbons for further reclamation. A related technology has been commercialized on a large scale (100 tons/day) for recycling used tires. Initial laboratory tests show that commodity plastics, composite materials (thermosets and thermoplastics) , and electronic materials (cables, printed wiring assemblies, computer housings) can also be reclaimed. These early results indicate that this process can be applied on a large scale for reclaiming these materials that are currently not being recycled. Successful implementation of tertiary recycling will result in an economical means of reclaiming scrap organic materials for reuse, eliminating their introduction into landfills and saving valuable natural resources.
