I would like to great a system that uses uv or infrared radiation harnessed from the sun to break the bonds holding polymers together, returning them to hydrocarbons. To be reused as lubricant in machinery ect. If the bonds can be created via processing then the bonds can be unbroken via processing. Plastics deteriorate in exposed sun light so there must be a way to decay them via uv or infrared radiation. This is why I am studying an engineering field.
