ROFL!....no shortage or waste plastic not to mention 240 million used tires a year in the US alone. ...not to mention 2 gigantic plastic patches in the Pacific and Atlantic.

Pyrolysis Pyrolysis is the thermal distillation or decomposition of organic materials into oils, gases, and char. Pyrolysis has been proposed as a method to break down tires into usable end products including steel, oil, and carbon black. Despite many efforts to commercialize this technology, it is not economically viable in the US at present. The products of tire pyrolysis have limited marketability due to their low quality compared to virgin materials. High cost also inhibits this technology. Refining the end products to market specifications requires expensive equipment. The capital investment and operating costs usually make the products of tire pyrolysis too expensive. Although many pyrolysis projects have been proposed, patented, or built over the past decade, none have been commercially successful. No tire pyrolysis plants are currently operating in the US, however, this technology continues to be explored for expanded use. One example is a project funded by EPA's Office of Research and Development exploring the processing of tire pyrolysis oils to produce high value carbon black products: The Manufacture of Carbon Black from Oils Derived from Scrap Tires. cfpub.epa.gov epa.gov siliconinvestor.com
