Plastic and tire pyrolysis involves subjecting plastic and tire to high temperature of 400 to 450 degree Celsius, in absence of oxygen. In case of oxygen is present plastic will start burning. During pyrolysis plastic and tire breaks down into smaller molecules of pyrolysis oil, pyrolysis gas and carbon black. Like plastic and tire, pyrolysis end products are also hydrocarbons. Pyrolysis is great way of recycling waste plastics and tires.
