In an efficient and safe effort to save us from the ill-effects of plastic waste, Akinori Ito from Japan has developed a machine which converts plastic back into oil. The machine produced in various sizes, for both industrial and home uses, can easily transform a kilogram of plastic waste into a liter of oil, using about 1 kilowatt of electricity but without emitting CO2 in the process. The machine uses a temperature controlling electric heater instead of flames, processing anything from polyethylene or polystyrene to polypropylene (numbers 2-4). Comment: 1 kg of plastic produces one liter of oil, which costs $1.50. This process uses only about 1 kilowatt of electricity, which costs less than 20 cents!
