After extraction, refineries process crude oil into different refined petroleum products including liquefied petroleum gas, gasoline, diesel fuel, kerosene, distillate fuel oil, jet fuel, lubricants, petrochemical feedstock, petroleum coke, and asphalt. Plastic production uses 8% of the world's oil production, with 4% used as feedstock and 4% providing the energy required for plastic production.
Envion focuses on reclaiming the valuable energy stored in plastic by converting it back into oil.
Since plastic is a derivative of petroleum, plastic possesses a commensurately high level of stored energy content. The energy density of polyethylene (PE), polystyrene (PS), and polypropylene (PP) is comparable to that of gasoline and is approximately 51% higher than that of coal. Unfortunately, this high level of energy literally "goes to waste" when plastic waste products are discarded. In 2007 the United States produced 58 million tons of plastic, from which 48 million tons of plastic waste entered the nation's waste stream.
