Studies of recycled fuel oil for diesel engine extracted from waste plastics disposals

In developed countries there are so many plastics discarded from various kinds of industry and cities. One company, HoJo Unity, has developed a new recycled system and apparatus to liquefy these plastic disposals into fuel oils. These discarded plastics are melted and evaporated first, and their vapors are condensed and extracted after passing through various metal catalyzers for decomposition. These cycled oils are different to each other according to the kind of raw plastic, and generally they have high heating value with rather large density, and their total weights are about 60~80% of the raw plastics. The recycled oils are fed to diesel engines of several factories as a 30~40% blended fuels with gas-oil. Recycling of plastics by this method above is a very good contribution to the energy and environmental needs of the Earth
