The present rate of economic growth is unsustainable without saving of fossil energy. New alternative fuels which can be successfully incorporated in the existing automotive engines. Oil derived from waste plastics is one such alternative, which not only ensures long existence or service of fossil fuels but also assists in bringing down the hazardous impacts caused by the improper disposal of plastic wastes.There seven type's plastics available (polyethylene Terephthalate (PETE or PET), High density polyethylene (HDPE),Polyvinyl-Chloride (PVC),Low-Density-polyethylene (LDPE), Polypropylene (PP), Polystyrene or Styrofoam(PS), Miscellaneous plastic( includes: polycarbonate, polylactide ,acrylic, acrylonitrile butadiene, styrene, fiberglass, and nylon) ).In this work we focusing on the utilization of valuable energy of toxic non-biodegradable waste plastics to lucratively be used as an alternative fuel.
