ABSTRACT:
The present invention provides an economic process which utilizes biodiesel and other high boiling esters containing short alkyl groups to produce liquid fuels from polymeric materials such as, for example, used tires. In a first embodiment, polymeric material is dissolved/suspended/dispersed in biodiesel upon heating to form a product containing between about 10% and about 35% by weight of polymeric material. At least some of the biodiesel is recovered and reused to dissolve/suspend/disperse additional polymeric material to form additional product. After a predetermined number of cycles, the accumulated product is used as a fuel. In a second embodiment, polymeric material is dissolved/suspended/dispersed upon heating in biodiesel to form a mixture containing between about 30% and about 90% by weight of the polymeric material to be used as heavy fuel oil to be burned as is or bulk refined. The present invention also encompasses the fuel formed by the processes described.
