ABSTRACT:
A method of recycling of oil filters utilizes a shredder and a thermal unit. The oil filters are shredded into metal and porous media particles. The shredded matter is placed in a thermal unit and heated. The heat will be sufficient to convert the porous media to an ash, but not sufficient to melt the steel. After heating for a sufficient duration, the shredded metal particles will be separated from the ash and recycled. The ash will also be recycled.
