The Waste Oil Recovery Industry is of several dozens Billion USD every year and is an important application segment for Activated Bleaching Earth. This category comprises Transformer oil, waste/used oil, Pyrolysis oil and Bio Diesels. Non-edible oil refining is requires removal of impurities like colour pigments, solid particulate matter and other unwanted substances.
Waste or used lube oil is one of the largest application segments for Bleaching earth. Lube oil finds major applications in the automobile industry. The refining of 42 gallons of crude oil produces around 0.5 gallons of lube oil while recycling of 42 gallons of used oil produces around 34 gallons of lube oil. Recycling of this oil is hence of great importance.
