Spent Earth Overview
Spent Bleaching Earth (SBE) is an activated bentonite clay residue generated during the decolorization stage of crude rice bran oil refining. Containing 20% absorbed vegetable oil, it functions as a high-calorific auxiliary fuel for cement rotary kilns and a binding additive for clay building bricks.
This circular eco-byproduct provides substantial calorific value from retained natural vegetable oil, making it an efficient alternative fuel source that reduces fossil coal dependency in industrial rotary kilns.
