A large part of the binders used in the graphite industry for making " Green Blocks " are Coke Oven Volatiles or COV.
A considerable portion of these COV used as binders is coal tar.
During the baking process of the green blocks as a part of commercial graphite production, most of the coal tar binders are vaporised and are generally burned in an incinerator to prevent release into the atmosphere, as COV and coal tar can be injurious to health.
