Abstract
According to a process for treating perfluorides in which a perfluoride treatment undertaker carries out decomposition treatment of perfluorides discharged from a manufacturing plant by using a perfluoride treating apparatus connected to said manufacturing plant, and the cost of treatment of perfluorides calculated according to the amount of perflorides treated by said perfluoride treating apparatus is communicated to the owner of said manufacturing plant, it is possible to reduce the cost required for the decomposition treatment of perfluorides which cost is to be defrayed by the product manufacturer.
