PROBLEM TO BE SOLVED: To stably treat a waste plastic containing carbon fiber in a large amount in cement manufacturing equipment without causing reduction of the scavenging efficiency of a dust collector and without applying a special pretreatment for separating carbon fiber. SOLUTION: In the method of treating a waste plastic containing a carbon fiber by supplying an exhaust gas which is generated by supplying the waste plastic containing a carbon fiber to a cement kiln for treating it by combustion, to a dust collecting apparatus for scavenging dust; the waste plastic containing a carbon fiber is pulverized to have an average particle size of 3 mm or smaller and supplied to a position where the internal temperature of the cement kiln is 1,200°C or higher.
