NOVELTY - Halogen-containing waste material is processed using cement manufacturing equipment containing preheater (2), and cement kiln (1). The halogen-containing waste material is supplied to classifying apparatus (5) to obtain waste material having high chlorine content and waste material with low chlorine content. The waste material having high chlorine content is introduced into halogen separation unit (8). Then, residue which contacts with cement raw material and combustible gas are extracted from cement kiln, followed by recovering halogen from halogen separation unit.    USE - Processing of halogen-containing waste material e.g. chlorine-containing plastic (claimed) used as drink container, recording tape and tire for motor vehicle.    ADVANTAGE - The method efficiently enables processing of halogen-containing waste material, and provides combustible gas which is used as fuel in manufacturing equipment.    DETAILED DESCRIPTION - Halogen-containing waste material is processed using cement manufacturing equipment containing preheater which preheats cement raw material, and cement kiln which bakes the cement raw material introduced from preheater. The halogen-containing waste material including chlorine, is supplied to classifying apparatus to obtain waste material having high chlorine content and waste material with low chlorine content. The waste material having high chlorine content is introduced into halogen separation unit. Then, residue which directly contacts with high-temperature cement raw material heated at 250 degrees C, and combustible gas are extracted from upstream of cement kiln, and halogen is recovered from gas discharged from halogen separation unit. The obtained combustible gas is supplied as fuel for cement manufacturing equipment. Thus, processing of halogen-containing waste material is carried out.
