Method For Producing Recycled Product Of Waste Plastic

Abstract: Provided is a method for producing a recycled product of a waste plastic, whereby it becomes possible to recycle a large amount of waste plastics. The method for producing a recycled product of a waste plastic comprises: charging the waste plastic in a coke furnace at a predetermined maximum charging height that is a height more than half of the furnace width of the coke furnace; performing dry distillation for a predetermined dry distillation time to produce a dry distilled product, tar, light oil, and a gas; and removing the dry distilled product from the coke furnace using an extruder. In the method, the value of the predetermined dry distillation time is obtained by determining a relational expression between a maximum charging height for the waste plastic and a dry distillation time required for the completion of the dry distillation and then calculating the predetermined dry distillation time by substituting the predetermined maximum charging height into the relational expression.
