Provided is a method for producing a pulverized waste plastic wherein it is possible to produce at a low cost and with improved productivity a pulverized product by micropulverization of waste plastic. The method for producing a pulverized waste plastic is characterized in that waste plastic is kneaded at a shear speed of 100 (1/second) or greater as it is being melted at a temperature that is the softening and melting temperature or greater, preferably 160°C, but is a temperature at which flammable decomposition gases are not generated, preferably 270°C or lower, and then is cooled and solidified and the solid product is pulverized. Melting and kneading are preferably performed using an extruder, particularly a biaxial extruder. |
