Abstract
A method for grinding plastic waste includes mixing 30 to 80 wt % of plastic waste and 20 to 70 wt % of a woodchip by a mixer after equalizing the size of a diameter or a side thereof so as to be 5 mm or less, and grinding a mixture thereof into a fine powder with a particle size of 1 mm or less by a grinding device including a rotor rotating at a high speed.
