る。(Effects of the Invention) As described above, according to the method for solidifying Styrofoam waste of the present invention, Styrofoam waste is crushed and compressed while being fed by the screw device and the rotating compressor, and generates friction while self-heating. It absorbs heat and melts, becomes semi-molten due to the cooling effect of water, and is continuously formed into rod-shaped solids from a perforated plate. Therefore, the volume of Styrofoam waste can be significantly reduced to about 1/40 to 1/100, and the handling efficiency, transportation efficiency, and landfill efficiency can be greatly improved. In addition, it contributes to the recovery of polystyrene resources as a recycled raw material, and can also be reused as a solid fuel, which is of great benefit in terms of environmental conservation and industrial economy.
