Abstract: A process for processing solid residual material that is generated from 1 from solid waste incinerator through a series of crushing and screening processes into homogenous and aggregate material, comprising the steps of (a) feeding the solid residual material to process through a feeder to a sorting unit comprising a plurality of vibration screens of different meshes for sorting the solid residual material into coarse particle size residual material, medium-size residual material, and fine particle size residual material; (b) reclaiming the coarse particle size residual material; (c) using a magnetic separator to remove ferrous metal material and then using a crusher to crush the remaining residual material and then delivering the crushed material to the sorting unit for sorting again; (d) carrying the fine particle size residual material by water through a water channel to a washing unit and keeping the fine particle size residual material in contact with water for about 1 minutes or more so as to let toxic
