The invention relates to the production of regeneration grainy blakes from thermo-plastic plastics waste materials. Firstly, select the plastics waste according to its different varieties then cut it into small slices and fluff them into individual slices in a fluffer, select by wind for removing impurities, then melt and condense them with sand as medium in melt-condensation machinese so as to make the material into grainy blakes. Secondly, process through acid-immersion, neutrolization, washing, drying up and packing. The regenerated grainy blakes made by this invention are low in degree of aging, applicable to production of industrial and agricutural membranes, and can be made into beautiful colour daily-use articles or construction materials of high grade.
