<p>PROBLEM TO BE SOLVED: To enhance the resource recovery efficiency of recovering a blast furnace raw material from a waste plastic material sorted from general waste. SOLUTION: A film waste plastic material, a solid waste plastic material and a particulate waste plastic material are sorted from general waste by a shaking sorter and impurities are separated from these waste plastic materials. The particulate waste plastic material is allowed to meet with the film waste plastic material after impurities are separated. The film waste plastic material is crushed, sorted, dried and granulated to be recovered as a blast furnace raw material and the solid waste plastic material is crushed and sorted to be recovered as a blast furnace raw material.</p> |
