Modification of plastic wastes from electrical products

We have developed a method of recycling technology to use scrap plastic for cleaning waste water from a semiconductor plant. This is a technology which transforms polystyrene waste from electrical products which contain additives such as coloring materials into water-soluble polymers by sulfonation. These polymers work as a flocculant for the disposal of waste water from factories. A new reclamation technology to modify polystyrene waste is noted and discussed in this report.
