Sumary: One of the ways of polymer waste management is its chemical modification. Waste polystyrene foam (EPS) and virgin polystyrene (VPS) as reference material were converted into polymeric flocculants by chemical reactions. One of the most popular and widely used procedures to follow the flocculation kinetics is the monitoring of the turbidity as a function of the polyelectrolyte dosage. The application of the obtained products caused a significant decrease of turbidity of the studied solutions. The products were successfully used as flocculants in the treatment of waste water. A colloid system composed of ferrum(III) hydroxide formed the discharge model.
