| Chemical Recycling Of Waste Expanded Polystyrene
Nowadays, rapidly rising plastic wastes and their crucial importance to the environment are the reasons of evaluation of new tecnologies for recycling of these materials. There are mechanical, thermal and chemical recycling methods..
In this study, a chemical recycling method; sulfonation was used. Waste EPS is sulfonated either by using sulfuric acid simply or by sulfuric acid in the presence of AgCl as catalyst. Characterization of sulfonated products was carried out by using FTIR spectroscopy and DSC.
Films were prepared from the products sulfonated with sulfuric acid and their usability as surface coatings were investigated. Drying time, hardness, adhesion, impact resistance, water and acid resistance of films were determined and the results were compared with reference film prepared fromwaste EPS. Also it was investigated whether the products sulfonated by sulfuric acid in the presence of catalyst are used as polyelectrolytes for aiding water treatment processes with coagulation-floculation.
