Poly (ethylene terephthalate) (PET) is a versatile plastic and is widely used in the manufacture of products such as food packaging material, water and soft-drink bottles etc. As the consumption of PET increases, waste PET (wPET) is rapidly emerging as a major constituent of urban waste. Amongst the various chemical recycling of wPET, glycolysis shows distinct advantage due to its ability to synthesize value added products. So, in this study, we optimized the reaction conditions of glycolysis using microwave by Taguchi method. In the first step, the catalysts with the highest BHET yields were selected by confirming the effect of catalysts containing Zn, Ti, Fe and Co ions. In the second step, the ratio of PET:EG and catalyst were optimized by Taguchi method. In the third step, the optimization of catalyst ratio, time and temperature was carried out using the Taguchi method. The degree of glycolysis reaction at each step was compared using BHET yield. |
