Polyvinyl chloride (PVC) powder was ground with NaOH pellets in air by using a planetary ball mill to cause mechanochemical (MC) dechlorination reaction and the product was subjected to thermogravimetric analysis to investigate its thermal decomposition performance. The dehydrochlorination and thermal decomposition temperatures of the product were lowered by the mechanochemical (MC) treatment.The total electric power consumption (EPC) for the dechlorination and thermal decomposition of product was obtained by summing up the values of EPC for the MC dechlorination reaction and thermal decomposition. The total EPC was reduced by the MC treatment and the MC treatment of PVC sample with NaOH lowered the EPC for the thermal decomposition. The effective MC treatment conditions which minimizes the EPC for the sample mixture in the present work are 12 hours grinding at 600rpm with Na/Cl=1 using a planetary ball mill.
