The main purpose of this investigation is to achieve the dechlorination and cracking of PVC producing a low chlorinated oil using a single step process; finding and using a suitable adsorbent that captures the chlorine released in the decomposition of the Poly Vinyl Chloride in the solid phase; then use the adsorbent to enhance red mud chlorine absorption activity. Find an alternative viable use for the waste PVC and red mud that will reduce landfilling. Calcium Hydroxide was selected as the main chlorine adsorbent since it captured 75% chlorine in the solid phase. The calcium hydroxide was mixed with red mud (50/50 wt/wt), and pyrolyzed at 400 °C in a N2 environment for 60 min in a fixed bed reactor using PVC to catalyst ratio of 1:1. The oil had less than 10 ppm chlorinated products and had a higher heating value of 40.78 MJ/kg
