Abstract

Economic growth and changing lifestyle patterns are resulting in rapid increase in generation of waste plastics in the world. Effective disposal of waste plastic is an area being seriously explored as a part of environmental initiatives. An attempt is made to assess the impact of waste plastics in coal blend on the coke properties at pilot scale studies. The present study explores addition of up waste plastic in the coal blend. Experimental trials were conducted in a 120kg pilot-scale coke oven. The coal maximum fluidity at 1% plastic addition was found to be in line with the base composition. Results show that up to 1% plastics can be effectively recycled in the coal blend without any detrimental effect on coke quality. Addition of higher percentages of plastics resulted in deterioration in coke properties e.g. Coke Strength after Reaction (CSR) and Coke Reactivity Index (CRI) and coke yield. The waste plastic utilisation at coke ovens aims at a cleaner and greener environment around us. Based on the lab-scale results, plastic shredding system was installed at JSW Steel Ltd., Vijayanagar Works. During the period Jan’21 to May’22, ~135 tonnes of waste plastic has been consumed in Coke Oven-3. The addition of waste plastics to coal blend in coke making can be attributed as one of the effective ways of waste plastic recycling.
