Nearly, three-quarters of the steel produced annually are obtained from the integrated route (BF-BOF). It is known that use of coke in BF results in 1700 kg CO2 emission per ton of hot metal. In relation to zero CO2 emission target, many investigations have been conducted in steelmakingSteelmaking industry for many years. One of them in blast furnaceBlast furnace process can be regarded as replacing coke with certain alternatives. In this respect, substitution of coal and coke with biomassBiomass, use of coke oven gas (COG), use of pure H2 gas, and use of waste plasticsWaste plastics are some examples to the efforts to reduce CO2 emissions. In this paper, the studies aiming to substitute coke with waste plasticsWaste plastics are reviewed. © The Minerals, Metals & Materials Society 2025.eninfo:eu-repo/semantics/closedAccessBlast FurnaceCarbon DioxideWaste PlasticsConference ObjectN/AQ497104
