The increasing emphasis on sustainability in the steel industry has prompted investigations into the use of waste polymers as an alternative carbon resource in electric arc furnace (EAF) steelmaking. This study aimed to explore how the composition of blended metallurgical coke and polymers influences carbon/slag interactions at elevated temperatures (1,550°C). Employing a sessile drop arrangement, the interactions of coke with polyethylene terephthalate (PET) and polyurethane (PU) were analyzed. The results showed that CO emissions from both polymer/coke blends were lower than those from traditional metallurgical coke. Additionally, enhanced slag foaming was observed, signified by an increased volume of gas bubbles and improved entrapment of gas within the slag droplet. The PET and PU blends also contributed to a notable increase in H2O formation due to the reduction of FeO by H2, further indicating a complex interaction between these components during EAF processes. These findings suggest that utilizing various waste polymers can not only reduce coke consumption but may also contribute to lower greenhouse gas emissions in EAF steelmaking, representing a significant step towards more sustainable practices in the industry.
