Taking into account global trends in reducing the impact of anthropogenic factors on nature, namely the utilization of plastic waste and decarbonization of industrial facilities, the article studies the impact of the use of plastic in a blast furnace, as the most energy-intensive unit in the steel production cycle, on the technical and economic indicators of blast furnace melt and CO2 emissions from the blast furnace based on the heat balance. It was found that the use of plastic in a blast furnace will allow solving the issue of its utilization with the least environmental impact. The quantitative impact of plastic use on furnace performance, coke consumption, and CO2 emissions was determined. The coefficient of coke replacement by different types of plastic when used in a blast furnace was determined.
