Formed Coke from Coal and Plastic: A Review

The industrial sector has seen a surge in demand for formed coke due to the steelmaking industry's requirements and increased environmental considerations. Conventional coke's environmental impact and limited availability have prompted industries to seek alternative options. Moreover, plastic waste has become a pressing issue, posing health and ecosystem risks that require immediate attention. Formed coke, made from coal and plastics, offers potential benefits such as reduced carbon emissions and waste utilization. It proves to be a more efficient recycling method compared to incinerating municipal solid waste, as it avoids the release of toxic gases. Incorporating plastics into formed coke production improves energy efficiency and reduces carbon footprints. This review critically examines recent literature on formed coke production using various coal and plastic feedstocks, analyzing accessibility and material properties. The aim is to enhance understanding of coal and plastic utilization in formed coke production for sustainable practices in the steel industry.
