SUMMARY:Usability of plastic wastes in metallurgical coke process
DESCRIPTION:Keywords:  Plastic Waste, Cokemaking, Metallurgical Coke, Coke Production 
Coke is one of the main input raw materials of iron and steel production. Especially in blast furnaces, it is used as a heat source, reducing agent and burden supporter. In recent years, due to carbon emissions and environmental regulations, iron and steel factories are working on this subject. In this context, various studies are also carried out in cokemaking process, the use of plastic wastes in coke ovens is one of these studies. Plastic wastes can be used in coke ovens as a substitute for coal by adding certain proportions to the coal blend after several pretreatments.
In this study, polyolefin-based HDPE (high density polyethylene) and polyaromatic-based PS (polystyrene) were added to the coal blend at 1% after briquetting with coal. The total briquetted coal ratio in the coal blend was set as 10%. Subsequently, the coking process was carried out in a laboratory scale coke oven with a capacity of 5 kg. Results showed that, with the addition of plastic waste to the coal blend, the reactivity and strength values of coke were not adversely affected, chemical and ash analyzes were found suitable for blast furnaces. However, the change in the amount of by-products in the coke process with the addition of plastic to the coal blend was investigated. It has been observed that each waste plastic has a different effect on coke by-products.
