Abstract. This study analyzes the application possibilities of solid carbon residues (char) formed as a result of polymer waste pyrolysis as adsorbent materials and coke. The article examines activated carbon production methods, physical-chemical properties, and industrial applications. Research results indicate that it is possible to obtain activated carbon with a specific surface area of 2712 m²/g from pyrolysis char materials using KOH activator. The efficiency of char materials in adsorbing heavy metals ranges from 85-95%. The article provides a comparative analysis of works by international and national researchers and evaluates the prospects for application in coke production. Technological process optimization methods and economic efficiency indicators are also studied.
