Using polymer waste in coke production

The utilization of solid domestic waste—plastic, rubber, leather, textiles, wood, and paper—in coking batch after mixing with residues from coal-tar stores at coke plants is investigated. All the solid domestic waste considered—especially plastic waste—increase the yield of coke in the >80 and >60 mm class and the yield of tar and benzene. The introduction of plastics and a mixture of solid domestic waste with up to 1% of tar-storage residues does not impair the quality of the coke produced.
