Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a new technology overcoming disadvantages of the conventional methods used in producing high density plastic particles from waste plastics and carbonizing them in a coke oven. SOLUTION: The method for obtaining fuel gas, liquefaction products and cokes includes: blending ≤5 mass% of the plastic particles having no holes or cracks passing through from the surface to the inside, a bulk density of 0.85-1.1 g/cm3and a volume of 6,000-200,000 mm3, based on 100 mass% of coal; and then carbonizing in a coke oven.
