METHOD FOR PRODUCING CHEMICAL MATERIAL

The present invention relates to a method for producing a chemical product, comprising: a thermal cracking step for obtaining a first gas component, a thermally cracked oil, and a residue component by thermal cracking of a crushed material of a waste material including a waste tire; a hydrocracking step for obtaining a second gas component, a light component having a boiling point of 350 DEG C or less, and a heavy component having a boiling point of more than 350 DEG C by hydrocracking a starting material oil containing at least a portion of the thermally cracked oil; and a steam cracking step for obtaining a chemical product by steam cracking of a steam cracking raw oil containing at least a portion of the light component, the amount of the thermally cracked oil being 45 mass% or more with respect to the total amount of the first gas component, the thermally cracked oil, and the residue component in the thermal cracking step, and the amount of the hydrocracking oil being 45 mass% or more with respect to the
