<p>PROBLEM TO BE SOLVED: To provide a method for controlling agglomeration of a thermally decomposed residue which occurs in the process of obtaining an oil by thermally decomposing waste plastics, enabling the discharge of the residue by a vacuum suction method and facilitating and reducing the time of maintenance of a thermal decomposition unit. SOLUTION: This method prevents the formation of agglomerated residue by thermally decomposing the waste plastic in the presence of either one of a fibrous inorganic substance, a bar type inorganic substance, and a resin including a glass fiber.</p> |
