Abstract: A waste plastic oilification reduction system includes: a main condensation process unit including a main condensing section that has a main condensation tank to which decomposition gas in a main pyrolysis process unit is supplied and a cooling section that cools the main condensation tank, and is configured to condense the decomposition gas to produce recycled oil; a sub-pyrolysis process unit having a sub-pyrolysis tank to which a residual gas component remaining in the main condensation tank is supplied and a heating section that heats the sub-pyrolysis tank, and being configured to heat the residual gas component to produce re-decomposition gas; and a sub-condensation process unit including a sub-condensing section that has a sub-condensation tank to which the re-decomposition gas produced by the sub-pyrolysis process unit is supplied and a cooling section that cools the sub-condensation tank, and is configured to condense the re-decomposition gas to produce the recycled oil.
