To provide a waste plastic processing method that can effectively process thermosetting waste plastic using a vertical-type melting furnace.SOLUTION: Provided is a waste plastic processing method in which, when processing thermosetting waste plastic in a vertical-type melting furnace, the waste plastic is first heated, softened, and melted using an extruder to produce a volume-reduced waste plastic, and then the volume-reduced waste plastic is crushed and made into crushed waste plastic. Preferably, the thermosetting waste plastic is processed in the vertical-type melting furnace by blowing the crushed waste plastic into the furnace of the vertical-type melting furnace through the tuyere.SELECTED DRAWING: Figure 1 【課題】竪型溶解炉を用いて熱硬化性の廃プラスチックを有効に処理することができる廃プラスチックの処理方法を提供する。【解決手段】竪型溶解炉で熱硬化性の廃プラスチックを処理するにあたり、廃プラスチックをまず押出成形機を使用して加熱、軟化、溶融させて減容廃プラスチックとし、次に、その減容廃プラスチックを破砕して破砕廃プラスチックとする。好ましくは、破砕廃プラスチックを竪型溶解炉の炉内に羽口から吹込むことにより、熱硬化性の廃プラスチックを竪型溶解炉にて処理する。【選択図】図１
