To effectively prevent ignition phenomenon caused by crushing of an ignitible battery such as a lithium ion battery.SOLUTION: A bulky waste treatment method for treating bulky waste 10 including an ignitible battery 12 is provided that includes: a crushing step of crushing the bulky waste 10 into crushed waste 14; a separation step of receiving the crushed waste 14 crushed in the crushing step, and separating the crushed waste depending on the size of the crushed waste 14; a small-sized crushed waste transportation step of classifying the small-sized crushed waste 16 separated in the separation step and including the ignitible battery 12 from other large-sized crushed waste 18 and transporting the classified small-sized crushed waste 16; a heat detection step of detecting heat generation or firing from the small-sized crushed waste 16 transported in the small-sized crushed waste transportation step; and a fire extinguishing step of extinguishing fire when heat generation or firing from the small-sized crushed waste 16 is detected.SELECTED DRAWING: Figure 1 【課題】リチウムイオン電池のような発火性電池の破砕が原因で引き起こされる発火現象を効果的に防止する。【解決手段】発火性電池１２を含む粗大ごみ１０を処理するための粗大ごみの処理方法であって、前記粗大ごみ１０を破砕し破砕ごみ１４にする破砕工程と、前記破砕工程によって破砕された前記破砕ごみ１４を受け入れ、前記破砕ごみ１４の大きさに応じて選別する選別工程と、前記選別工程によって選別された、前記発火性電池１２を含む小型破砕ごみ１６を他の大型破砕ごみ１８と分けて搬送する小型破砕ごみ搬送工程と、前記小型破砕ごみ搬送工程によって搬送される前記小型破砕ごみ１６からの発熱又は発火を検知する熱検知工程と、前記小型破砕ごみ１６からの発熱又は発火が検知された時に消火する消火工程と、を含む。【選択図】図１
