Description
Claims (2)
- 有機廃棄物を発酵して有機肥料を製造する方法であって、
当該方法は、含水率が40〜90質量%の有機廃棄物を前処理する工程と、前処理された有機廃棄物を発酵する工程とを含み、
前処理前の有機廃棄物は、汚泥、生ゴミ、及び、動物又は人間の***物からなる群より選ばれる少なくとも1種以上の有機物であり、
前処理工程は、20〜180分間にわたって、含水率が40〜90質量%の有機廃棄物を15〜40気圧かつ200〜250℃の高温高圧下で撹拌して、その後急激に減圧する工程であり、前処理工程は耐圧容器の中で行われるものであって、減圧する際には、耐圧容器に設けられた複数の圧力解放弁を同時に開放することによって、急激に減圧するものであり、
有機廃棄物を発酵する工程は、前処理した有機廃棄物に対して、前処理を経ない含水率が40〜90質量%の有機廃棄物を配合して有機廃棄物の含水率を調節した後、前処理した有機廃棄物と前処理を経ない含水率が40〜90質量%の有機廃棄物との混合物を堆積して、有機廃棄物内部の温度が55〜85℃となり、水分率が40〜75質量%となるように、温度と含水率とを管理しながら好気条件下で固体培養する工程である有機肥料の製造方法。 - 有機廃棄物を発酵する工程は、前処理した有機廃棄物と前処理を経ない含水率40〜90質量%の有機廃棄物とに対して、さらに木質廃材を配合して、有機廃棄物の含水率を調節する工程である請求項1に記載の有機肥料の製造方法。
