Abstract: (과제) 
유기성 폐기물로부터 메테인 가스를 발생시키는 장치의 제공. 
(해결 수단) 
폐기물을 투입하는 폐기물 투입조(2), 메테인 가스가 발생하는 발효조(1), 이 메테인 가스를 사용하여 가동하는 발전기(3), 이 발전기(3)가 가동할 때의 폐열을 사용하여 가열된 온수(15)를 순환시켜 순환로(11)를 흐르는 유기성 폐기액(9)을 소정의 온도로 가열하는 가열기(4)를 가지고, 이 발효조(1)의 하단부에 설치한 유출구(10)로부터 흐르고 발효조 내의 유기성 폐기액(9)의 액면(12)보다 상방에 유입구(17)를 가지는 순환로(11)를 설치하고 있다.
