PROBLEM TO BE SOLVED: To solve the problem that disposing organic matters (excluding feces and urine), wherein the organic substances means expired disposal food materials, processed food residues, leftovers, decomposing matters, feces, and the like, are mainly processed by incineration treatment which requires huge amount of fuel, these incineration disposals leading to environmental destruction by the generation of CO2, feces and urine and the like being dumped in the ocean and spurred the environmental destruction of the sea, sea farming fishery which has been actively carried out in recent years causing sludge because the leftovers of feeds given to such fishes are deposited, and spoiling water, thereby the environment of the seawater being destroyed.SOLUTION: The maggot lay eggs in a septic matter, a chain from a maggot to a fly so as to lay eggs cycling rapidly, and additionally the maggot having a habit of crawling up. Disposing organic substances and environmental destruction can be inhibited by providing a wall on which a maggot can crawl up easily and a growth space allowing the chain from a maggot to a fly to be advanced so as to exert such abilities, and thereby the above subject can be solved.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,JPO&INPIT【課題】有機物の処理、ここで言う有機物とは期限切れ処分食材、加工食品残渣、残飯、腐敗物、糞便等このような有機物(糞尿を除く)は主にその処理は焼却処理で行われ莫大な燃料を必要とし、これらの焼却処分によりCO2の発生で環境破壊につながる。また糞尿などは海洋投棄されて海の環境破壊に拍車をかけます。近年海面養殖漁が盛んにおこなわれています、これら魚に与えられる餌で、食べ残しが沈殿し汚泥のもととなり水を腐敗させ海水の環境を破壊します。【解決手段】ウジ虫は腐敗物に産卵し、ウジ虫~ハエ~産卵とその連鎖は早い又ウジ虫は這い上がる習性があります。これらの能力を最大限に発揮出来るように這い上がりやすくする壁、ウジ虫~ハエの連鎖を早める生育空間を設けることで、有機物の処理、環境破壊の阻止ができ上記の課題を解決できます。【選択図】図1
