れている。(B) Conventional technology In the past, kitchen waste such as leftover food discharged from food establishments such as restaurants, hotels, cafeterias, hospitals, and school lunches in cities has originally been used as livestock feed. Only a small part is used in pig farms in the suburbs, and most are disposed of by incineration or sewage treatment.
（ハ） 発明が解決しようとする問題点 このように上記廃棄物は飼料として利用されているのは
ごく一部であり、さらに最近では、悪臭公害や、調理給
飼上の取扱いの問題、軟脂豚の発生等によって利用する
養豚場が少なくなる傾向にある。(C) Problems to be Solved by the Invention As described above, the above wastes are used as feed only in a small part, and more recently, there are problems such as bad odor pollution, handling problems in cooking and feeding, and softening. The number of pig farms to be used tends to decrease due to the generation of fat pigs.

どの難点があり実用には至らなかった。As a method for processing kitchen waste, an attempt was made to dry by a direct heating method using a heat source such as steam, but there are drawbacks such as deterioration of quality such as rapid oxidation of fat and consumption of a large amount of fuel. However, there was no practical use.

ある。(D) Means for Solving Problems In the present invention, the freshness of waste such as leftover rice produced from the kitchen is judged, and the one with good freshness is used as the waste for oil temperature dehydration treatment, and The waste for oil temperature dehydration treatment is
Under a two-stage depressurization condition of light decompression at the beginning and strong decompression at the end, the waste is dehydrated and dried to be used as livestock feed and discarded for methane fermentation. Methane fermentation process is performed under anaerobic conditions, the generated methane gas is used as an energy source for oil temperature dehydration process, etc., and digested sludge is dehydrated and converted into compost. It is intended to provide a treatment method.

ものである。(E) Action / Effect According to the present invention, the quality of the feed raw material is maintained by sorting the kitchen waste to make the one with good freshness into the waste for oil temperature dehydration treatment as the feed raw material. However, by performing an oil temperature dehydration process using heating oil as a heating medium under two-step depressurization conditions, it is possible to produce feedstuff that is of high quality and can be stored for a long time by dehydrating and drying the raw materials, while producing kitchen waste with poor freshness. By using the methane gas obtained by methane fermentation as an energy source for the oil temperature dehydration treatment and the like, energy supply from other sources is unnecessary, and further, by digesting digested sludge of methane fermentation and composting it, The kitchen waste can be fully used as a resource, and
This has the effect of not requiring energy supply from others.
