DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention relates to: conditions, wherein the material is exposed to the vapor of a special mixture; such as polyvinyl chloride , which is extensively used for housing culture, malting culture and the like by farmers, using a mixture solution of methylene chloride and water as a strong oxidative mixture liquid in a treatment equipment; chloride film, as the type of waste synthetic resin film mentioned above; synthetic resin from collected trash bags including domestic garbage or waste films of synthetic resin prior to incineration thereof; vegetation and dissolving water and fat thereof, thereby easing extraction of vegetable essence thereof, or easing a process for reducing the amount of water in the garbage; which is used in a process of producing phosphatic manure of powdered bones comprising a step of removal of fat from bones of cattle or pigs, or a process of producing feed of powdered bones comprising a step of removing fat from bodies of sardine or horse mackerel.
DESCRIPTION OF RELATED ART
Conventionally, a general method of oxidizing material entails heating at a high temperature or soaking in an alkaline or acid solution.
However, it is impossible to use a conventional method for oxidizing material which is spoiled by heating at high temperature or by soaking in solution.
The present invention relates to a method of penetrating vapor or gas into such material, which cannot be heated at high temperature or soaked in a solution, in a processing tank having a low temperature about 50-150.degree. C.
Also, waste synthetic resin film is usually dumped as general garbage and incinerated in a garbage furnace.
However, the synthetic resin film makes up large quantities of the garbage, and is of industrial waste, which is different from general trash or garbage in quality. A large amount of heat is generated when the synthetic resin film is incinerated. Chlorine gas is generated when polyvinyl chloride is burned up. The disposal of synthetic resin film costs too much as a public enterprise because of its acceleration of damage to a trash burner and its smoke pollution.
Therefore, some public bodies require a person who dumps a waste synthetic resin film to pay the expense of disposal thereof.
"PCB" is a general term for polychlorinated biphenyl, which is a mixture of chlorinated biphenyl having two, three, four, five or six chlorines. The PCB is easy to deal with because it is chemically, physically stable and it is liquid at normal temperatures. Although PCB is not used currently because it is harmful, it has ben primarily used as an insulator of a condenser or a transformer or as an ingredient of a pressure sensing paper or so on.
However, there still remains the problem about disposal of goods containing PCB. Detection of PCB from the ground, drainage or sludge constitutes a public problem.
It is extremely hard to resolve and make PCB harmless because PCB is stable.
Under these circumstances, the study for resolving and making PCB harmless is carried on. For example, exposing PCB to ultraviolet rays and culturing microorganisms in the ground containing PCB are known as methods of resolving PCB.
Such technology is disclosed in Japanese Patent Provisional Publication No. 4-370097, for example.
Also, as another method of resolution and disposal of PCB is known a technique to make PCB harmless by putting insulating oil containing PCB into a heating furnace, heating PCB at a temperature less than 110.degree. C. so as to evaporate and separate PCB, and burning the PCB gas and the combustion gas of PCB so as to resolve in another furnace which is at a high temperature of from 1200 to 1500.degree. C.
The technique is shown in the Japanese Patent Provisional Publication No. 2-232073.
Also, conventionally, a method of processing a pig bone or cow bone to remove meat for removal of fat is boiling the bones well. The bones are ground into powder after the process and are used as powdered bone. It is preferred to burn up the bone without processing for removal fat rather than
