Field of the Invention [0002] The present invention relates to a closed system for treating organic wastes, and more particularly, to a closed system for treating environmentally friendly organic wastes, which can prevent the discharge of harmful substances to the outside from the input of organic wastes to the completion of treatment.

In recent years, there has been a global concern about the problem of wastes in society, and the second pollution occurred during the incineration and landfilling processes of the above-mentioned wastes, and the concern about food waste, livestock manure and sludge .

Most of the above-mentioned food waste is classified as organic waste because it contains a large amount of organic matter decomposable by microorganisms.

A problematic factor in the processing of organic wastes is high moisture content, with food waste being around 80-85%, and sludge being around 75-80%. Such a high moisture content lowers the calorific value at the time of incineration, increasing the amount of auxiliary fuel used and, in some cases, inducing incomplete combustion.

In addition, it becomes an increasing factor of leachate at the landfill stage, and organic matter is rapidly decomposed at a high moisture content, which is a cause of malodor.

Due to the above-mentioned various problems, the regulatory movement of organic wastes has been regulated in recent years and induction of bringing in the water with the maximum moisture suppression has been caused, but it still causes many problems.
