Efforts to reduce food waste in general households and restaurants are being activated, but it is not easy to control the increasing amount of food waste, and landfilling it will not only limit the landfill site, but also cause environmental destruction due to odor and leachate.

For this reason, the government stipulates that a processing device capable of inducing fermentation, drying, or extinction of food waste can be installed in a group meal service area or when building a new apartment building.

Meanwhile, in order to reduce the volume of food waste, an activated carbon adsorption method, a chemical cleaning method, a microbial deodorization method, an ozone oxidation method, and the like are being used as methods for removing odors emitted during crushing and compression.
