In general, there are methods for treating food waste, such as fermentation, incineration, feed and fertilizer (compost), landfilling, etc. However, the methods described above may require large-scale facilities. In addition, various side effects such as odor or discomfort associated with collection, transportation or storage, and serious social problems such as environmental pollution are caused.

Therefore, there is an urgent need for a method of reducing environmental pollution caused by food waste and recycling the same.

On the other hand, despite the current total number of households exceeded 10 million households, the measures and results for the disposal of food waste related to environmental pollution are still insufficient. The main reason may be housewives' lack of awareness of resources and environmental pollution.

Therefore, in order to efficiently control the generation and recycling of food waste, it is urgently required to develop a household food processor capable of solving such problems.

In general, a device that treats food waste by connecting to a sink in a home is capable of significantly reducing its volume by removing water from food waste through a series of processes such as dehydration, cutting, and drying, and reducing its volume.
