Briefly, in the former case, in order to crush and decompose the above-mentioned food waste, a porous ceramic ball and a carrier member are added to increase the microorganism's habitat, and at the same time, stabilize the microorganism's format and buffer the ceramic ball. Prolong the service life of the food, and promote the decomposition of food waste. However, in the former case, the structure is complicated, so the production cost and price of the product are high, and the maintenance is difficult, resulting in inefficient and economic burden, and in the latter case, the food waste is dehydrated and crushed and then decomposed. Although it can be treated, the food waste is not only spent a long time to decompose the food waste by the microorganisms, but also the food waste is released to the outside intact.

In particular, according to the change in diet, food waste contains a large amount of salt or oil components, which is not only difficult to process, but also takes a long time to decompose, and degrades performance as well as a major cause of environmental pollution.
