The way to use food waste as fertilizer is: chop up the food waste, add water to cook a little, let it cool and then loaded into a container that can be sealed, such as beverage bottles, plastic jugs and so on, sealed and placed in a place where they do not get in the way to let the natural fermentation, when you see the liquid in the container has become a blackish-brown can be added to dilute the flowers, the use of concentration control in 5% or so. In addition, there are vermicomposting method, woven bag composting method, aeration composting method, Pocahontas composting method and other methods to deal with food waste.

Vermicomposting (vermicomposting/worm composting) is the process by which earthworms convert organic wastes such as food into nutrient-rich soil. The earthworms inhale the decaying food scraps and excrete the fertilizer - a great improvement in soil quality.

Aerated composting evolved from traditional open composting and is one of the aerobic composting methods. Under incompletely closed conditions, food waste is decomposed into fertilizer and turned into fertile soil through the action of aerobic microorganisms. In this composting method, air permeability is very critical, because aerobic bacteria need to have enough oxygen supply to survive, and they can only effectively play their value when they multiply under such conditions.

Extended information:

Food waste contains very high moisture and organic matter, which can easily decay and produce a foul odor. After proper handling and processing, it can be transformed into a new resource. The high organic matter content makes it possible to use it as fertilizer and feed after rigorous treatment, as well as to produce biogas for use as a fuel or for power generation, and the oil and grease portion of the waste can be used for the preparation of biofuels.

Food waste is rich in a large amount of organic matter and nitrogen, phosphorus, potassium, calcium and a variety of trace elements, into organic fertilizers used, not only to maintain a stable food production, increase production, promote resource recycling, to solve the environmental problems caused by improper treatment of food waste, but also reduce the input of external inorganic fertilizers to save investment, protect the environment, on the soil, food safety and human health are very beneficial.
