The disposal methods of kitchen waste are as follows:

1. Landfill method

Landfill treatment is a simple and common garbage disposal method. But it will limit the comprehensive recycling of garbage resources, and occupy a lot of land and pollute the environment.

2. Incineration method

Mixing kitchen waste with domestic waste for incineration or establishing a waste incineration plant to generate electricity through the heat generated by waste incineration will cause certain air pollution.

3. Composting method

Relying on microorganisms such as bacteria, actinomycetes and fungi which are widely distributed in nature, under the condition of manual control, the water in catering waste residue is evaporated, dried and ground, and the catering waste residue is transformed into organic compound fertilizer for agricultural production through a series of treatment procedures to prevent harmful gases from being generated. Composting treatment mainly includes aerobic composting and earthworm composting.

4. Anaerobic fermentation

Anaerobic process refers to the production of biogas from garbage, which is converted into electricity and gas, and the residue produced in the anaerobic digestion tank is subjected to secondary fermentation composting. Biogas, hydrogen, ethanol or lactic acid can be obtained by anaerobic digestion of kitchen waste.

5. Production of biodiesel

Biodiesel refers to diesel produced by transesterification with animal and vegetable oils as raw materials, also known as renewable fuel. Waste cooking oil is made into bio-oil by acid and alkali two-step method, separation reaction method and complete catalysis method. With the help of intelligent kitchen waste disposer such as Lvyoubao, the amount of kitchen waste can be reduced at the source, and dry-wet separation, oil-water separation and discharged oil can be recycled as biodiesel raw materials, which is a relatively environmentally friendly treatment method and the future development trend of the kitchen waste treatment industry.
