Kitchen waste is a general term for waste food produced by families, hotels, restaurants and restaurants or canteens of government agencies, enterprises and institutions.

Food waste is characterized by high water content, high organic content, high oil content, and high salt content. Its main components include starch in staple food, cellulose and pentosan in vegetables and plant stems and leaves, protein and fat in meat, etc. The content of NaCl in inorganic salt is high, and a small amount of trace elements such as Ca, Mg, Fe, K are also contained. Its chemical composition is mainly C, H, O, PS and Cl.

Food waste is rich in organic matter, high in nutrient content, complete in nutrient types and high in water content. If it is not treated in time, it is easy to rot. Its properties and smell will have a bad impact on environmental health, and it is easy to grow pathogenic microorganisms, mycotoxins and other harmful substances. In terms of the existing form of substances, there are a large number of solid substances and organic substances dissolved or suspended in water in the organic substances in the food waste, of which the solid substances account for more than 30%, which is the main form of organic substances in the food waste.

The company adopts the technology of physical separation and double transformation of insects and microorganisms to conduct harmless treatment and resource utilization of kitchen waste, and the product is "industrial oil+insect protein+biological organic fertilizer (or raw material)". Specifically, firstly, the barrier is used to separate the non degradable solids such as plastic bags and beverage bottles, and then the solid organics are separated from the oil and water through solid-liquid separation; Oil and water are boiled and three-phase centrifuged to obtain oil and sewage, which can be used as biodiesel or aviation fuel; The mechanical vapor recompression (MVR) technology is used to desalt the sewage, and the membrane bio reactor (MBR) is used to reduce COD, ammonia nitrogen, total phosphorus and other pollutant indicators, and then the sewage is discharged into the urban pipe network. After the solid organic matter is fully fermented by adding beneficial bacteria such as Bacillus, Lactobacillus, and Yeast, it is homogenized, inoculated with larvae or maggot eggs, and the protein, sugar, fat and other nutrients in the maggot are recycled through the maggot. The maggot can be directly used to feed aquatic animals (rare fish and shrimps, etc.), or to breed livestock and poultry animals such as chickens, ducks, pigs, and can also be homogenized and used as feed materials for high protein animals; The residues obtained from the rearing of fly maggots can be added with organic auxiliary materials and decomposed bacteria for high-temperature fermentation and drying, and then crushed, added with phosphorus ore powder, potassium feldspar, nitrogen fixation, phosphorus hydrolysis and potassium hydrolysis bacteria groups and plant pathogenic bacteria to prepare high-quality insect manure biological organic fertilizer; It can also be directly used as the raw material of high-quality multifunctional bio organic fertilizer products without adding.
