Waste cooking oil is kitchen waste, and kitchen waste is wet waste, so waste cooking oil belongs to wet waste. Kitchen waste is food waste and peels produced in the kitchen, mainly including leftovers, western cakes and other food residues, vegetable stems and leaves, animal bones and viscera, tea residue, fruit residues, fallen leaves of plants such as fruit shells, melons and skins, bonsai, and waste cooking oil.

Wet garbage is garbage generated in daily life and activities such as food processing, catering service and unit catering, which generally includes leftovers, leftovers, peels, eggshells, bones, animal viscera, fish scales, leaves, weeds, etc. Its main sources are family kitchens, restaurants, restaurants, canteens, markets and other industries related to food processing. These garbage should be treated in time to avoid bringing harm to people's lives.

At present, garbage is divided into four categories, namely "recyclables", "harmful waste", "wet garbage" and "dry garbage". When throwing garbage, it should be classified according to these four categories, so that garbage can be better treated and recycled.

In daily life or business activities, the disposal of waste edible oil is a big problem. Many people treat the used oil directly into the sewer, which is actually wrong. Oil is lighter than water, and it will solidify at a slightly lower temperature, which will easily block the sewer pipe and affect the drainage system of the city. Therefore, the sewers near restaurants are easy to block the reverse water.

so what should be done with the used or expired cooking oil?

according to the regulations, the activities of restaurants such as hotels, restaurants and canteens of enterprises (institutions) belong to the activities of providing services for daily life, and the kitchen waste generated by them, including waste edible oil, belongs to the category of domestic waste. Therefore, the waste cooking oil produced by ordinary families and catering industries belongs to kitchen waste and should be put into the kitchen waste (wet waste) bucket, while the plastic bucket can be recycled after cleaning, and the plastic bucket containing cooking oil should be put into the recyclable bucket after cleaning.
