Garbage classification means that different types of garbage are collected and put separately at the source of garbage production according to certain standards or regulations, which provides convenience for the subsequent garbage treatment and helps to realize garbage reduction and recycling. At present, domestic waste in China is generally divided into kitchen waste, recyclables, harmful waste and other wastes. The nature of garbage has also changed in the process of garbage classification and treatment. Within the scope of private houses, garbage belongs to residents' private goods. Therefore, when these domestic wastes are still at home, we have the responsibility and obligation to collect and put them in a certain category. In the past, domestic garbage was uniformly treated by garbage sorting plants, which caused great waste of resources and consumed a lot of time and manpower. Nowadays, the classification of domestic garbage has become a new fashion trend. While producing garbage, we treat it scientifically, cultivate the consciousness and habit of garbage classification, and practice the concept of environmental protection from time to time in our daily life.

garbage sorting is not difficult, nor will it take too much time and energy. We can put four trash cans in our home, which are blue recyclable trash cans, green kitchen waste trash cans, red harmful trash cans and other gray trash cans. In daily life, we only need to throw different kinds of garbage into the corresponding trash can. When dumping garbage, put different kinds of garbage into the corresponding garbage truck or garbage collection area.

Kitchen waste should be put in special containers separately. In principle, closed containers should be used for storage in other places except open containers in farmers' markets and agricultural products wholesale markets. Kitchen waste can be cleaned by special personnel to avoid mixing with waste tableware, plastics, beverage bottles and cans, waste paper and other impurities that are not conducive to subsequent treatment, and achieve "daily cleaning". In addition, a ledger system should be established according to regulations (except for farmers' markets and agricultural products wholesale markets) to record the types, quantities and destinations of kitchen waste.

The kitchen waste should be transported to professional units by closed special vehicles, and the control of leakage, leaving and odor should be strengthened during transportation. Relevant departments should strengthen the monitoring of the transportation and treatment of kitchen waste.
