In daily life, "garbage" is everywhere. You can often find garbage cans in family apartments, garbage cans in streets and lanes, and garbage dumps in suburban areas. There are usually multiple classifications for garbage disposal. So why should garbage be classified? Do you know how to classify?
Garbage classification is a scientific management method for effective disposal of garbage. Through classified delivery and collection, useful materials such as paper, plastic, rubber, glass, bottles, cans, metal and waste household appliances are separated from the garbage and put separately to recycle, reuse and turn waste into treasure.
According to the Implementation Plan of Domestic Waste Classification System, waste can be divided into three categories. The first category is hazardous waste, including waste batteries (cadmium nickel batteries, mercury oxide batteries, lead batteries, etc.), waste fluorescent tubes (fluorescent tubes, energy-saving lamps, etc.), waste thermometers, waste sphygmomanometers, waste drugs and their packaging materials, waste paint, solvents and their packaging materials, waste pesticides, disinfectants and their packaging materials, waste film and waste photographic paper, etc.
We must treat these wastes with caution. For example, the discarded fluorescent tube bulbs should be packaged and fixed when they are put in, to prevent the harmful mercury vapor from volatilizing to the environment due to the damage of the tube bulbs. For example, secondary batteries (commonly known as rechargeable batteries, including nickel cadmium, nickel hydrogen, lithium batteries and lead acid batteries) and button batteries containing hazardous substances such as heavy metals should not be discarded at will, but should be put into hazardous trash cans.
The second category is perishable waste, including kitchen waste from canteens, hotels and restaurants, vegetable and fruit waste, rotten meat, broken meat and bones, egg shells, and viscera of livestock and poultry products from agricultural markets and wholesale markets. Perishable garbage is rich in water, easy to rot and deteriorate, and emits odor. It not only affects the surrounding environment, but also is easy to cause sewage leakage during garbage collection and transportation. Therefore, the perishable garbage should be drained, put into a special garbage bag, and tighten the bag mouth. Perishable trash cans should be covered to avoid polluting the surrounding environment.
The third category is recyclable waste, including waste paper, waste plastic, waste metal, waste packaging, waste textiles, waste electrical and electronic products, waste glass, waste paper plastic aluminum composite packaging, etc. The following four points can be followed when dealing with such garbage:
1. Papers should be stacked as neatly as possible to avoid kneading. Paperboards should also be disassembled and stacked. 2. The products in the containers shall be used up or emptied as much as possible, and shall be put after being cleaned. 3. Glass articles shall be handled with care to avoid cuts and damages. They shall be put into bags or containers after being packed. 4. Fabrics shall be packed neatly and put into designated collection points regularly.
