The purpose of garbage classification is to reduce the amount of garbage disposal, recycle renewable resources, and turn waste into treasure, so as to reduce the problem of garbage pollution. For example, waste paper is sent directly to paper mills to produce recycled paper; Beverage bottles, cans, etc. can also be sent to processing plants to become renewable resources; Waste clothes can be sent to special factories for processing.
Garbage classification leads the new fashion of low-carbon life!
The following is the knowledge of domestic waste classification
Why waste sorting?
Garbage classification is a reform of the traditional way of garbage collection and disposal, and a scientific management method for effective disposal of garbage. In the face of the increasing garbage production and the deterioration of the environmental situation, how to maximize the utilization of garbage resources, reduce the amount of garbage disposal, and improve the quality of the living environment through garbage classification and management is one of the urgent issues that all countries in the world are concerned about.
What are the categories of household waste?
"Four steps" of garbage classification
Step 1: Is it toxic and harmful
Step 2: Is it recyclable
Step 3: Is it perishable, fermented, and smelly
Step 4: The rest is other garbage
Step 1
Hazardous waste: It will cause direct or potential harm to human health or the natural environment, and will be handed over to a professional disposal unit for harmless treatment after being classified and put into place. There is not much common hazardous waste in daily life, remember the mantra: "mercury lamp medicine (mercury, lamp) pool paint (pool, paint)".
Mercury: that is, mercury-containing thermometers, sphygmomanometers, etc.;
Lamp: that is, a lamp, such as a fluorescent tube;
Pool: that is, batteries, in addition to alkaline batteries, lithium batteries, etc., most batteries are generally hazardous waste, which will contain or produce lead, mercury, cadmium and other toxic and harmful heavy metal elements and substances;
Paint: that is, volatile harmful solvents such as paint, such as paint buckets and nail polish;
Step 2
Recyclables: It is suitable for recycling, recyclable domestic waste, although there are many types of recyclables, but there is also a convenient memory formula: "paper-plastic glass gold clothing".
Paper: that is, waste paper, and generally has a certain hardness, such as printing paper, envelopes, and paper towels, wet wipes, paper tableware, no matter whether they have been used or not, there is no recycling value;
Plastic: clean plastic products, such as washed beverage bottles, styrofoam, etc., while disposable plastic tableware or contaminated plastic bags with oily residue after meals have no recycling value;
Glass: that is, "pure" glass products, and mirrors composed of glass and coating are composite products and are not recyclables;
Gold: i.e., metal products;
Clothing: that is, waste fabrics, but excluding towels, underwear, stockings, etc., they have no recycling value due to special use, etc.
Step 3
Kitchen waste: refers to domestic garbage with organic matter as the main component, which has the characteristics of perishable, fermented and smelly. After sorting and putting it in, it will be handed over to a professional disposal unit for "composting", power generation, extraction of substances that can be used for production or harmless treatment, and the vast majority of food is kitchen waste. Just remember that the following are not kitchen waste to be accurately sorted: bamboo products, large bones, hard shells, coconut shells, durian shells, walnut shells, sugarcane husks, corn coats, dumpling leaves, hard fruit pits, etc.
Step 4
Other waste: refers to other domestic wastes other than hazardous waste, recyclables, and kitchen waste, most household hygiene products, and composite ones. Products that are composed of a variety of materials and parts that are difficult to disassemble, such as lighters, pens, umbrellas, etc.
How can we reduce waste?
Garbage classification itself can not reduce garbage, let alone eliminate garbage, to fundamentally reduce the pollution of garbage to the environment, but also must take active action to reduce garbage generation. To do:
The implementation of garbage classification is related to the living environment and physical and mental health of the people, energy conservation, emission reduction and resource reuse, strengthening the health publicity and education of garbage classification, popularizing garbage classification knowledge and laws and regulations to the public, guiding the public to develop awareness of garbage classification, improving public environmental and health literacy, and doing a good job in garbage classification requires the participation and cooperation of each of our citizens.
