1. What kind of garbage are disposable lunch boxes, chopsticks and paper cups? Are they different types of waste?
Disposable lunch boxes belong to dry garbage, most of which are made of plastic, which is what we often call white pollution.
Disposable chopsticks are dry garbage. Disposable chopsticks use a lot of bamboo and wood. They have to be fumigated with sulfur and soaked in hydrogen peroxide. After one use, they cannot be recycled.
If the disposable paper cups are not cleaned, they should be classified as dry garbage. For example, disposable paper cups with tea leaves. After drinking, the tea residues and liquid residues in the cups should be discarded and placed in the recyclable trash can. If you just drink water, you can directly classify it as recyclable waste.
Garbage can be divided into recyclable and non-recyclable garbage, and non-recyclable garbage is divided into hazardous garbage and organic garbage.
Recyclable garbage refers to garbage that has usable value, such as plastic products, plastic cans, metal, waste paper, glass bottles, cloth, etc.
Hazardous waste belongs to non-recyclable waste, which has no use value and is harmful to human body. Hazardous waste includes batteries, light bulbs, expired medicines, etc.
Organic waste is also non-recyclable waste, which has no use value, but is harmless to the human body, such as kitchen waste such as leftovers, fruit peels, and rotten vegetable leaves.
2, What is the difference between disposable lunch boxes and plastic bags? Whether the two kinds of garbage are recyclable garbage or not...
1. Disposable lunch boxes and plastic bags are recyclable garbage
According to the industry standard of "Classification and Evaluation of Municipal Solid Waste" and with reference to the German Garbage Classification Law, recyclables refer to wastes suitable for recycling, recycling and resource utilization. Mainly include paper, plastic, metal, glass, textile.
Plastics mainly include: waste container plastics, packaging plastics and other plastic products. Such as various plastic bags, plastic bottles, foam plastic, disposable plastic lunch boxes and tableware, hard plastics, etc.
Second, the main difference between disposable lunch boxes and plastic bags
(1) The main components are different
(1) Disposable lunch box
Main ingredients: plastic, paper, starch, rare metals.
(2), plastic bags
Main components: polypropylene, polyester, nylon, etc.
(2), different characteristics
(1) Disposable lunch box
Disposable fast food boxes have been transformed from foam lunch boxes to environmentally friendly lunch boxes. The original foam lunch boxes were eliminated because they were not resistant to high temperatures and caused damage to the environment during the production process. Plastic lunch boxes, paper lunch boxes, wooden lunch boxes, and degradable lunch boxes were replaced. etc. Among them, plastic has the characteristics of low toxicity, high melting point, strong plasticity, easy production and relatively low cost, so it has become the mainstream material for manufacturing disposable snack boxes.
①, polyethylene film (non-toxic)
The film is milky white and translucent (it is especially obvious when several layers are stacked), it is smooth to the touch, as if there is a wax layer on the surface, shaking with force, the sound is brittle, flammable in case of fire, the flame is yellow, and there is sticky dripping when burning , and the smell of burning candles.
②, polyvinyl chloride film (generally toxic)
If no pigment is added, it is transparent, the surface is sticky to the touch, shakes vigorously, the sound is low, and it is not easy to burn in case of fire.
(1) Disposable lunch box
Disposable expanded plastic lunch boxes are also known as disposable expanded polystyrene snack boxes. Among them, polystyrene is used as raw material. If the free monomer styrene in its products is released by heat and enters the human body with food, it will have certain harm to the central nervous system, kidneys, and liver, and even cause cancer. Therefore, long-term use will increase the risk of illness. .
(2), plastic bags
The recycling value of plastic bags is low, and in addition to causing visual pollution in urban streets, tourist areas, water bodies, and both sides of roads and railways, there are potential hazards during use. The plastic structure is stable, not easy to be degraded by natural microorganisms, and will not be separated for a long time in the natural environment. This means that if the waste plastic waste is not recycled, it will become pollutants in the environment and accumulate for a long time, which will cause great harm to the environment.

3. What kind of waste is disposable tableware?
It is dry garbage.
Dry garbage is other garbage, which refers to other domestic wastes other than recyclables, hazardous garbage, and kitchen waste (wet garbage).
The specific classification standards of domestic waste can be adjusted according to the level of economic and social development, the characteristics of domestic waste and the needs of disposal and utilization.
Other wastes are less harmful, but have no reuse value, such as construction waste, domestic waste, etc., generally landfill, incineration, sanitary decomposition and other methods, and some can also be solved by biological solutions, such as earthworms. It is a kind of garbage left over from recyclable garbage, kitchen waste and hazardous garbage.
Classification principle:
1. Divide and use it
The purpose of classification is to divert the waste for treatment, use the existing manufacturing capacity, recycle the recyclables, including material utilization and energy utilization, and landfill to dispose of useless garbage that is temporarily unavailable.
2. Adjust measures to local conditions
The geography of each district, each district, each community (district), each community, the level of economic development, the ability of enterprises to recycle waste, the source of residents, living habits, economic and psychological affordability, etc. vary.
3. Self-governance
Communities and residents, including enterprises and institutions, have gradually developed a code of conduct of "reduction, recycling, self-consciousness, and autonomy", innovated the waste classification and treatment model, and become the main force in waste reduction, classification, recycling and utilization.

5. What kind of garbage do plastic products belong to?
Plastic bags are dry garbage.
Wet waste is perishable waste, usually kitchen waste. The plastic bag is not easy to rot, not easy to degrade, it is dry garbage. That is to say, white pollution, so my country has been advocating that plastic bags should not be used, and cloth bags should be used more. When throwing garbage, you should break the garbage bag, put the wet garbage inside into the wet garbage bin, and then put the plastic bag into the dry garbage bin.
Disposable plastic bags are made of polyethylene and polyvinyl chloride as raw materials, some of which also contain environmental hormones such as plasticizers and phthalates. Phthalates have serious effects on human reproductive health and immune function. Moreover, there are residues or pollutants on waste plastic bags that are difficult to remove, and those containing excessive bacteria or carcinogens are not recyclable.
Garbage classification:
1. Beverage bottles: mainly plastic bottles such as common mineral water bottles, juice beverage bottles, milk tea beverage bottles, etc.
2. Waste paper: writing paper, packaging paper and other paper products that are not seriously stained, including newspapers, periodicals, books, various packaging papers, office paper, advertising paper, cartons, etc. Paper towels and toilet paper cannot be recycled because they are too water-soluble.
3. Metal: Various types of scrap metal items, including cans, tin cans, etc.
4. Textiles: old textile clothes and textile products, including discarded clothes, bed sheets, curtains, tablecloths, towels, school bags, cloth shoes, etc.
5. Plastics: waste container plastics, packaging plastics and other plastic products, including various plastic bags, plastic packaging, disposable plastic lunch boxes and tableware, toothbrushes, cups, mineral water bottles, toothpaste skins, etc.
