Plastic bags can be recycled, in addition to the garbage also includes waste paper, waste fabrics, scrap metal and waste glass products, etc., three-dimensional packaging needs to be emptied and flattened before being put in, reasonable delivery to ensure the smooth flow of the channel.
Plastic bags are the best garbage.
Plastic bags belong to the best garbage, the production of plastic bags is difficult, harmful, costly, can be recycled in the later stage, if it is discarded at will will cause great harm to the environment, it needs to be reasonably put into use.
** Refers to renewable and recycled garbage, such as waste plastics, waste paper, waste fabrics, scrap metals and waste glass products, etc., for three-dimensional packaging, the contents need to be emptied and flattened before being put in.
Waste plastics mainly refer to all kinds of hard plastics, foam plastics, disposable plastic lunch boxes and tableware and waste plastics, while metals mainly include aluminum toothpaste, iron cans, iron products, and glass, which refers to two kinds of waste glass products: colored and colorless.

There are more and more plastic bags at home, and you don't know how to deal with them? This method teaches you to repurpose it.
-
Establish an awareness of environmental protection, do not discard the plastic bags generated in daily life, and use those that can be recycled. Intact plastic bags can be used as garbage bags. In this way, you can save the consumption of garbage bags, after all, many people have to buy garbage bags separately; The second is to achieve waste reuse.
Clean and intact plastic bags, which can be organized, folded, and placed in the locker, give priority to used plastic bags when the bags need to be used, recycle, and reduce the production of new plastic bags. Damaged and dirty plastic bags are not recommended to be used again, and should be put into the trash can correctly in accordance with the requirements of garbage classification.

1.When the garbage bag makes.
Anyway, I don't recommend incineration, because the gas from burning is harmful to the human body.
-
1. When garbage bags are used 2, sold as waste 3, when packaging bags are relatively backward due to China's current chemical waste disposal technology, there is no reasonable way, like China's current mainly incineration or landfill.

1. Recycled plastics.
After the waste plastic is manually screened and sorted, it also needs to go through the process of crushing, granulation, modification and other processes to become various transparent and opaque plastic particles, and then classified according to the quality, and finally become recycled plastic that can be reused.
2. Fuel. Waste plastics are used in blast furnace injection instead of coal, oil and coke, in cement rotary kilns instead of coal to burn cement, and in waste solid fuel (RDF) for power generation.
3. Power generation. Waste-to-solid fuel power generation was first applied in the United States, and there are 37 RDF power stations, accounting for the proportion of waste-to-energy power stations. Japan has realized the huge potential of waste plastic for power generation.
Japan has changed some small waste incineration stations to RDF production stations in combination with overhaul, so as to carry out continuous and efficient large-scale power generation after concentration, so that the steam parameters of waste-to-energy power stations have increased from 30012 to about 45012, and the power generation efficiency has increased from the original 15% to 20%-25%.
4. Oiling. Since plastic is a product of petrochemical industry, from the perspective of chemical structure, plastic is a high molecular weight hydrocarbon, while gasoline and diesel are low molecular weight hydrocarbons. Therefore, it is entirely possible to convert waste plastic into fuel...
5. Architectural applications.
The use of waste plastics and fly ash to manufacture building tiles on the cleaning requirements of waste plastics is not very strict, all kinds of waste plastics are different degrees of dirt, generally must be cleaned, otherwise it will affect product quality, is conducive to the actual operation in industrial applications, adding appropriate fillers to the plastic can reduce costs, reduce molding shrinkage, improve strength and hardness, improve heat resistance and dimensional stability.
From the economic and environmental point of view, the choice of fly ash, graphite and calcium carbonate as fillers is a better choice, the surface area of pulverized coal is very large, and the plastic has a good binding force with it, which can ensure that the tile has high strength and long service life.
6. Synthesis of new materials.
This synthetic material is mixed with asphalt in proportion and can be used to pave roads. Increase the hardness of the pavement. Reducing the appearance of crushing marks, it can also be made into thermal insulation materials and widely used in buildings.
According to reports, scientists use the new technology to process plastic waste into a new type of synthetic materials, experts believe that because the technology is plastic waste into new industrial raw materials, not only in environmental protection significance, but also to reduce the use of oil, natural gas and other primary energy, to achieve the effect of energy conservation.

1. Mechanical recycling.
Mechanically recycled e-waste plastics are suitable for large-scale recycling, with a stable source and a collection point close to dismantling manufacturers, material processing and potential product users.
2. As a chemical raw material.
Plastics as chemical raw materials, including the use of mixed plastics as reducing agents in metal smelting processes, are suitable for the following situations:
There are fewer plastics and a wide variety of resins.
Difficulty in product classification and disassembly.
Plastics dealers, dealers and end-users are far away from each other, and the transportation costs of cross-regional recycling of plastics exceed the potential economic benefits of plastics.
3. It is processed as engineering fuel.
Processing plastics into engineering fuels is a small percentage, but it is commercially viable. This approach is highly dependent on close cooperation between the fuel manufacturer and the end user. The economic aspect depends on the fuel manufacturer's manufacturing costs, transportation costs, the selling price of substitute oil or other oils, and the cost of incineration.
4. Energy**.
Energy is defined as follows: the use of daily used plastic boxes without waste plastic products in the consuming country or as an accelerant for other fuels, through the use of resources that generate and heat energy. The main examples are the incineration of household waste to obtain steam, electricity and hot water;Other examples are the high calorific value components of refuse-derived fuels in cement kilns and coal-fired power plants as fossil fuel substitutes, for coal gasification, slag melting, and in metal** systems.
-
**When using waste plastics, sorting is difficult and not economically viable.
The vast majority of plastic waste cannot be degraded or recycled.
Ring utilization, people will fill it in the depths of the garbage dump with other garbage, or burn it on the spot, allowing toxic gases to be emitted and released.
Waste plastics will not only occupy a large amount of land with landfills, but also the occupied land will not be restored for a long time, affecting the sustainable use of land. If waste plastic products that enter household waste are landfilled, it will take 200 years for them to degrade.

I am a polymer learner, and BAI plastic materials can be divided into two categories: thermoplastic plastics and thermosetting plastic inner materials according to their different processing properties. The difference between thermosetting and thermoplastic is like that of ceramics and glass, one can not be melted after heating, and the other can be melted after heating, this characteristic makes thermoplastics can be simply reused, and recycled plastics are mainly thermoplastics, such as PVC, PMMA, PS, PA, PE, PP, ABS, POM, PC, PPO, PPS, etc.
The plastic bag itself can be reused, and many supermarket shopping bags are printed with a logo that can be used! **The difficulty of utilization is mainly due to factors such as economic benefits, and the utilization rate is low, and the merchant can be said to be unprofitable.
Most of the plastic bags you can see on the market today are non-degradable thermoplastics (degradable ones will not be reused!). ), can be reused. However, at present, the classification of domestic garbage is not clear (it is far from enough to use it and cannot be classified), low efficiency (plastic bag raw materials are cheap and easy to obtain, and the cost of recycling is high) and other factors make it difficult to regenerate, and most of them are mixed with domestic garbage to landfill or incinerate things.

I** plastic bag, one yuan a pound. If you have old or unused plastic bags, take them and exchange them for money.
-
Plus what they say! Didn't you hear that there is a technology that can decompose plastic and then make it into gas oil? Check it out when you have time!
-
Put it away and sell it to the scrap collectors, or reuse it.
-
You can put it away and use it again when you go shopping.
-
Put it away and you can use it later.
Haha advocate that people use cloth bags or paper bags.
A new type of environmentally friendly plastic bag is here, which can be decomposed when put into water, invented by Chinese college students!
Be careful not to burn, as this will release toxic substances.
You can store it and then take it out when you need it in the future, for example, it can be used for garbage or some other items, and one bag can be used for multiple purposes, which helps to protect the environment.
KFC has seized the loophole of the regulations "It is forbidden to use plastic bags with a thickness of less than that"!! However, KFC's breakfast bags are paper bags!! >>>More
