1) Affect agricultural development. The accumulation of waste plastic products in the soil will affect the absorption of nutrients and water by crops, resulting in reduced crop yields.
2) Pose a threat to the survival of animals. Waste plastic products discarded on land or in water bodies are swallowed by animals as food, resulting in the death of animals. Last year, nearly 1,000 sheep from 20 herdsmen in Qinghai Lake were killed, causing an economic loss of more than 300,000 yuan.
Sheep like to eat the oily residue wrapped in plastic bags, but often eat together with plastic bags, because the eaten plastic remains in the stomach for a long time and is difficult to digest, these sheep's stomachs are crowded, can no longer eat, and can only be starved to death. This kind of thing is not uncommon in zoos, pastoral areas, rural areas, and oceans.
3) Waste plastics will not only occupy a large amount of land with landfill, but also the occupied land will not be restored for a long time, affecting the sustainable use of land. If the waste plastic products that enter the domestic garbage are landfilled, they will not degrade for 200 years. It is extremely harmful to the land, changing its pH, affecting the absorption of nutrients and water by crops, resulting in reduced agricultural yields, and as for plastic products discarded in water or on land, it not only affects the environment, but also leads to death if passively swallowed.
This upsets the ecological balance.
4) High temperature decomposes toxic substances, plastic products have no toxic substances, but because its reuse equipment is not perfect, the process is simple, and many manufacturers do not have a legal business license, resulting in the reproduction of plastic products when the temperature reaches 65, toxic substances will precipitate and seep into the food, which will cause harm to the liver, kidneys, reproductive system and central nervous system and other important parts of the human body.
The plastic structure is stable, not easy to be degraded by natural microorganisms, and does not separate in the natural environment for a long time. This means that if waste plastic waste is not used, it will become a pollutant in the environment and continue to accumulate forever, which will cause great harm to the environment.

1. Waste plastic products discarded on land or water are eaten by animals by mistake, resulting in the death of animals, which will pose a threat to the survival of animals. 2. Incineration of waste plastic products will produce toxic gases, which will endanger human health once inhaled. 3. Plastic products are disposed of with landfills, which occupy a large amount of soil and are difficult to decompose, which will make the soil barren.
4. Plastics are made from petroleum refining products, and petroleum resources are limited, which is not conducive to the reuse of resources.
5. **When using waste plastics, it is very difficult to classify and it is not economically cost-effective.
6. The accumulation of waste plastic products in the soil affects the absorption of nutrients and water by crops, resulting in reduced crop yields.
Plastic products are a general term for life, industrial and other products processed from plastic as the main raw material. Including plastic as raw material injection molding, blister and other products of all processes. Plastic is a kind of synthetic polymer material with plasticity.
Together with synthetic rubber and synthetic fibers, it forms the three major synthetic materials that are indispensable for daily life. Specifically, plastic is a material that uses natural or synthetic resin as the main ingredient, adds various additives, and can be molded into a certain shape under certain conditions such as temperature and pressure, and keep the shape unchanged at room temperature.
Hello everyone, I'm Henan Ruiqite. Recently, more customers have come to consult some plastic products that are deformed or soft after molding, how to solve this problem? >>>More
2.There are three small ways to repair plastic products: 1 >>>More
Everyone knows to dispose of waste items such as newspapers, drink bottles, etc., so what about the old stuff that is piling up in your utility room or basement? How can they be dealt with effectively without polluting the environment? Today, two experts from the environmental magazine GRIST will answer your questions: >>>More
Probably not! Our customers also use a kind of oil when making pellets, but I don't know what kind of oil.
I used to work in the plastics industry, and if the bottle body is transparent plastic, it is generally PET, and the cap and bottle body are generally made of different materials. But not necessarily. Anyway, why are you studying this ==
