Environmental protection plastic bag decomposition time

The environmentally-friendly decomposition method used today is relatively faster, and may decompose within a year. There are also faster, the Olympic environmental protection plastic bags can be decomposed 72 days after being discarded.

Plastic bags have indeed brought some convenience to our lives, but the convenience at this time brings long-term harm. The value of plastic bags is relatively low. In the process of use, they are scattered in city streets, tourist areas, water bodies, highways and In addition to the "visual pollution" pollution caused by both sides of the railway, it also has potential hazards. The plastic structure is stable, not easily degraded by natural microorganisms, and will not separate for a long time in the natural environment. This means that if waste plastic waste is not recycled, it will become a pollutant in the environment that will permanently exist and accumulate, which will cause great harm to the environment.

First, it affects agricultural development. The continuous accumulation of waste plastic products mixed in the soil will affect the absorption of nutrients and water by crops, resulting in reduced crop yields.

Second, it poses a threat to the survival of animals. Waste plastic products discarded on land or in water bodies are swallowed as food by animals, leading to their deaths. Last year, there were 20 herders on the banks of Qinghai Lake and nearly 1,000 sheep died as a result. The economic loss was about 300,000 yuan. Sheep like to eat the oily residue wrapped in plastic bags, but they often eat them together with the plastic bags. Because the plastic they eat stays in the stomach for a long time and is difficult to digest, the stomachs of these sheep are packed and can no longer eat. Things can only be starved to death in the end. Such things are not uncommon in zoos, pastoral areas, rural areas, and the ocean.

Third, landfilling waste plastics will not only occupy a large amount of land, but the occupied land will not be restored for a long time, which will affect the sustainable use of land. If the waste plastic products that enter the domestic waste are buried, they will not be degraded for 200 years. It is extremely harmful to the land. Changing its pH will affect the absorption of nutrients and water by crops, resulting in reduced agricultural production. As for plastic products discarded in water or on land, not only affect the environment, but if passively swallowed, it will lead to death. This destroys the ecological balance.

Fourth, the high temperature will decompose toxic substances. Plastic products are non-toxic, but because of its recycling ² the equipment used is not perfect, the craftsmanship is simple, and many manufacturers do not have legal business licenses, resulting in plastic products being reproduced at high temperature. When the temperature reaches 65°C, toxic substances will separate out and penetrate into the food, which will cause harm to important parts of the human body such as the liver, kidneys, reproductive system and central nervous system.
