How much land can be polluted by a plastic bag Exact number 10

Plastics are generally non-toxic, and their pollution lies in the pollution caused by combustion treatment! Buried in the soil is difficult to degrade, resulting in poor soil aeration and destroying the ecology! Not like other pollutants!

A single plastic bag can pollute a square meter of land. The raw pants of the plastic bag are polymer compounds, its structure is stable, and it is not easy to be degraded by natural microorganisms, and it takes more than 200 years for the non-degradable plastic bag to rot naturally. Hand plastic bags discarded on land and water bodies can be swallowed as food by animals and fish, causing death or affecting the growth of animals and fish.

Environmentally friendly plastic type bag:

With the development of science and technology, all kinds of materials that can replace traditional PE plastics have appeared, including PLA, PHAS, PBA, PBS and other polymer materials, which can replace traditional PE plastic bags. Environmental protection plastic bags have been widely used: supermarket shopping bags, roll fresh-keeping bags, plastic film, etc. have been widely used in China.

Eco-friendly plastic bags include recycled plastic bags and new plastic bags. In the process of producing plastic bags, the plastic bags with degradable masterbatches are called degradable plastic bags, and the degraded plastic bags can be automatically decomposed after 90 days under certain conditions. The existing eco-friendly ones decompose relatively quickly, possibly within a year.

There are also faster, Olympic environmentally friendly plastic bags can be decomposed 72 days after discarding.

One plastic bag will pollute 0 06 square meters of land.

It takes decades or centuries for typical plastics to break down into environmentally harmless (less harmful) pieces, or into carbon dioxide and water, and then back into the natural cycle. Refractory waste plastics lie dormant underground for about 200 years before decomposing and contaminating the soil.

Landfill degradable plastic waste not only occupies a large amount of land, but also the occupied land cannot be restored for a long time, seriously affecting the sustainable use of land. If the waste plastic products in the domestic waste are buried, they will not be degraded for 200 years, and they will be completely degraded in 1000 years.

If a plastic bag pollutes a square meter of land, if an average person throws away an average plastic bag every day, a city of 1 million people will lose 1 million plastic bags a day.

That's about 60,000 square meters of land polluted every day.

Polluting square decimeters of land.

Will pollute 0 06 square meters of land!

A single plastic bag can pollute a square meter of land. If an average person throws away one plastic bag a day, a city of 1 million people will throw away 1 million plastic bags a day, causing about 60,000 square meters of land pollution every day.

The raw material of plastic bags is polymer compounds, which are stable in structure and not easy to be degraded by natural microorganisms, and it takes more than 200 years for non-degradable plastic bags to rot naturally. If the waste plastic bags are not mixed, they will be mixed in the land, causing soil compaction, affecting the absorption of nutrients and water by crops, and resulting in reduced crop yields.

Waste plastic bags disposed of on land and in water bodies can be swallowed by animals and fish as food, resulting in the death or growth of animals and fish.

It seriously pollutes environmental sanitation and increases the workload of sanitation workers. Every day in windy weather, plastic bags are blown all over the sky, some hanging on the treetops, some hanging on power lines, and it is time-consuming, laborious and dangerous to remove. If it is incinerated at will, it will emit toxic gases, pollute the air and affect people's health.

Serious endangerment to human health. Polyvinyl chloride monomer, the main component of plastics, can damage the human nervous system, liver and kidneys after being absorbed; When plastic is burned, the fumes released contain large amounts of carcinogenic compounds.

If a plastic bag pollutes a square meter of land, if an average person throws away an average plastic bag every day, a city of 1 million people will lose 1 million plastic bags a day.

That's about 60,000 square meters of land polluted every day.

Generally, it will take decades or hundreds of years for plastics to be degraded into environmentally harmless (less harmful) fragments or into carbon dioxide and water, and return to the natural cycle. It takes about 200 years for refractory waste plastics to decay when buried in the ground, and they seriously pollute the soil. Degradable 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, which will seriously affect the sustainable use of land.

If the waste plastic products that enter the domestic garbage are landfilled, they will not be degraded for 200 years, and it will take 1000 years to completely degrade.

Pollution to the ecological environment and landscape. Potential Hazards of White Contamination:

1. Excessive encroachment on land. Plastic waste also stays in nature for a long time

A] According to if every 6 plastic bags can contaminate 1 square meter of land (e.g., landfill disposal, it does not displace).

It can be calculated: 960 plastic bags can pollute the land: 960 6 = 160 (square meters).
