How long does it take for a plastic bag to completely decompose on average?
It takes more than 200 years for plastics to degrade naturally, and 80-100 years for cans. If it is directly buried, it will take up a lot of land after a long time. Recycling glass, metal, plastic and paper and classifying kitchen waste can greatly reduce the amount of waste treated by the existing mainstream waste treatment methods (incineration or landfill).
It takes more than 200 years for plastic bags to decompose naturally. Some newly produced plastic bags can be decomposed in the sun, but most plastic bags are made of high-density polyethylene, which is difficult to degrade. Microorganisms in nature do not regard this substance as food, so they will not decompose it.
Extended data:
It takes more than 200 years for each plastic bag to decompose naturally, which will pollute the surrounding land and water quality, and the power consumption during processing is even more amazing. Most disposable plastic bags used by people are made of polyethylene and polyvinyl chloride, and some of them also contain environmental hormones such as plasticizers and phthalates.
When exposed to high temperature, chemical reactions will occur, which will produce substances harmful to human body. Phthalates will have a serious impact on human reproductive health and immune function. Eating this hot food in plastic bags for a long time will bring immeasurable harm to human health.
