According to a study in the United States, plastic products emit a variety of greenhouse gases after exposure to sunlight. In the current global warming situation, this will cause greater environmental damage to the environment.
Researchers at the University of Hawaii test polycarbonate, acrylic, polyethylene, polyester synthetic fibers and other compounds commonly used in the production of plastic products such as shopping bags, building materials, etc. The entire experimental period is 212 days. According to the experimental results, these compounds When degraded in sunlight, it releases a variety of greenhouse gases such as methane and ethylene.
According to previous research, humans have never regarded plastic as an important source of greenhouse gases.
According to the researchers, the 'most prolific' of the compounds that release methane and ethylene is polyethylene. It is commonly used in plastic shopping bags and is the world's most synthetic and abandoned synthetic polymer.
