Humans are desperately trying to make plastics, but they don't know how to dispose of them. Humans can't live without plastics in their daily lives, but they talk about the discoloration of waste plastics. Today, the fate of plastic waste is dire, with the results showing that most of the plastic currently ends up in landfills or the natural environment. The largest market for plastics is packaging, and in high- and middle-income countries the proportion of plastics in MSW increased from less than 1% in 1960 to more than 10% in 2005. A new study shows that in the next 30 years, people will produce four times as much plastic waste as they do now.
Researchers report in Science Advances that by 2015, people produced nearly 8.3 billion tons of plastic, of which 6.3 billion tons turned into waste, of which only 9% was recycled and 12% was incinerated (i.e., burning). or pyrolysis and other heating methods), 79% accumulate in landfills or the environment.
If these trends continue, researchers predict that by 2050, people will generate about 26 billion tons of plastic waste, more than half of which will end up in landfills or the environment.
Unless the production of new plastic is reduced, recycling will only delay rather than avoid the disposal of plastic waste. Also, burning plastic can negatively impact the environment and health. "What's more, none of the commonly used plastics is biodegradable, in other words, plastic waste accumulates and does not break down." The study leader, Roland of the University of California, Santa Barbara, USA Geyer said.
As a result, by the new millennium, there will be countless plastic waste piled up everywhere on the earth.
