<\/p>\n\u201cWe all knew there was a rapid and extreme increase in plastic production from 1950 until now, but actually quantifying the cumulative number for all plastic ever made was quite shocking,\u201d says Ms Jambeck , University of Georgia environmental engineer who specializes in studying plastic waste in the oceans.<\/p>\n
The new study, in the peer-reviewed journal Science Advances, is the first global analysis of all plastics ever made\u2014and their fate. Of the 8.3 billion metric tons that has been produced, 6.3 billion metric tons has become plastic waste. Of that, only nine percent has been recycled. The vast majority\u201479 percent\u2014is accumulating in landfills or sloughing off in the natural environment as litter. Meaning: at some point, much of it ends up in the oceans, the final sink. <\/p>\n
If present trends continue, by 2050, there will be 12 billion metric tons of plastic in landfills. That amount is 35,000 times as heavy as the Empire State Building<\/p>\n
Roland Geyer, <\/a>the study\u2019s lead author, says the team of scientists are trying to create a foundation for better managing plastic products. \u201cYou can\u2019t manage what you don\u2019t measure,\u201d he says. \u201cIt\u2019s not just that we make a lot, it\u2019s that we also make more, year after year.\u201d<\/p>\n Half the resins and fibers used in plastics were produced in the last 13 years, the study found. China alone accounts for 28 percent of global resin and 68 percent of polyester polyamide and acrylic fibers.<\/p>\n Geyer, an engineer by training, specializes in industrial ecology as a professor at the University of California, Santa Barbara. He has studied various metals and how they\u2019re used and managed. The rapid acceleration of plastic manufacturing, which so far has doubled roughly every 15 years, has outpaced nearly every other man-made material. And, it is unlike virtually every other material. Half of all steel produced, for example, is used in construction, with a decades-long lifespan. Half of all plastic manufactured becomes trash in less than a year, the study found.<\/p>\n Much of the growth in plastic production has been the increased use of plastic packaging, which accounts for more than 40 percent of non-fiber plastic.<\/p>\n Tallying plastic waste around the globe<\/i><\/b><\/p>\n The same team, led by Jambeck, produced the first study that assessed the amount of plastic trash that flows into the oceans annually. That research, published in 2015, estimated that 8 million metric tons of plastic ends up in the oceans every year<\/a>. That is the equivalent to five grocery bags of plastic trash for every foot of coastline around the globe.<\/p>\n \u201cWe weren\u2019t aware of the implications for plastic ending up in our environment until it was already there,\u201d Jambeck says. \u201cNow we have a situation where we have to come from behind to catch up.\u201d<\/p>\n Gaining control of plastic waste is now such a large task that it calls for a comprehensive, global approach, Jambeck says, that involves rethinking plastic chemistry, product design, recycling strategies, and consumer use. The United States ranks behind Europe (30 percent) and China (25 percent) in recycling, the study found. Recycling in the U.S. has remained at nine percent since 2012.<\/p>\n \u201cWe as a society need to consider whether it\u2019s worth trading off some convenience for a clean, healthy environment,\u201d Geyer says. \u201cFor some products that are very problematic in the environment, maybe we think about using different materials. Or phasing them out.\u201d
