Study: 1M to 2M tons of U.S. plastic trash disposed improperly
More than a million tons a year of America’s plastic trash isn’t ending up where it should. The equivalent of as many as 1,300 plastic grocery bags per person is landing in places such as oceans and roadways, according to a new study of U.S. plastic trash.
In 2016 — the last year enough data was available and before several countries cracked down on imports of American waste — the United States generated 46.3 million tons of plastic waste, by far the most in the world.
Between 2.7% and 5.3% of that was mismanaged — not burned, placed in landfills or otherwise disposed of properly, according to a study in Friday’s journal Science Advances. Between 1.2 million and 2.5 million tons of plastic generated in the U.S. were dropped on land, rivers, lakes and oceans as litter, were illegally dumped or shipped abroad then not properly disposed of, the study found.
Previous studies hadn’t put the United States among the 10 worst offending nations for plastic waste in oceans. That’s because the U. S. Environmental Protection Agency only tracks what goes into official parts of the waste stream such as landfills and recycling centers, and its data doesn’t capture the dirtier aspects of plastic trash disposal, study authors said.
So some researchers from previous studies decided to look deeper into what happens to U.S. trash and found so much is improperly handled that America ranks as high as the third worst ocean plastic polluter. The study estimated that 560,000 to 1.6 million tons of U.S. plastic waste likely went into oceans.
“We are facing a global crisis of far too much plastic waste,” said study lead author Kara Lavender Law, an oceanography professor at the Sea Education Association in Cape Cod, Massachusetts.
