Humans Have Produced Whopping 9 Billion Tons of Plastic

A new study, which is the first global analysis of all mass-produced plastics ever made, finds that since large-scale manufacturing of plastics took off in the 1950s and until 2015, humans have produced approximately 9 billion tons (8.3 billion metric tons) of plastic.

To put that in perspective, all that plastic would be equivalent to 85,567 aircraft "supercarriers" like the USS Gerald R. Ford, which weighs 107,000 tons (97,000 metric tons).

Of those 9 billion tons, half was made in the last 13 years, said Roland Geyer, an associate professor of industrial ecology at the University of California, Santa Barbara, and lead author of the new study, which was published online today (July 19) in the journal Science Advances.

As of 2015, about 7 billion tons (6.3 billion metric tons) of plastic have been disposed of as waste, with only 9 percent of it recycled, 12 percent incinerated, and a whopping 79 percent finding its way into landfills, the researchers report.
