Beginning in January
2018, China’s new “National Sword” policy banned plastic waste from being
imported. The Chinese government stated that this law was passed in an effort
to protect the environment and people’s health.
Before the passing of
this law, China imported more than 106 million metric tons of the world’s
plastics from countries like the U.S., Japan, and Germany. This large amount of
plastic, about 45 percent of the world’s plastic waste to be exact, has been
exported to China since the early 1990s. China profited from this arrangement
by taking plastic waste and recycling it, then creating new products for
export.
Now that China refuses to
take half the world’s plastic, what will happen to the leftover waste?
According to the authors
of a new study published in Science
Advantage, it is already beginning to pile up. Amy Brooks, lead
author of the study, stated, "We have heard reports of waste accumulating
in these places that depend on China,” with some of it ending up in landfills.
The study estimates that by 2030, 111 million metric tons of plastic waste will
be displaced because of this new ban.
Other countries, like Malaysia,
Thailand, and Vietnam, are still importing and recycling plastic. For example,
the U.S. sent an estimated 137,044 metric tons of plastic to Vietnam in 2017
alone. However, many of these countries "lack the infrastructure to
properly manage it." In fact, according to Jenna Jambeck, another of the
study’s authors, Vietnam has already capped how much waste it will take. The
country announced that it would not accept any more imports of plastic until
October.
Jambeck noted that, “Not
one country alone has the capacity to take what China was taking. What we need
to do is take responsibility in making sure that waste is managed in a way that
is responsible, wherever that waste goes — responsible meaning both
environmentally and socially." This could be a tough undertaking for some
countries, like the U.S., Japan, and Germany. These countries top the list of
exporters of plastics. Between 1988 and 2016, the U.S. exported an estimated
26.7 million tons of plastic. Surprisingly, the U.S. is not the number one
exporter. Hong Kong is the biggest exporter of plastic waste, at an estimated
56.1 million tons. For countries like these, it is more economical to export
plastics than to recycle them.
Since the rapid expansion
of disposable plastics in the 1990s, particularly single-use containers,
exports of plastic have steadily grown. Yearly global exports grew 723 percent,
to around 15 million megatons, from 1993 to 2016. To minimize this, measures
will need to be taken to lessen the amount of plastic waste, particularly
eliminating the number of single-use containers being produced. Marian Chertow,
the director of the program on solid waste policy at Yale, stated,
"There's a tremendous shift in the market when China won't take half of
these plastics. I really think that this export mindset that has developed in
the U.S. is one that has to change."
