NEW YORK (NYTIMES) - When more than 180 nations agreed last year to place strict limits on exports of plastic waste from richer countries to poorer ones, the move was seen as a major victory in the fight against plastic pollution.
But new trade data for January, the first month that the agreement took effect, shows that US exports of plastic scrap to poorer countries have barely changed, and overall scrap plastics exports rose, which environmental watchdog groups say is evidence that exporters are ignoring the new rules.
The US companies seem to be relying on a remarkable interpretation of the new rules: Even though it's now illegal for most countries to accept all but the purest forms of plastic scrap from the United States, there's nothing that prevents the United States from sending the waste.
The main reason: The United States is one of the few countries in the world that didn't ratify the global ban.
"This is our first hard evidence that nobody seems to be paying attention to the international law," said Mr Jim Puckett, executive director of Basel Action Network, a non-profit group that lobbies against the plastic waste trade. "As soon as the shipments get on the high seas, it's considered illegal trafficking. And the rest of the world has to deal with it."
The scrap industry says many of the exports are quite likely compliant with the new rules and that the increase in January reflects growing global demand for plastic to recycle and use as inputs for new products.
Recent history, however, shows that a large of amount plastic scrap exported from the United States does not get recycled but ends up as waste, a reality that was the impetus for the new rules.
The rules were adopted in 2019 by most of the world's countries, although the United States isn't among them, under a framework known as the Basel Convention. Underlying the change was the need to stem the flow of waste from America and other wealthier nations to poorer ones.
Though many US communities dutifully collect plastic for recycling, much of the scrap has been sent overseas, where it frequently ends up in landfills, or in rivers, streams and the ocean.
China, which once accepted the bulk of that waste, in 2018 banned all plastic scrap shipments, declaring that it no longer wanted to be the "world's garbage dump." Since then, US companies have looked to ship plastic scrap waste to countries like Malaysia and Indonesia instead.
Last year, an industry group representing the world's largest petrochemical makers lobbied for United States trade negotiators to press Kenya, one of Africa's largest economies, to continue importing foreign plastic garbage.
But because Basel rules prohibit member nations from trading waste with countries that have not ratified the convention, the new regulations now effectively ban the trade in most kinds of plastic waste between the United States and the rest of the world.
For now, US companies appear to have opted to continue to put their scrap onto ships out of the country at an even faster pace. And the scrap industry says that much of the plastic that was being shipped in January is considered legitimate under the Basel rules by the companies around the world that are purchasing it to use in manufacturing.
"The contention that all of these plastic scrap exports from the United States are not legitimate is factually incorrect," said Ms Adina Adler, vice-president of advocacy at the Institute of Scrap Recycling Industries, a trade group.
Data for January showed that exports of scrap plastic from the United States edged upward, to 48 million tons from 45 million tons the previous January. Exports to poorer nations were virtually unchanged from a year ago, totaling 25 million tons.
Advocates say that there are clear red flags in the data. Malaysia, which had signed on to Basel, remained a major destination for US scrap plastic in January.
For example, a shipment containing bales of plastic scrap left Los Angeles on Feb 14 and is scheduled to arrive at a port outside the Malaysian capital, Kuala Lumpur, this month, according to data provided by Material Research, a Maine-based research firm.
That shipment, sent by Georgia-based Sigma Recycling Inc on a cargo ship operated by French shipping company CMA CGM.
In a statement, Sigma said that its shipment involved "clean pre-sorted plastic scrap" and that the company was confident it would be accepted by Malaysian customs. "Sigma has followed all the rules and regulations to best of our knowledge," the statement said.
In a separate statement, CMA CGM Group said it was "totally committed to responsible trade" and would not knowingly violate international standards. "According to documentation received at the time of booking, the commodity carried is not in violation of the Basel Convention," the CMA CGM statement said.
If the United States were to ratify the Basel agreement - which would require Congress to pass legislation - traders found to be shipping plastic waste overseas could be prosecuted. Short of that, the US government is limited in its ability to stop plastic waste exports.
Still, growing awareness could start to change things, said Mr David Azoulay, a Geneva-based lawyer with the Centre for International Environmental Law, a non-profit environmental law firm.
Even ardent opponents of the agreement may be shifting their position. The Institute of Scrap Recycling Industries has opposed the United States joining the Basel agreement, arguing that it hampers legitimate trade of plastic scrap that can be recycled. This week, Ms Adler said that the trade group's position on Basel was under an internal review.
"You're starting to see an outcry in countries being flooded with waste. And we are already seeing more countries starting to put their foot down," Mr Azoulay said. And the more Americans "learn that their waste ends up in fields in Malaysia, or openly burned in Indonesia or Vietnam, it's not going to sit very well."
"I do think that we're in a pivotal moment," he said. "Is illegal trade of waste going to continue to happen? Yes, without a doubt. But can it continue at the scale that it is currently happening? I don't think so."
