Big cities have shielded their residents from the impact of China’s decision last year to curtail the solid waste it will accept from other countries. But rural and small-town residents are starting to get squeezed by a change that is wreaking havoc on the global recycling market.
Hannibal, Missouri, population 18,000, has stopped accepting recyclable plastics labeled with the numbers 3, 4, 5, 6 or 7, such as yogurt containers and shampoo bottles. Villages near Erie, Pennsylvania, no longer take glass. And in Columbia County, New York, nestled in the Hudson Valley, residents soon will have to pay $50 a year to dump their materials at one of the county’s recycling centers.
China, for decades the world’s largest importer of waste paper, used plastic and scrap metal, last year stopped accepting certain kinds of recyclables and tightened its standards for impurities in scrap bales. In making the changes, China’s Ministry of Environment Protection cited environmental damage caused by “dirty wastes or even hazardous wastes” mixed in with solid waste that can be recycled into raw materials.
Many Americans now have access to single-stream recycling, which spares them the trouble of sorting and separating plastics, paper, glass and metal. But single-stream recycling has created headaches for Chinese processors. Even after sorting at a U.S. recycling facility, a plastic container might make it into a shipment of tin cans. Glass breaks, and shards are mixed in with pieces of paper.
The industry standard for contamination typically ranges between 1 and 5 percent. Under the new policy, China’s standard is 0.5 percent.
“They didn’t just change the policies, they radically changed the entire world market in one fell swoop,” said Joe Greer, director of sales for Buffalo Recycling Enterprises, which accepts recyclables from a number of small towns along Lake Erie.
