I saw plastic greenhouses as far as the eye can see from the train as I traveled across Shandong Province to visit the Shandong Academy of Agricultural Sciences. Ninety percent of the world’s plastic greenhouses are in China, covering 3.3 million hectares, about the area of Maryland, with the majority in Shandong.

In 2017, the Green Volunteer League of Chongqing, an environmental NGO, filed a suit against China’s three biggest food delivery companies—Meituan, Baidu, and Ele.me—for damaging the environment by generating excessive waste. Specifically, these three e-commerce platforms provided consumers with single-use chopsticks that consumed 6,700 trees every day as well as massive amounts of plastic containers, bags, and utensils. Today, over 400 million Chinese are regular users of food delivery. Since summer 2019, daily app use for Meituan was over 30 million orders, generating 100 million plastic containers every day—enough to carpet 360 football fields.

Coal has long been China’s “black gold,” supplying over half of the nation’s electricity. Yet as coal’s energy share decreases due to domestic action to reduce air pollution and greenhouse gas emissions, a new coal industry is emerging. In China’s arid northwest, eight plants are pulverizing coal chunks and “cooking” coal powder into something more valuable than power—or maybe even gold. These coal conversion plants, soon numbering over 20, churn out chemicals to produce plastic.

Usually after dinner, Mr. Ma would take off his shirt, shut the door, and begin work making plastic pellets from scrap. But tonight, he sits in his darkened yard staring at two SUV-sized plastic processing machines and a bundle of colorful scrap plastic. No lights are on, no machines grind, and no familiar theme song of CCTV-1 plays in the background. Walking through other villages in Wen’an County, more men meander around their yards filled with the same idle processing machines and mini-mountains of scrap plastic. Most have never studied English, but they are fluent in the language of plastics, sprinkling words like ABS, PP, and PVC into their conversations. They are the owners of small plastic scrap recycling workshops that were once booming—but are now silent.

Once a designated “recycling bin” for the world’s post-consumer scrap, China said no more when it instituted a ban on scrap imports in 2018. Countries that previously sent bulks of waste to China, such as plastic, paper, and electronics, are grappling for solutions in the face of China’s “Operation National Sword.” For example, U.S. municipalities that shipped 4,000 shipping containers per day in 2016 to China are now investing in incinerators or cutting recycling programs altogether. 

Our world is drowning in plastic pollution with nearly 8 million tons of single-use plastic and some 700,000 tons of abandoned fishing gear leaking into marine ecosystems each year. Plastic waste endangers marine species. For example, animals become entangled in abandoned nets. Marine birds, fish, whales and sharks are sickened or die when they accidentally ingest plastic. According to a 2017 study, around 90 percent of single-use plastic that pollutes our oceans comes from 10 rivers, 6 of which are in China. No Avenger superheroes can make this problem go away; rather the world needs heroic efforts by consumers, businesses, and governments to curb these plastic leaks. Encouragingly, China’s war on pollution has catalyzed new bottom-up activism and top-down policies that are starting to spur action to reduce plastic leakage.

In early January of this year, China’s “National Sword” policy banned imports of non-industrial plastic waste. The ban forces exporting countries to find new dumping grounds for their waste, which is estimated to total nearly 111 million metric tons by 2030. China’s decision has exposed deep structural flaws and interdependencies in the global waste management system. Western countries that have long depended on China to take their garbage are now struggling to deal with mounds of plastic trash, while China lacks the low-priced labor needed to effectively sort and process waste.

Plastics. From the devastating effects of plastic pollution on our oceans, to the news that plastic bottles likely pollute the drinking water they contain, plastic pollution—the theme of this year’s Earth Day—has been a highly visible issue, and we’ve seen some notable progress on fighting the plastic battle.
