During the World Wildlife Fund’s Plastic Policy Summit in March in Washington D.C., I grabbed coffee in a white ceramic mug provided by the convention venue. Reusable mugs seemed unusual amid today’s prevalence of single-use cups, prompting me to reflect on how we have normalized single-use: I bought yogurt and soda in returnable bottles in Beijing; generations before us grew up with reuse. Why did we move away from it?

Food takeaway has become a symbol of urban lifestyle convenience in China, but the resulting single-use plastic (SUP) waste has become a costly environmental and economic burden. In 2020, urbanites ordering on food delivery apps generated 37 billion SUP containers and a small fraction was recycled. According to a report by Pacific Environment, 88.5% of SUP waste in China is landfilled, incinerated, or leaked to the environment. Food and beverage packaging is the number one contributor to China’s SUPs.
