Indeed, paper cups aren't as environmentally friendly as they seem. Only about 11% of recycling plants in the U.S. currently can recycle them, according to the American Forest and Paper Association, because they are typically coated in plastic or have beverage residue. The lack of an 'easily recyclable cup designed for hot beverages' is one reason Dunkin' Brands is still weighing whether to switch to paper, Karen Raskopf, chief communications officer, said.

事实上，纸杯并不像看起来那样环保。美国林业及纸业协会的数据显示，目前美国只有约11%的回收站能够回收纸杯，因为它们通常有塑料覆膜或者有饮料残留。缺少“适合热饮的易回收的纸杯”是Dunkin' Brands仍旧在权衡是否换为纸杯的原因之一，首席公关卡伦・拉斯科普夫(Karen Raskopf)说。

'At this point, we don't know if our end solution will be paper or another material,' she added.

“现在我们还不知道最终解决方案会是纸还是其他材料，”她补充道。

Paper cups are slightly more expensive than foam, usually by a couple cents. Extras like double walls for insulation or plant-based lining to make it compostable add to the price.

纸杯比泡沫塑料一般贵几分钱。像双层隔热的或者内层为可分解植物材料的纸杯价格更高。

McDonald's has been using double-walled paper cups--which have a small pocket of air between them to increase insulation--at about 2,000 restaurants along the West Coast since 2017. Now it is expanding into the Midwest and parts of the East Coast, says Ian Olson, director of sustainability.
