If you turn over a plastic bottle, like those we use to drink water, you'll notice a number "1"— that means it's made of a material called PET. Some bags, like the kind that holds milk or coffee, get a "2", meaning they're made of a material called HDPE. At material recovery factories, plastics get sorted (分类) based on these numbers (they go up to 7), which shows how recyclable (可回收的) they are.

Plastic marking numbers 1 and 2 are recyclable. They can be made into carpet, clothing, plastic package, as well as other products, according to Live Science.

Recycling gets more difficult with higher numbers, called "mixed plastic". This waste makes up 69% of all the plastic we use in the daily life. It's much more expensive to deal with than numbers 1 and 2. In the past, mixed plastics would be sent to other countries. But two years ago, almost no country was allowed to buy foreign plastic waste.

Recycling companies had to find a new market, but many failed. For example, in Los Angeles, recycling companies still won't recycle any plastics with numbers higher than 2. Instead, they are burying or burning them.

According to Live Science, what the USA needs is machines that can be used to recycle other kinds of plastic. But Hocevar, a scientist, comes up with a different solution: "The really simple answer is there isn't so much throwaway plastic in the world."

Someone may ask, "Is recycling worth it?" For bottles with "1" or"2", the answer is "yes", said Hocevar. There's also a growing market for plastics marked "5", a flexible (灵活的) plastic that includes yogurt containers (酸奶容器). For other numbers, the answer was simpler; a "no" on numbers3, 4, 6 and7.
