When your pen is broken, you think that’s the end of its life. You throw it away. It then joins tons of other garbage that is becoming a big problem in cities.

Each day, about 10,000 tons of waste is produced in Guangzhou, and 17,000 tons of household waste is produced in Beijing.In other countries, the case is similar.“If you’re like most of us, most Americans, you’re making seven pounds (3.17kg) of trash a day,” US writer Edward Humes told CNN. So, an American makes 102 tons of trash in a lifetime.

If you simply throw away that broken pen, it goes to a landfill(垃圾填埋场) and is buried together with many other trash. To prevent polluting the groundwater, workers cover the trash with soil and keep it dry. And your pen will stay there for a long, long time, without having further use.

But it could have a better destination: the recycling bin.Have you ever noticed the different colors of trash bins in the street? Many cities in China have been running a waste-sorting (垃圾分类) campaign. They divide trash into “recyclable waste” and “unrecyclable waste”.

Recycling waste can save energy, reduce greenhouse gas, and keep space free for the unrecyclable trash.Take your pen as an example. At the recycling factory, its metal parts could be taken out and reused to make other things.But recycling is not enough, experts say. Making less waste in the first place is the way forward.

“The best thing to do is just keep using your stuff for as long as you can,” US writer Adam Minter told Time Out magazine.
