We all know that recycling rubbish is very important. But sometimes it is not so convenient when we can’t find a recycling bin anywhere.

Now a team of middle school students from the US has solved that problem by designing their Recycling Bin app ( 应用程序 ).

This app encourages people to recycle. It provides users with a map of local recycling centers. And it allows them to save places as favorites on   it  . This app also reminds users to recycle.

The group of nine sixth-graders is from STEM Center Middle School. They came up with the idea as part of a school project for the Verizon Innovative App Challenge. Their school provided professional app training. It gave 10 teams Samsung tablets ( 平板 ) as prizes.

The challenge wanted to develop students’ interest in science, technology and engineering. In this contest, students showed an app design that could solve a problem in their school or city. The nine students came up with the idea for Recycling Bin when they saw a need for more recycling.

“ We thought that this would really help a lot of people, ” Jaden Hilkemann, 12, told Time For Kids.

They kept their design easy so that anyone could use it. Now the free Recycling Bin app has been put into use in the Google Play app store for Android phones or tablets.

“ I was so excited when it went up at the app store, ” Seralyn Blake, 12, said. “ A lot of my family members downloaded ( 下载 ) the app. It was pretty cool. ”
