We use apps to order takeout, learn English and shop online. But have you ever imagined that we could deal with rubbish by using an app?
Dou Zheng, 15, a ninth-grader at The High School Affiliated to Beijing Normal University designed(设计) such an app. People can sell recyclable waste (可回收垃圾) like bottles to rubbish collectors. Just like ordering takeout, people can simply make an order on the app and enjoy door-to-door service. This March, Dou won the first prize at the 36th Beijing Youth Science Creation Competition with the app.
The idea for her app came from a real-life experience. On her way home, she always saw roads that were blocked ( 堵 住 ) because of rubbish collectors. “ There are lots of water bottles and cardboard on the roads. It’s a total mess ,” she said.
After doing research on surrounding communities ( 社 区 ), she found that the answer to the problem was to change the way people and rubbish collectors trade.
Last summer holiday, she ordered a lot of takeout, which gave her the idea to design the app. To believe that it would work, she did surveys on WeChat and in the streets. The results showed that eight out of 10 people supported the idea.
However, she didn’t know how to program apps. She read many books and watched videos to learn about programming on her own. “It’s hard. I have to know what a series of complicated codes (代码) mean and then write my own,” she said. Later, with the help of an app called AppMakr, she finished it! “This app made designing my app easier,” she said.
Her app may go online next year. “I’m working on contacting companies to promote (推广) it,” she said.
