Wednesdays and Fridays are very busy for Liu Wei．She is an accountant （会计） for a recycling company（公司）．On those days，many customers come to the company with boxes full of waste paper or empty plastic bottles．Liu，with other workers，weighs the things and takes down the numbers．But she works for only 20minutes and then goes back to…study．
Liu，15，is actually a student in Nanjing Baijiahu Middle School．Both the company workers and the customers are students．The company collects the waste from every class and sells it at the end of every month．The money will be given to the local Red Cross Society．
Wang Xiaogen，the headmaster of the school，set up the company in 2008and got students to run it．He thought that the company would not only help students care more about the environment，but also improve their abilities in many ways．

Jiang Qinyou，15，the chairman of the company，said he felt as though he became one of the masters of the school．He holds meetings every Friday and talks with school officials about the current situation．
