Original review passage
A school team compared waste near the canteen before and after a new bin system. They counted only safe items from a distance and asked staff to handle anything sharp. The first count was on Monday,and the second was a week later. There were fewer plastic cups,but more paper bags. The team did not claim that one week proved permanent success. They recommended continuing the count and asking students why they chose different packaging. A useful environmental project combined observation,questions,and a safe method instead of only a cheerful photograph.
