Gas station recovery machine oil bottle "two birds with one stone"

At the PetroChina Hankou Youth Road Petrol Station in Wuhan, you will find that each fuel pumping island has a cardboard box of the same size filled with blue small oil bottles on both ends. There are probably a few hundred in a box. What is this? Listen to the explanation of the station leader Wang Jun.

“This is a good idea for our staff to come up with. Our gas station sells Hailong fuel oil. After many customers add fuel oil, the small packaged oil bottle is left. The abandoned fuel bottle is a plastic bottle. A loss will pollute the environment, so I have come up with a good way to collect all the waste oil bottles of the oil treasures in the carton. I did not expect that we also served two birds with one stone. These used oil bottles attracted the curiosity of other customers and they asked what it was. At this time we will sell the fuel bail, and customers will be able to purchase and use it more easily. You see, isn't that turning waste into treasure?” Wang Xiaochang laughed proudly.

His method was promoted in the area, and many gas stations are insisting on recovering the fuel oil waste bottle to avoid the bottle becoming an environmental killer.
