Contracting hotel bowls and chopsticks

According to TV exposure, many disposable bowls and chopsticks used in big hotels are processed by small workshops, but those bowls and chopsticks have not been sterilized at high temperature and are washed casually. However, sewage flows in the processing chamber. The cost of processing them is only a few cents for the hotel, and selling them to our customers is one yuan, which means that the hotel can earn tens of thousands of dollars a year just for bowls.
