Many years ago, China explicitly prohibited restaurants from using gutter oil or recycled oil to cook for consumers, because eating gutter oil and recycled oil would bring very serious harm to consumers' health, and some unscrupulous merchants would still choose to use recycled oil and gutter oil as edible oil in order to obtain higher benefits and rewards.

Employees of a hotel in Chongqing successively scooped up oil in the trash can. Once the video about this incident broke out on the Internet, many people paid attention to it and quickly rushed to the hot search. If the store uses these recycled waste oil for consumers at this time, then this behavior of the merchant is obviously illegal and needs to bear corresponding criminal responsibility. However, if such oil is sent to a special processing plant to process soap or various cleaning products, it is very meaningful to recycle such oil. The hotel's response to this incident is that it wants employees to collect all these oils and sell them to companies and businesses that specialize in processing these oils into detergents. However, netizens did not buy it and asked the merchants to show the corresponding certificates.

After this incident, there are many points worthy of our attention. If the merchant only sells the oil to the detergent processing factory at this time, then it is no problem for the merchant to do so. However, if the merchants collect oil for others to eat under the guise of selling secondary recovered oil, then they need to bear very serious criminal responsibility at this time. Because businesses are likely to cause very serious damage to consumers' health.

These oils can be purified into soap or detergent with strong cleaning ability as long as they are purified and added with appropriate amount of alkali. Some recovered oil can be reused in this way, which can actually save a lot of resources and will not cause very serious harm to human body.
