It is recommended to wrap the heating bag after use and throw it into other kinds of garbage. Usually, the main component of self-heating hot pot is quicklime, which reacts with water and releases a lot of heat. The highest temperature can reach 150℃, and the steam temperature can reach 200℃, which is the principle of self-heating chafing dish heating. Therefore, for the sake of safety, don't throw away the hot pot after eating it. Instead, we should make the heating bag fully react with water, wrap it in plastic bags after it is completely cooled, and finally put it into the classified garbage, otherwise the unreacted quicklime in the heating bag will react again when it meets water.
