Household or restaurant leftovers, food processing waste, leftovers or industrially produced organics are all called organic waste. Common food waste disposal methods include feeding pigs, making fertilizer or throwing garbage trucks, etc. Industrial waste requires special treatment by environmental protection operators. Due to the outbreak of African swine fever, the virus can exist in the environment for more than 100 days in refrigerated pork and 1,000 days in frozen pork. To avoid food chain infection caused by food waste, the government has banned food waste from feeding pigs.
