With the development of economy, people's living standard is constantly improving. People's demand for food is also increasing. With the increase of food consumption, the production of food waste is also increasing. Therefore, the increase of food waste results in the increasing proportion of food waste in urban garbage. Compared with other waste, food waste is more difficult to deal with and more harmful to the environment. Because the treatment technology of food waste is not perfect, it may cause secondary pollution in the process of treatment. Food waste has always been a concern of people and there are many organic compounds and nutrients in food waste. This part can be used to produce biofuels to solve the current energy crisis, it can also be a good way to deal with food waste to prevent food waste from polluting the environment.
Starting from food waste, this paper introduces the definition, source and treatment of food waste. The treatment methods of food waste mainly include mixed landfill, incineration, anaerobic fermenta-tion, aerobic composting and livestock feed. Among them, the two treatment methods of mixed land-fill and incineration are banned by many countries because of their disadvantages. The following arti-cle introduces the definition, application and how to use food waste to produce biofuels. In this part, the production of biogas by anaerobic fermentation, transesterification and biodiesel, bioethanol and butanol by ABE fermentation are introduced respectively.
