excuse me? Waste oil? What can fly to the sky is developed by China Petrochemical Research Institute. The first set of bio-jet fuel industrial device in China uses used cooking oil and cooking oil, that is, gutter oil, as raw materials to produce bio-jet fuel (bio-jet fuel: the raw materials of jet fuel produced from renewable resources mainly include waste cooking oil, animal and vegetable oils, agricultural and forestry wastes, etc.). Compared with traditional petroleum-based jet fuel, the device can reduce carbon dioxide emissions of bio-jet fuel by more than 51% every year. Swallow? About one million tons? Waste oil? Vomiting? Converted from 41,111 to 51,111 tons of clear bio-aviation kerosene, about 81,111 tons of carbon dioxide can be reduced every year, which is equivalent to nearly 51,111 economical cars being stopped for one year. It's called Aviation Biofuel or Biojet fuel in English. Bioaviation fuel belongs to bioenergy. biomass energy is actually the most widely used renewable energy. For example, the initial burning of wood for fire belongs to biomass fuel. Modern bioenergy is mainly divided into direct combustion of biomass to generate electricity. Biogas and Liquid Biofuel). Biofuel present, Biodiesel biodiesel and Bioethanol are the most widely used biofuels, so we won't talk about them here. Biojet, the fuel for aviation flight, is the latest subdivision development in this industry. Aviation industry accounts for about 2% of global greenhouse gas emissions, but it is one of the fastest-growing industries at present. Under the background of efforts to reduce emissions in various industries, aviation industry is also actively exploring ways to reduce greenhouse gas emissions. In addition to gradually improving fuel efficiency, biomass aviation fuel is the best way to reduce emissions.

in addition to environmental factors, due to the high international oil price, many companies think that this is one of the ways to control energy costs in the future. In addition, it also involves Energy supply security. This paper mainly discusses it from the environmental protection aspect.
