Gutter oil has always been abhorred by the people, never thought that gutter oil will also have a day to become a treasure, from the gutter oil to extract biofuel, in the long run, this regenerative technology is undoubtedly of great value. Our country has a large population, the annual emissions of garbage is huge, gutter oil is also more, the annual production of gutter oil more than 5 million tons. In previous years, gutter oil has always been black-hearted merchants will put them on the table, now it can be refined biofuel, which undoubtedly changed the situation. Gutter oil if it is said to be edible, it will affect people's health, black-hearted businessmen use gutter oil for no other reason than that gutter oil is cheap enough, and now the gutter oil can be refined biofuel, then its value will be doubled, so that the black-hearted businessmen will not choose to return to the table with gutter oil, and the biofeedstock from the gutter oil, in proportion to the use of aviation fuel according to the corresponding ratio, can also effectively reduce the aircraft navigation in the The biofuel extracted from gutter oil, when used in proportion to aviation fuel, can also effectively reduce carbon dioxide emissions from airplanes, which is also beneficial to the ecological environment. This waste to treasure also draws a new way out for the reuse of resources, for example, since it can be used in the kerosene of high-altitude airplanes, can it also be added to other fuels, so that it will be more widely used. This kind of biofuel will not only not affect the combustion efficiency, compared with the traditional fuel it is less polluting, more in line with the current concept of environmental protection. At present, his price per liter is 30 cents cheaper than traditional fuel, in this case for the use of the organization, the amount of money will also be reduced. And in the long run, everything has disadvantages and advantages then, some other waste or garbage is not also can be carried out to turn waste into treasure? As long as the use of the right use, the development is not all will become renewable energy so, in China's new energy conversion will also have a breakthrough progress, which will be a major and far-reaching significance.
