What is ethanol-blended gasoline compared to that? Even waste oil and diesel have appeared!

“Diesel made from \"gutter oil\" is now available for sale in Shanghai for the first time; it costs 5.85 yuan per liter, which is 0.3 yuan less than regular diesel. According to a report in the Guangzhou Daily (reported by multimedia journalist Zhou Yuwu with photographic coverage), the National Development and Reform Commission announced that as of the 1st, the sale of regular diesel with a sulfur content higher than 10 ppm would be halted nationwide. It was at this time that a new type of biodiesel was officially introduced to the market in Shanghai. Two Sinopec gas stations in Shanghai have recently started selling B5 biodiesel made from \"gutter oil\". As of November 3, the price of this fuel was 5.85 yuan per liter, which is 0.3 yuan cheaper than regular diesel. This marks the first time in China that diesel produced from gutter oil has entered the retail market for finished fuels. 　　Biodiesel is a clean, renewable fuel that can directly replace petrochemical diesel or be used in combination with it to reduce pollutant emissions. The B5 biodiesel officially launched in Shanghai is composed of about 5% biodiesel and about 95% petrochemical diesel, with the 5% biodiesel coming from kitchen waste oils, commonly known as \"gutter oil\". 　　Recently, a reporter visited the Weisan Gas Station of Sinopec at Pudong Airport in Shanghai, which supplies B5 biodiesel. As this gas station is located near the transportation hub of Pudong Airport, trucks that come here to fill up with diesel arrive one after another, resulting in heavy traffic. The station is equipped with a relatively large number of diesel fueling nozzles – over 10 in total, of which 2 are used for supplying biodiesel. Staff at the gas station told reporters that previously, biodiesel was mainly supplied to designated vehicles such as sanitation trucks, but now regular vehicles can also choose to use it as needed. 　　Some people were cautious during the pilot period. Journalists interviewed several truck drivers at random and found that they had little knowledge about biodiesel. A driver surnamed Wang told the journalists that he had never heard of biodiesel, but if everyone else used it, he would be willing to give it a try as well. Another driver surnamed Feng said that he had heard of biodiesel; since he had never used it, he only knew that one liter of biodiesel is not as durable as one liter of conventional diesel. He was also concerned about its impact on the car’s engine, so he would wait and see before trying it out. Another driver who was adding biodiesel by himself told the reporter that this type of fuel is slightly cheaper, and he wanted to give it a try to see if it worked well. 　　In fact, before it was officially introduced to the market, the relevant parties had already gained some understanding of the use of biodiesel through pilot projects. Data shows that as of September 30, 104 buses in Shanghai were using biodiesel, having traveled a total of 15.6072 million kilometers and consuming 5.839 million liters of blended fuel ； 32 waste management vehicles have traveled a total of 83,100 kilometers, consuming 23,800 liters of biodiesel. 　　At present, the centralized and standardized collection, transportation, and disposal of kitchen waste oils in Shanghai amount to around 120 tons per day, resulting in the production of over 30,000 tons of biodiesel (BD100) per year. According to the plans of the relevant parties, pilot projects will first be launched this year at Sinopec Fengxian Zhuangxing Gas Station and Sinopec Pudong Airport Weisan Gas Station in Shanghai, after which the initiative will be gradually rolled out across the entire city based on the results of these pilots.
