"Ditch oil" has three barriers to become diesel

As the B5 biodiesel blending base of Sinopec Shanghai Petroleum Branch is about to be commissioned and put into use, the speed of the "ditch oil" biodiesel entering the terminal sales market will be further accelerated. This is a good thing that can solve food safety problems, energy conservation and environmental protection. In the face of Shanghai, 200 gas stations supplying B5 biodiesel will be rolled out by the end of Shanghai. With nearly 600,000 tons of biodiesel, the pressure and worries of the sales terminal remain.

Food safety "hanging sword" turns into an energy and environmental protection weapon

"Gutter oil" is like a sword hanging on food safety issues. B5 biodiesel is a kind of green energy that uses waste "ditch oil" and is blended with ordinary diesel fuel in a ratio of 5 to 95 after a series of biochemical reactions. It can not only reduce the harm of petrochemical fuel emissions to the environment, but also It can promote the resource utilization of "ditch oil".

In recent years, biodiesel made from "ditch oil" has attracted attention from various places. In 2017, Beijing and relevant Hebei production enterprises signed an intent agreement to transport Beijing's "ditch oil" to Hebei, and Hebei returned high-quality biodiesel to Beijing, realizing a "win-win" between food safety and atmospheric governance. Chengdu produces more than 100,000 tons of “ditch oil” every year. The local “drain oil” disposal company stated that it wanted to truly prevent the return of “ditch oil” to the dining table. While strengthening source management to achieve “full collection”, it was also necessary to find consumers. To accept "export" of "ditch oil" market.

Just last October, B5 biodiesel officially entered Sinopec's two gas stations in Fengxian District and Pudong New District of Shanghai to start pilot sales. As of early May 2018, B5 biodiesel produced by "ditch oil" has been sold at 33 gas stations in Shanghai, with a total sales volume of more than 23 million liters.

It is understood that Shanghai currently produces more than 30,000 tons of food waste in restaurants and kitchens. According to the preparation ratio, if 200 gas stations can sell nearly 600,000 tons of B5 biodiesel in the future, the “ditch oil” produced by Shanghai throughout the year Will be completely absorbed.

Zuo Xingkai, chairman of Sinopec Shanghai Petroleum Branch, said, "Let biodiesel enter the terminal sales market for refined oil products, it will really open up the 'last mile' of the industrial chain of 'ditch oil' recovery, disposal, utilization and sales."

Biodiesel still has "three barriers"

Raw materials, technology, and cost were once the "three barriers" that hindered biodiesel from moving to the sales terminal of refined oil products. Through policy guarantees, technological research and development, industry subsidies and tax incentives, and the opening of the "window" of Sinopec's terminal sales, the biodiesel that has passed the "three barriers" seems to have seen the "spring" after many years of "winter" in the industry. However, industry insiders told reporters that a large amount of biodiesel needs to cross another "three barriers" in order to be promoted and applied in the end market.

First, the audience market for diesel vehicles is relatively narrow. According to the "China Motor Vehicle Environmental Management Annual Report (2018)" released by the Ministry of Ecology and Environment, nationwide, diesel vehicles only account for 9.4% of the car ownership. "As an ordinary car owner, even if I understand the benefits of biodiesel, I am helpless, because my car and my colleagues and friends almost don't use diesel." Shanghai private car owner Mr. Yang said.

Second, the market is still skeptical of biodiesel. Although the operation of Shanghai buses for more than 10 million kilometers shows that long-term use of B5 biodiesel will not form carbon deposits on the key parts of pistons, valves, fuel injectors and other key parts of car engines, and there are no oil circuit related failures, even Exhaust gas emissions also showed significant improvement. However, there are still many diesel car drivers who have expressed to the gas station employees that they are "fearing that biodiesel made from gutter oil will stick to the engine."

The third is whether biodiesel that still needs subsidies can achieve "independence" in the future. At present, biodiesel is still in the market promotion stage in China. In order to make consumers willing to try B5 biodiesel, Shanghai has come up with a subsidy policy. The price increase of B5 biodiesel is 3 cents cheaper than ordinary No. 0 diesel. However, the energy development supported by subsidies alone is difficult to last for a long time. Whether biodiesel will continue to be recognized by the market in the future with subsidies and parity that will eventually retreat will remain a question.

Diversified applications may become a "secret recipe"

"With the addition of this oil, pollutant gas emissions such as heavy metals and fine particles have been reduced by more than 10%, and the purification efficiency of nitrogen oxides has reached more than 80%. The vehicle power feels not bad, and the black smoke is less. 3 cents per liter is cheaper "Money." On the pump island, Ma Wen, the head of Minqi Gas Station of Sinopec Shanghai Petroleum Minxian Branch, always tirelessly recommends to drivers, hoping that everyone will recognize B5 diesel.

The "face-to-face" oral promotion of employees, the promotion of new media platforms, and the expanded influence of many traditional news media ... The advantages of biodiesel quality and environmental protection are being understood by more and more people, but let every consumer change The skeptical attitude towards biodiesel also requires long-term unremitting publicity and education.

Industry insiders said that opening up the industrial chain of "ditch oil" recovery, disposal, utilization, and sales is only the first step. When the B5 biodiesel refined oil sales terminal is rolled out, it is actually the enterprises and institutions that need to change their attitudes to participate in the application. "The majority of diesel vehicle owners are companies or units. If biodiesel can be promoted and applied at this level, market worries will be greatly reduced."

"In fact, the application range of biodiesel is not limited to vehicles, for example, boilers, ships, power plants, etc. can be applied to biodiesel." Meng Guanghai, general manager of Shanghai Zhongqi Environmental Protection Technology Co., Ltd., said that they are used as "ditch oil "Disposal companies are also actively working with Tongji University and relevant departments to develop biodiesel suitable for marine and boiler use, and further expand the application space of" ditch oil "for biodiesel.
