Due to the unsatisfactory sales path, most of the biodiesel plants in the country are on the way to stop production. The waste oil recovered by the waste oil recovery enterprises in this background has accumulated due to the lack of buyers.
In 2014, institutional research showed that the amount of waste oil produced in China in 2014 was about 50 million tons, of which only 4% was used for industrial production applications. Most of the resources are unclear through illegal means, or enter the edible oil processing plant, or return to the table to enter the consumer mouth.
The use of waste oil resources alone has highlighted the shortcomings of China at this level. Every year, relying solely on relevant documents to restrict the illegal recovery of waste oil, the effect is minimal. Food safety is as big as it is. Deep resource utilization of waste oil, extending and increasing its value chain can be described as a key path to solve the problem of waste oil. We may as well understand some of the successful experiences of some countries in the world on waste oil recovery.
Food waste disposers and grease separation devices are installed in restaurants and home kitchens in New Zealand. Government-designated companies are responsible for collecting and disposing of used waste oil.
Germany is recycled by professional companies. Every bucket of water has an “ID card†that can be inspected at any time in order to track the destination of waste oil and prevent waste oil from falling into the hands of illegal traders.
The United States requires that the waste oil recovery company must have a legal license, impose heavy penalties for illegal recycling, and strictly regulate the edible oil manufacturing process.
The United Kingdom has set up a waste oil trash can for the uniform recovery of waste oil and then made biodiesel. Restaurants will be heavily fined for falling into the water.
The Japanese government uses high-priced recycled waste oil as fuel, and waste cooking oil produced by restaurants and food processing companies is classified as industrial waste.
In China, despite the government's statement that the development of the biodiesel industry is currently the most effective way to solve the problem of “ditch oil†returning to the table, the situation is not optimistic.
For a long time, due to lack of supply, unsatisfactory sales channels, and difficult industrial policies, many abandoned oil companies have long faced the problem of “not enough to eatâ€, and a large number of biodiesel plants are forced to stop production due to market pressure. Although the biodiesel production industry, which is the main channel for the utilization of waste oil, has been developed for more than ten years, it is still difficult to implement.
The return of the waste oil to the table is an illegal and irrational use of its value. Although some departments have set up special departments to recycle waste oil, in the face of the high profits of the black market to recycle waste oil, traders often see fortunes.
In the face of the only legal biodiesel recycling method, but in the current situation of policy bearish and sales stagnation, enterprises have stopped working, resulting in the accumulation of waste oil due to the lack of buyers, the waste oil manufacturers spend time and effort, but no market can be sold. .
At present, China's waste oil has been developed in energy treatment technology, not only can produce high quality biodiesel and aviation kerosene, but also the production cost is effectively reduced. However, in terms of increasing control and preventing the return of waste oil to the table and promoting the development of the comprehensive utilization of waste oil, the state should reflect its policies and introduce industry standards and corresponding fiscal and tax subsidies as soon as possible to help enterprises bring the biodiesel to the market. Promote the process of resource utilization of waste oil. Among them, the most desirable "policy spring wind" is that the country can boost the use of biodiesel after the pilot, which will bring billions of market opportunities to the biodiesel industry.
Only the bio-diesel with excellent quality and high quality will be fully promoted, and the waste oil will be turned into waste. The waste oil in the kitchen will be completely recovered and transported to the oleochemical enterprise for treatment, and finally turned into biodiesel, which can effectively eliminate the waste oil. Into the residents' table, the comprehensive utilization of the waste oil can rise to a new height.
