Turn waste into treasure's "sewer oil" to change "diesel"

As one of the hot topics nowadays, people mention the “oil waste” change. Everyone pays more attention to the harm caused by the catering industry. As everyone knows, it can also turn waste into treasure, transform into new energy, and contribute to humanity.

Sounds like this is good news, or it will be one of the new ways to ease the energy crisis.

Xiao Bian found relevant information and found that there are so many applications of waste oil:

Drain oil can produce biodiesel

Waste oil can produce biodiesel through a slightly acidic catalyst technology and a metal salt treatment agent, greatly reducing the production cost of biodiesel production.


Biodiesel

Some companies have already discovered this business opportunity. For example: “Jiangsu Clean Environment Technology”, Jiangsu Clean Environment Technology Co., Ltd. extracted biodiesel methyl ester, liquid organic fertilizer and biogas from waste oil. Harmless treatment can achieve 100% utilization of resources.

The company has already attracted the attention of Royal Dutch Airlines. Since the cost of biofuels extracted in this way is lower than that of biofuels extracted from conventional sources, the company’s 200 flights will use Suzhou Waste Vegetable Oil Recovery Co., Ltd. from the trenches. Bio-oil extracted from oil.

Preparation of beneficiation agent with "ditch oil"


Mineralizer

The teachers of the Department of Environmental Engineering at Beijing University of Science and Technology have innovatively proposed a technology for the preparation of beneficiation agents using “ditch oil”. First, the impurities in the “ditch oil” are removed through pretreatment methods to prepare fatty acids or fatty acid sodium. The by-product glycerol obtained is also an important chemical raw material and satisfactory experimental results have been obtained. If waste oil can be used for the preparation of fatty acid collectors, the dual effects of pollution reduction and comprehensive utilization can be achieved.

"Irrigation oil" changes to ethanol, biogas and diesel




Ethanol

Researchers at the Institute of Plasma Physics of the Chinese Academy of Sciences, using food and kitchen waste to produce ethanol and biogas, have turned the food waste into four “babies,” namely biodiesel, ethanol, biogas, and biofertilizer.

It is understood that the biggest feature of this technology is that its energy-based thinking is different from the domestic feed-based technical route, to avoid food waste entering the human food chain once again, resulting in homologous accumulation of disease risk.

Policy favors the conversion of new energy technologies from waste oil

According to Xinhua News Agency, in order to facilitate tax collection and management, the Ministry of Finance and the State Administration of Taxation have issued a notice a few days ago to clarify the use of animal and vegetable oils to produce pure biodiesel exempted from the use of consumption tax.

The two ministries made it clear that the scope of the “Discarded Animal and Vegetable Oils” mentioned in the “Notice of the State Administration of Taxation of the Ministry of Finance on the Use of Waste Animal and Vegetable Oils for the Exemption of Consumption Tax on Pure Biodiesel” includes catering, food processing units and households that do not allow Edible animal and vegetable fats and oils. It mainly includes swill oil, fried waste oil, waste oil, and range hood condensate.

Regarding this tax exemption policy, related industry sources said that this is a positive signal, which means that the country recognizes that the economic and technical feasibility of biodiesel is very strong. It will have a price competitiveness in the future before it will be given before industrialization. State subsidies.
