The oil, that is, the lubricating oil of the engine, can lubricate, clean, cool, seal, reduce, rust, and prevent the engine.

After a long period of use, the oil will produce deposits, sludge, and paint film, which will cause deterioration. These substances are deposited on the surface of the friction member, the passage of the lubricating oil, and the filter, which may cause various malfunctions of the machine.

With the continuous advancement and rapid development of China’s industry, the holdings of various construction machinery, vehicles and ships are getting higher and higher, and the demand for oil is increasing. The waste engine oil is also known for its huge output, and each year. In order to dispose of it, recklessly dump it or incinerate it. This is not only a problem of large-scale environmental pollution, but more importantly, it involves the energy crisis that is constantly spurred by China. Therefore, the treatment of waste lubricating oil is a major issue worthy of attention. So how should we properly dispose of used engine oil?

Where did the waste oil go?

According to estimates, at present, China’s various types of construction machinery and equipment, automobiles, ships and aircraft trains and other large-scale machinery produce between 25 million to 30 million tons of waste engine oil. In fact, these waste lubricating oils are treated by appropriate processes to remove metamorphic components and foreign impurities. Contaminants can be recycled lubricants. This method is a suitable treatment method from the perspective of technology, environmental protection, rational use of resources and economics. However, according to statistics from relevant departments, the current recycling rate of used motor oil is only 20%. So where did these waste oils go?

1, Discard

After the replacement of used engine oil, the economic value is extremely low, which has always been in the status of “waste”. For a small amount of waste oil, people often pay less attention to it and pour them into rivers, wild open spaces or garbage cans. This approach can cause significant pollution to the environment and waste resources.

2, Incineration

At present, the use of waste engine oil as a fuel is also a common treatment method. Many construction sites will mix waste engine oil with other construction wastes that need to be incinerated, and burn them to destroy these buildings. These waste oils can produce good combustion-supporting effects. This treatment is also very harmful to the environment, although the government has repeatedly Stop, but a lot of illegal builders are doing this in order to save trouble.

3, Recycling

In recent years, waste oil recycling technology has begun to spread to the private sector. Many waste oil distillation plant, large and small, have begun to appear in the market. They will personally go to the construction site to recycle these waste oils, and then transport them to the refinery to manufacture these waste oils. Poor waste oils are fueled by “refurbishment” methods such as distillation, cooling, bleaching, etc., and then blended with regular national standard oil in a ratio of one-third or even one-half, which is the source of inferior diesel. The better quality waste engine oil is treated by appropriate process to remove metamorphic components and foreign impurity contaminants into recycled lubricating oil, and then flows through the packaging to the oil market. Although this method has always been a reasonable approach in all respects, most small vendors do not have precise control and strict requirements in the production process and production methods, and the quality of the produced oil does not meet the standards. This is also the reason for the proliferation of various fake brand-name engine oils on the market.

4, Road access oilization

The waste oil is sprayed on the road which is easy to dust, and the dust is adhered by the adhesive action, which is dustproof and is also a treatment method of the waste lubricating oil. In the United States, a significant portion of the recovered waste lubricating oil is used for this purpose. However, the waste oil sprayed on the road will also be washed by rainwater into the drainage ditch when it rains, and finally enter the river to pollute the water, or enter the soil to pollute the soil, thus polluting the environment.
How to dispose of used motor oil properly?

Waste motor oil not only has its second life, but also is used in daily life. For the waste oil with a large output, it can be stored in a container and then sold to a regular refinery for secondary use.

It is undoubtedly the most appropriate way to recycle the replaced waste lubricating oil, which not only can make full use of resources, but also bring considerable economic benefits and avoid environmental pollution caused by random disposal.

In addition to those illegal private refineries, there are nationally recognized regular refineries in all regions of the country. These manufacturers can recycle the processed oils to meet national standards, and the oils they extract can be assured to users. purchase. If these waste oils flow into the hands of unscrupulous traders, it will greatly disrupt the oil market, and it is still our own. The unit engaged in the recycling of used engine oil must be the holder of the solid waste management hazardous waste business license.

For the waste oil with a small output, it is also used in a lot, the magical effect of waste engine oil.

1. Waste oil can be used to lubricate the chain.

Waste motor oil can still lubricate the parts where the lubricating oil is not required. For example, some bicycle metal hinges such as our bicycle chain, excavator, loader and other equipment can be applied with waste engine oil. To lubrication, anti-friction, anti-rust effect.

2. At the construction site, the waste engine oil can be used on the building formwork to prevent the formwork and cement from sticking together, and also to prevent rust and corrosion.

3. The use of diesel oil refined from waste engine oil for vehicles may damage the fuel system of the vehicle, but it is not a problem for the stoves used by catering companies or some machinery factories. Moreover, the price of fuel refined with waste engine oil is much cheaper than that of gas on the market. Some catering companies and machinery factories are also willing to use this fuel oil.

The survival and civilization of mankind, the development and improvement of society, the source of its power has been closely dependent on oil, but the limited resources are increasingly exhausted, and the proper and effective treatment of these waste oils has far-reaching and important significance for us.
