The value of used engine oil

When we talk about engine oil, we are referring to the lubricant of the engine. The main role of the oil is to lubricate the engine to reduce wear, auxiliary cooling and cooling, sealing and leakage prevention, rust and corrosion prevention, shock absorption and buffering. Construction machinery needs to change the oil diligently to ensure the healthy operation of the equipment.

Waste oil:

One refers to the oil in use mixed with water, dust, other tramp oil and metal powder and other impurities generated by the wear of the machine parts, resulting in dark color and increased viscosity.

The second refers to the gradual deterioration of engine oil, which generates organic acids, gums and asphalt-like substances.

With the development of the economy, the construction of the country prompted a variety of the vehicles, ships and engineering machinery and equipment ownership has increased greatly. It is understood that China’s vehicles, ships, aircraft rockets and engineering machinery and equipment can produce an estimated 30 million tons of waste oil each year. How is the waste oil usually treated?

At present, incineration of used oil is also a common way of treatment. Many construction sites mix used motor oil with construction waste that needs to be incinerated and incinerate it to destroy it, which is also very harmful to the environment.

Another common way of disposal is to discard, especially the small amount of used oil that is replaced is often not taken seriously and is dumped directly into garbage cans, vacant lots and even ditches and rivers after replacement. This method is not only a waste of resources, but also causes great pollution to the environment. It is not advisable to discard used motor oil, which may be mixed with water and endanger human health if it seeps into the soil or flows into rivers.

In foreign countries, recycled used oil is often used to spray on dusty roads, using its adhesive effect to stick the dust to achieve the purpose of dust control. However, even if the used engine oil is sprayed on the road, when it rains, the used engine oil is very easy to be washed into the drainage ditch by the rain, and finally enter the river to pollute the water or seep into the soil, so it will also pollute the environment.

In fact, these waste lubricating oil after appropriate process treatment, remove deteriorated components and foreign impurities and pollutants can become recycled lubricating oil, this method is a suitable treatment method no matter from technical, environmental protection, rational use of resources and economic perspective. But many small traders’ production process and production method cannot do the control and strict requirements, and the quality of the produced oil does not meet the standard, which is exactly the reason for the proliferation of various fake engine oils on the market.

Undoubtedly, recycling the used lubricating oil that is replaced is the right way to go. This will not only make full use of resources, but also avoid environmental pollution caused by random disposal.

In a word, the larger amount of used oil can be stored in containers and sold to regular oil refiners for secondary use.
