How to deal with waste oil recycling? What is the use value?

Engine oil, that is, engine lubricating oil, can play the role of lubrication, cleaning, cooling, sealing, anti-wear, anti-rust and anti-corrosion of the engine. For construction machinery and equipment, oil is equivalent to human blood and is closely related to the health of the entire equipment. As we all know, once the human blood deteriorates, it will produce pathological changes, which will lead to various diseases and even threaten our lives. After long-term use, the oil will produce sediment, sludge, paint film, and cause deterioration. These substances are deposited on the surfaces of the friction parts. Lubricating oil passages and filters can also cause various malfunctions of the machine. The difference is that human blood can be constantly regenerated and kept fresh and pure. For construction machinery, often change the oil to ensure the healthy operation of the equipment. Waste oil refers to the waste lubricating oil replaced from various construction machinery, vehicles and ships.

With the continuous progress and rapid development of China's industry, the number of various construction machinery, vehicles and ships is increasing, and the demand for oil is also increasing. Waste oil is also known for its huge production. Every year, in order to dispose of it, regardless of the consequences, it is dumped or burned. This is not only a large-scale environmental pollution problem, but more importantly, it involves the energy crisis caused by China. Therefore, the treatment of waste lubricating oil is a major concern. So how should we properly deal with waste oil?

It is estimated that at present, China's various construction machinery equipment, automobiles, ships, aircraft and trains and other large machinery produce 25 million to 30 million tons of waste oil per year. In fact, these waste lubricants can be converted into renewable lubricants after proper process treatment to remove spoiled components and foreign impurities and pollutants. This method is a suitable treatment method from the point of view of technology, environmental protection, rational use of resources and economy. However, according to the statistics of relevant departments, the current recovery rate of waste oil is only 20%, so where is the waste oil?

After the waste oil is recycled, it has been in a "waste" state due to its low economic value. People usually pay little attention to small amounts of waste oil and dump it in rivers, open spaces or garbage bins. This will cause serious pollution to the environment and resources. Studies have shown that a bucket (200L) of waste oil poured into water can pollute 3.5 square kilometers of vast water surface. More seriously, lubricating oils contain 3,4-benzo (PAH) and other polycyclic aromatic hydrocarbons (mainly found in mineral base oils), which have been shown to have a strong carcinogenic effect; chlorinated polycyclic aromatic compounds, such as polychlorinated biphenyls (PCBs), are also substances that are strongly toxic to humans; heavy metal salt additives contained in lubricating oils and organic substances such as extreme pressure anti-wear agents containing chlorine, sulfur and phosphorus are harmful to humans and organisms. These substances mixed into the water may be harmful to human health through various channels.

At present, the use of waste oil recovery as fuel is also a common treatment method. Many construction sites mix waste oil with other construction waste that needs to be incinerated, incinerate and destroy the buildings. These waste oils can produce a good combustion-supporting effect, and this treatment method is also very harmful to the environment. Despite repeated blocking, many illegal builders still do so in secret to avoid trouble.
