Refining waste oil into diesel or base oil is a resource recycling technology with significant environmental and economic benefits. With the continuous growth of global energy demand and increasingly stringent environmental regulations, waste oil recycling technology has become an important part of the sustainable development strategy.
1. Environmental benefits: Alleviating ecological pressure
① Reduce pollution sources
If waste engine oil, lubricating oil, etc. are discharged directly without treatment, 1 liter can pollute 1 million liters of fresh water. Through refining technology, more than 90% of toxic substances such as heavy metals (lead, cadmium) and polycyclic aromatic hydrocarbons in waste oil can be removed, greatly reducing the risk of soil and groundwater pollution. EU research shows that the pollutant emissions of recycled oil products are 50%-70% lower than those of original crude oil refining.
② Carbon emission reduction advantages
According to the International Energy Agency, each ton of recycled diesel can reduce CO₂ emissions by 2.8 tons compared to fossil diesel. The energy consumption of the refining process is only 1/3 of that of crude oil refining, which meets the emission reduction requirements of the Paris Agreement. The US Environmental Protection Agency has certified that the carbon footprint of recycled base oil is 80% lower than that of mineral base oil.
2. Economic Benefits: Creating Circular Value
① Significant cost advantage
The procurement cost of waste oil raw materials is only 20%-30% of the crude oil price. Taking a refinery with an annual processing capacity of 50,000 tons as an example, it can produce 38,000 tons of diesel (based on a 75% yield). According to the current oil price, the annual gross profit can reach 120 million yuan, and the investment recovery period is about 3-5 years.
② Output quality
Diesel (can reach Euro IV-Euro VI)
Base oil (can reach SN150-SN500)
The practice of the Chinese company FUOOTECH shows that refining waste oil can increase the value of waste oil by 4-6 times.
3. Energy security: Supplementing the supply gap
① Reduce import dependence
China produces about 8 million tons of waste oil each year. If all of it is recycled, it can replace 5% of diesel imports. Germany has passed the "Circular Economy Law" to promote the waste oil recycling rate to 92%, reducing crude oil imports by 1.5 million tons per year.
② Ensure emergency supply
Recycled oil products can be used as a supplement to strategic reserves. During the 2022 Russia-Ukraine conflict, Poland reduced the diesel market supply gap by 18% by increasing waste oil recycling capacity.
4. Social Benefits: Promote Green Employment
① Create New Jobs
Every 10,000 tons of waste oil treatment capacity can create 15-20 technical jobs. The UK recycled oil industry has absorbed 12,000 employees and contributed 800 million pounds to GDP annually.
② Promote technological innovation
Modern refining technologies such as molecular distillation and hydrofining have made continuous breakthroughs, and the annual growth rate of related patents in China during the "14th Five-Year Plan" period reached 25%. Sinopec (Yangzi) Waste Oil Regeneration Project won the 2023 International Circular Economy Innovation Award.
FS-HDM Series Waste Oil Distillation • Re-refining Turnkey Plant
Diesel (can reach Euro IV-Euro VI)
Base oil (can reach SN150-SN500)
FUOOTECH Group combined with Fangsheng is the top manufacturer of waste oil distillation & re-refining plant. Our plant can distillate & re-refine waste engine oil, crude oil, waste gear oil, waste crankcase oil, waste hydraulic oil, tyre pyrolysis oil, plastic pyrolysis oil, automotive used oils, marine used oils, industrial used oils, and other wastes fluids to diesel oil or base oil with widest possible range of diesel oils ranging from Euro IV to Euro VI depending upon the raw fluids. Such plants have been exported to more than 40 countries and regions, and the 90% of orders are complete turnkey project.
In 2023, the 6th-generation waste oil regenerative distillation re-refining plant successfully developed by our company aims to increase the oil yields upto 90% and ensure the whole operation without any risks and danger. It was perfectly combined with the most advanced Series WYLJ Anaerobic Pyrolysis Separation carbonization System for waste oil sludge which was developed at the same year, helps the waste oil regeneration ratio increased upto 99.9% max.
(Note: Other company's products only produce the around 70% of oils), therefore, our plant can bring more benefits to customers.
It is very suitable for large and small repair shops, various general machinery, ships, trucks and other heavy pollution (that is, dirty oil and mixed oil that cannot be treated by chemical methods).
