In the refinery in Bilecik, 45 thousand tons of base oil are produced annually from waste oils

Bilecik’s refinery, located in the Osmaneli district, processes 60 thousand tons of waste mineral oil annually, resulting in 45 thousand tons of base oil which is reintroduced into use through environmentally friendly methods.

The facility processes waste mineral oils collected from various industrial sites across Turkey, authorized service centers, and motor oil change stations through 10 transfer points and transports them to the facility located on an area of 105 thousand square meters by road and railway.

In the refinery laboratory, after analyzing their chemical structure, oils suitable for recycling are used to produce the “group 2” type of base oil, the raw material for lubricating products.

Through environmentally friendly methods, 45 thousand tons of base oil are produced annually from 60 thousand tons of waste mineral oil, and sold to some motor oil companies in Turkey. The product is also exported to certain Middle Eastern and European countries.

TAYRAŞ Base Oil Refinery Inc. Director Ertuğrul Kılıç told AA news agency that the facility began operating in 2021.

Stating that they have an annual capacity of processing 60 thousand tons of waste oil, Kılıç provided the following information:

“We refine waste mineral oils with the world’s most environmentally friendly and advanced technologies to obtain high-quality group 2 base oil. We are the sole producer of base oils in this class in Turkey. Base oils are a significant import item for our country, with annual imports around 700 thousand tons. Therefore, our production also contributes to closing the current account deficit caused by imports.”

“Our facility operates on a ‘zero waste’ principle,” Kılıç said, explaining that they separate by-products from waste oils using distillation, and obtain a material called “asphalt residue” used in insulation.

Kılıç also mentioned that they convert intermediate products from the same process into group 2 base oil through a high-pressure and high-temperature hydro-processing method.

“Our facility operates on a ‘zero waste’ principle. We use environmentally friendly technologies. All the products within the waste oils are valuable. We use the by-products as fuel in our facility,” Kılıç said.

Kılıç noted that they produce high-quality, process, heat transfer, and hydraulic oils from the base oil they sell.

Highlighting that they minimize their carbon footprint by using low energy during the production process, Kılıç stated that they contribute to the environment.

Kılıç stated that the lifespan of base oil is “unlimited” and that it can be reprocessed and re-evaluated by processing, “In this way, we include waste oils in the circular economy. The motor oils obtained from the base oil we sell come back to us as waste oil. We can talk about an endless cycle here,” he said.

Bilecik Şeyh Edebali University Zero Waste Coordinator Prof. Dr. Edip Avşar said that various oils are used to reduce friction in the mechanical systems of motor vehicles, and they eventually become waste.

Avşar pointed out that 1 liter of waste oil pollutes 800 thousand tons of water, evaluating that “This facility prevents environmental pollution to some extent by recycling waste oils.”
