PTU Overview

"PTU" stands for Pretreated Unit or Pretreated Used Cooking Oil, and refers to preprocessing refined or preprocessed products for using animal/vegetable fats and oils as raw materials for HVO (Hydro-treating), one of the types of SAF (Sustainable Aviation Fuel).

* SAF type: HVO (Hydro-treated Vegetable Oil) AtZ (Alcohol to Jet). E-Fuel and BtL (Biomass to Liquid)

PTU is a pretreatment production concept that removes the negative factors of hydrogenation during HVO production, such as Chlorides, Metals, Impurities, and Water, in ppm to trace.

Status of Introducing SAF Mandatory Blending System

- Status of Introducing SAF Mandatory Blending System in Major Countries (Mandatory Blending Rate)

*ASIA

※ When using 1% of Korea's SAF, carbon emissions is reduced by 160,000 tons (based on 20 million tons of international aviation carbon emissions)

   Status of Introducing SAF Mandatory Blending System

Production Facilities and Distribution Activities

• Gain competitiveness by developing PTU production facilities with low cost and high efficiency.
• Secure diversification and supply capabilities through continuous development of independent technology and infrastructure.
    - Constructed the PTU production facilities at Ulsan Shinhang Plant
    - Achieved the first overseas export in Korea with PTU produced with unique and independent technologies in 2024
