STAR Refinery at a Glance

As the largest single-point investment by the real sector in Türkiye, we meet approximately 19.5% of the country’s need for processed petroleum products.

Thanks to our integrated Petkim structure, fast conversion capability, and state-of-the-art technology, we can process various types of oil efficiently. Our annual crude oil processing capacity of 12 million cubic meters enables us to produce petroleum products such as diesel, jet fuel, naphtha, and LPG.

Thanks to our operational flexibility, we don't know any limitations when it comes to refining. We add value to the national economy through our rich product portfolio, and we work harder every day to ensure steady and safe production. In 2021, while we were in the top third of the list of ‘Türkiye’s 500 largest Industrial Enterprises 2021’, we have been placed at the top in the list of ‘Aegean’s largest Industrial Enterprises’.
