Hankook has announced its third ISCC PLUS achievement. The company previously received certification for its Geumsan plant in 2021 and its Rácalmás plant in Hungary in 2023.
At the Daejeon plant, Hankook replaced fossil-based synthetic rubber with bio-circular polymers, reducing the environmental footprint throughout the entire lifecycle, from raw material sourcing to product manufacturing, compared with conventional fossil-based materials. This achievement means the plant has met the stringent certification criteria of ISCC PLUS.
With the certification of the Daejeon plant, Hankook now has a sustainable product manufacturing system spanning original equipment and replacement tires as well as motorsports.
Hankook is actively pursuing open innovation with global partners to further advance sustainable material substitution technologies. In 2025, the company has been promoting technical collaborations with Rotoboost to develop turquoise hydrogen-based carbon black and with Solvay to develop circular silica. Furthermore, Hankook is actively participating in government-funded national research projects and domestic consortia to validate carbon-reduction technologies and expand the commercial viability of alternative materials.
