Sustainability
We pave the way for sustainability-driven innovation with our tire technology designed to define the future of our planet.


E.Circle Process
We remain committed to a sustainable environment from the initial process of designing tires to identifying the hazards of chemical substances used for our products throughout the planning, manufacturing,
and disposal processes.


Four approaches of E.Circle
As the global economy continues to grow, demand for goods is also increasing gradually. However, we must prevent resource exhaustion through efficient use as the resources given are not infinite.
Sustainable Resources and Materials Strategy and Goal
Our constant research spans the following four principles: recycling, renewable, reusable, reducing.
-
Recycle
We reprocess waste tires to obtain the recycled rubber or the reinforcing filler, and use resources efficiently by replacing the petroleum-based raw materials with the recycled ones.
-
Renewable
To contribute to resource conservation, we are actively discovering renewable raw materials and continuously developing technologies that apply them to our production.
-
Reuse
Retreading tire technology, which converts the old tires in a good structural condition into new ones by covering them with rubber, we contribute to the environmental preservation by significantly reducing the amount of raw materials used.
-
Reduce
We reduce the CO2 emissions with use of renewable energy and saving resources as well as the resource consumption by prolonging the use period while extending the lifespan of products.
Our Sustainable Materials at a Glance
Mid- to long-term research designed to use green and sustainable bio-based raw materials and recycle tires


Use of Sustainable Materials
Hankook Tire realizes the eco-design that reduces negative impact on the environment by discovering and applying the eco-friendly materials to reduce the environmental impact of tire use and raw material acquisition. With active use of sustainable materials, we are achieving our result in preventing any depletion of natural resources and reducing CO2 emissions.
Discovering Sustainable Materials and Developing Applied Technology
Hankook Tire is researching various sustainable materials and developing application technologies to reduce the CO2 emission in raw material acquisition stage on cradle-to-gate. As part of these effort, Hankook receives global eco-friendly international certification “ISCC PLUS”, first among tire manufacturers. The ISCC PLUS certification is a great solution in this regard because the certification allows the system a transparent, traceable management for use of sustainable materials. This in turn allows us to reduce the CO2 emissions, prevent the depletion of resources, and expand the use of sustainable materials.

Developing Sustainable Tires
Hankook Tire is conducting various R&D activities to prevent resource depletion and reduce carbon emissions from the product development stage, where the environmental impact of tires is determined the most. In 2022, we succeeded in developing tires containing 45% of sustainable materials, satisfying both the legal requirements for passenger car tires and the requirements of demanding automakers. In addition, tires containing 55% of sustainable materials are developed successfully, and their durability is being evaluated in harsh conditions. Both tires contain sustainable raw materials such as ISCC PLUS certified synthetic rubber, recycled PET cord, recycled carbon black, bio-based silica, oil and resin. We will continue to conduct our research and development to use 100% sustainable materials for all tires by 2050.
Technology Collaboration of Eco-friendly Tire
Hankook Tire is conducting joint R&D of sustainable tires with some automakers to lead eco-friendly mobility. Recently, we obtained technical approval for sustainable tires for the electric vehicle through a joint project with a premium European automaker. This tire is scheduled to receive ISCC PLUS certification for the first time in the world among tires supplied to finished vehicles. Compared to conventional tires (Based on 1,000 units), sustainable tires have the effect of reducing carbon dioxide by approximately 7,000 kg CO2eq, which is equivalent to the annual absorption of approximately 1,400 trees. Going forward, we plan to promote the active technology development and global collaboration with the goal of 100% sustainable tires.
