Polymers, which have significantly contributed to the improvement of human living standards, have recently been concerned from an environmental point of view such as global warming, waste, and sustainability. SK geo centric is shifting from a traditional petrochemical company to a Green Company leading Waste & Carbon Zero through the establishment of a plastic circulation economy, and to achieve this, we are expanding eco-friendly products and developing plastic recycling technologies. The expansion of eco-friendly products includes the provision of 3R solutions (Reduce, Replace, Recycle) based on the development of high-functional materials and the input of eco-friendly raw materials (Renewable Naphtha) into the petrochemical processes. Recycle is the most pivotal factor in increase of the size of the plastic circular economy and transformation of waste to resource, thus we are establishing a recycle solution platform, consisting of a solvent extraction (PP), depolymerization (PET), and pyrolysis (multi-component materials) as well as mechanical recycle.
