Domestic Recycling Infrastructure and Its Role in South Korea’s PET Flake Supply

The South Korea recycled PET (rPET) flakes market, valued at USD 439.59 million in 2024, is projected to grow at a CAGR of 8.1% from 2025 to 2034, with national policy impact, R&D leadership, and strategic positioning shaping the trajectory of both domestic and global players. While South Korea is a mid-sized market in absolute terms, its influence extends beyond its borders due to its advanced recycling infrastructure, stringent regulatory framework, and role as a technology leader in Northeast Asia. The country’s performance is increasingly benchmarked against global leaders such as Germany, the United States, and China, each of which brings distinct advantages in local manufacturing bases, innovation hubs, and trade policy design.

South Korea’s national policy impact is evident in its comprehensive waste management system, which achieves a PET bottle recycling rate of over 80%, among the highest globally. The EPR system, administered by the Korea Environment Corporation, ensures consistent funding and accountability across the value chain. This policy stability has enabled long-term investment in recycling infrastructure, particularly in food-grade purification facilities. The government also supports R&D leadership through grants from the Ministry of Trade, Industry and Energy (MOTIE) for projects in chemical recycling and digital sorting. Innovation hubs such as the Ulsan National Institute of Science and Technology (UNIST) and the Korea Institute of Science and Technology (KIST) are collaborating with industry on next-generation decontamination technologies and biocatalytic depolymerization.

Germany remains the global leader in circular economy policy and rPET demand, with mandatory recycled content laws and a highly efficient dual system (DSD) for waste collection. German firms such as ALBA Group and APK AG are pioneers in chemical recycling, setting technical benchmarks that South Korean companies are actively studying and adapting. The U.S., while lagging in national policy impact, is advancing through state-level initiatives and corporate leadership, with companies like Indorama Ventures and Loop Industries investing in advanced recycling plants. China, despite its ban on plastic waste imports, is expanding domestic rPET capacity, driven by national self-sufficiency goals and rising environmental awareness.

Corporate strategies among top South Korean players reflect a focus on market share concentration and strategic positioning. Lotte Chemical and SK Geo Centric have vertically integrated into recycling to secure feedstock for their polyester production, reducing reliance on virgin materials and enhancing ESG performance. These firms are also expanding overseas, with SK investing in rPET facilities in Southeast Asia to serve global supply chains. Hanwha Solutions is leveraging its chemical expertise to pilot methanolysis plants, positioning itself at the forefront of chemical recycling. Meanwhile, Woongjin and Sejong Recycling are forming joint ventures with Japanese and European partners to access premium markets and comply with international food safety standards.

The future of the rPET market will be defined by how effectively countries and companies align their R&D leadership, regulatory frameworks, and commercial strategies to meet the growing demand for sustainable materials.
