South Korea Pyrolysis Oil Market size is projected at USD 20.68 million in 2026 and is expected to hit USD 46.57 million by 2034 with a CAGR of 10.65%. The industry is moving from demonstration-scale chemical recycling toward commercial integration with refineries and petrochemical crackers, supported by waste-plastic circularity programs and investment in advanced thermal conversion. Market assessment increasingly requires feedstock-level data, process economics, end-fuel applications, technology adoption, and competitive positioning to quantify commercial opportunities through 2034.
Pyrolysis oil is a liquid hydrocarbon-rich product obtained through thermal decomposition of plastic, rubber, biomass and other carbonaceous feedstocks in an oxygen-limited environment. In 2026, plastic contributes USD 8.83 million, or 42.7%, of the supplied feedstock-based total, followed by rubber at USD 5.45 million and 26.4%, biomass at USD 4.09 million and 19.8%, and others at USD 2.31 million and 11.2%. Fast pyrolysis accounts for about 58.3% of the process-based total. Industrial adoption is being reinforced by domestic facilities: LG Chem has completed a supercritical pyrolysis facility with 20,000 tons/year capacity, while LOTTE Chemical's reported demonstration-scale pyrolysis operation processes approximately 1,500 tons/year of PE and PP.

Technology is shifting from conventional batch thermal treatment toward continuous, supercritical and upgraded pyrolysis systems capable of processing contaminated mixed plastics. LG Chem's supercritical process targets 20,000 tons/year and can convert approximately 80% of incoming plastic into renewable oil, with the remaining roughly 20% available as process gas. The facility is designed around difficult-to-recycle streams that mechanical recycling cannot efficiently handle.
Petrochemical integration is simultaneously expanding downstream demand. LOTTE Chemical has commercialized petrochemical products using pyrolysis-oil-derived naphtha and previously outlined a pathway toward approximately 150,000 tons of pyrolysis-related business by 2030. LG Chem reported using 6,593 tons of post-consumer recycled raw materials during 2024, around 360 times its 2020 level, illustrating broader adoption of circular feedstocks alongside chemical recycling.
South Korea's petrochemical industry is investing in technologies capable of converting difficult waste streams into refinery-compatible feedstocks. LG Chem's facility has 20,000 tons/year capacity and its technology can achieve more than 80% conversion of plastic waste to renewable oil, while approximately 20% by-product gas can support facility energy requirements. Separately, the proposed Ulsan ARC was designed for around 320,000 tons/year of plastic recycling, equivalent to roughly 9% of the approximately 3.5 million tons of Korean waste plastic reportedly incinerated or landfilled annually.
Commercial plants face high capital requirements, variable waste composition and additional upgrading costs needed to meet petrochemical specifications. SK Geo Centric's Ulsan ARC was originally associated with approximately KRW 1.8 trillion of investment and a 215,000 m² site, but construction plans were subsequently postponed amid petrochemical-sector weakness and investment reassessment. The originally planned pyrolysis component targeted 66,000 tons/year, demonstrating both the scale potential and financial exposure involved in moving from pilot projects to industrial facilities.
Mixed PE, PP, films and contaminated packaging create a sizable addressable feedstock pool beyond mechanical recycling. LG Chem's process indicates that 10 tons of plastic waste can generate approximately 8 tons of pyrolysis oil and 2 tons of gas, equivalent to an oil conversion yield near 80%. Korea also generates approximately 50,000 tons of marine waste such as discarded fishing nets annually, providing another potential circular feedstock stream. Integrating such resources with certified petrochemical production can increase recycled content while reducing dependence on virgin fossil naphtha.
The principal challenge is producing standardized output from heterogeneous waste while sustaining plant utilization and competitive economics. Planned commercial projects range from LG Chem's 20,000-ton/year facility to SK Geo Centric and Plastic Energy's originally proposed 66,000-ton/year Ulsan pyrolysis facility. At the same time, LOTTE Chemical's reported 1,500-ton/year PE/PP pyrolysis operation demonstrates the substantial scale-up required between pilot and large commercial systems. Project postponements additionally show that financing, petrochemical margins and capital allocation can materially influence commercialization timelines.
