South Korea Scrubbers System Market Overview, 2031

Market Insights on South Korea Scrubbers System Market

• According to the research report, "South Korea Scrubbers System Market Overview, 2031," published by Bonafide Research, the South Korea Scrubbers System market is anticipated to add USD 64.69 Million by 2026–31. The South Korean scrubbers system market operates within one of Asia's most rigorously enforced environmental regulatory frameworks, anchored by the Ministry of Environment (MOE) and the foundational Clean Air Conservation Act, which sets permissible emission levels of air pollutants from air pollutant-emitting facilities through a concentration-based regulatory approach. Over the past five years, this market has been fundamentally reshaped by the convergence of domestic emission control mandates and international maritime regulations.
• The IMO 2020 sulphur cap, reducing permissible fuel sulphur from 3.5% to 0.5% globally, has been a primary driver, with the Ministry of Oceans and Fisheries (MOF) establishing South Korean Emission Control Areas (ECAs) and confirming that scrubbers can be used with no restrictions on open-loop scrubber washwater discharge.
• Vessel operators must either install exhaust gas cleaning systems (scrubbers), use clean fuels such as low-sulfur fuel oil, marine gas oil, or LNG. The market serves diverse end-users including power generation, steel manufacturing, cement production, chemical processing, semiconductor fabrication, and waste incineration.
• South Korea's thermal power sector has witnessed significant emission reductions: after the installation of electrostatic precipitators (ESP), FGD, and SCR systems, mercury emissions were reduced by nearly 69% (7.1 tons per year) from coal-fired power plants as a co-benefit of stringent air pollutant controls.
• The Taean Thermal Power Station, one of the world's largest coal-fired power plants, implemented advanced FGD wastewater treatment achieving zero liquid discharge. POSCO, South Korea's leading steelmaker, has successfully mass-produced high-alloy steels essential for SOx scrubber systems, predicting more than 12,000 vessels would apply scrubbers over the next five years. Technological advancements increasingly favor high-efficiency wet limestone-gypsum FGD systems achieving >95% SO₂ removal efficiency.

Competitive Landscape of South Korea Scrubbers System Market

• POSCO has emerged as a critical player, mass-producing high-alloy stainless steel for maritime SOx scrubber systems and tapping rising demand as new IMO regulations take effect. In the maritime segment, Korean shipyards reported a 20-30% increase in scrubber-equipped newbuild contracts from 2024 to 2025.
• LiqTech has partnered with Danbee Marine to market marine scrubber water treatment solutions in South Korea. In the semiconductor sector, plasma scrubbers are a common technology employed in the semiconductor and display industries, which represent a significant market share and are experiencing steady increases in emissions. SK hynix developed new technology elevating greenhouse gas treatment efficiency of scrubbers used in etching processes to 99%.
• Entry barriers remain exceptionally high, driven by capital-intensive installations and rigorous permitting under the Clean Air Conservation Act, which adopts concentration-based regulation for air pollutant-emitting facilities.
• The value chain extends from specialized component suppliers to engineering, procurement, and construction contractors. Consumer behavior among industrial operators has shifted toward integrated multi-pollutant control platforms combining ESP, FGD, and SCR systems. The MOE has implemented emission charges, with nitrogen oxides charged at 2,130 won ($1.90) per kilogram.

South Korea Market Dynamics

Driver: Clean Air Conservation Act and Emission Standards
The Clean Air Conservation Act sets permissible emission levels of air pollutants from air pollutant-emitting facilities through concentration-based regulation. The Act controls eleven key air pollutants including nitrogen oxides (NOₓ), sulfur oxides (SO₂), particulate matter (PM), and volatile organic compounds (VOCs). Emission limit values are defined in Ministry of Environment Ordinance No. 17797.

Challenge: FGD Wastewater Treatment Complexity
FGD wastewater contains high concentrations of contaminants, making it unsuitable for discharge without further processing. The high dissolved solids content makes recycling within power plants difficult. Additional treatment is required to remove minerals and recover water for reuse. The Taean Thermal Power Station implemented a zero liquid discharge system to address these challenges.



Trend: Zero Liquid Discharge FGD Wastewater Treatment
The industry is shifting toward zero liquid discharge systems for FGD wastewater treatment. Aquatech delivered an advanced wastewater treatment system at the Taean Thermal Power Station converting challenging FGD wastewater into high-purity water and mixed salts, achieving zero liquid discharge. This trend reflects tightening Effluent Limitation Guidelines for coal-fired power plants.

Segment Analysis

South Korea Scrubbers System Software Market by Scrubber Type
• Wet Scrubbers represent the dominant technology in South Korean industrial applications, with wet limestone-gypsum FGD being the most widely adopted process. The Dangjin Power Station's wet limestone-gypsum FGD system achieves >95% SO₂ removal efficiency. Wet scrubbers are deployed in power generation, steel manufacturing, chemical processing, and waste incineration facilities. PCDD/DF concentrations at wet scrubber inlets in Korean waste incinerators ranged from 0.2 to 37.4 ng TEQ N m⁻³.
• Dry Scrubbers serve specialized applications where water scarcity or wastewater concerns favor dry sorbent injection systems. MET's licensee won a dry flue gas desulfurization project award in Korea, with the SDA system acting as a polishing scrubber providing 70% removal efficiency. Dry scrubbers are increasingly adopted in cement manufacturing and waste incineration applications.
• Biological Scrubbers and Electrostatic Wet Scrubbers address specialized applications in semiconductor, chemical, and food processing sectors. Plasma scrubbers are a common technology in semiconductor and display industries. Wet electrostatic precipitators are designed to treat exhaust gases from POU scrubber outlets and final FAB exhaust. ENVEX offers high-efficiency hybrid systems combining scrubbers and precipitators.

South Korea Scrubbers System Software Market by Application
• Gaseous/Chemical Cleaning applications dominate the South Korean market, driven by the need to remove SO₂, HCl, HF, and acid gases from industrial exhaust.
