Electro-Oxidation Market worth $2.1 billion by 2030, at 6.0%, says MarketsandMarkets™

Delray Beach, FL, Aug. 10, 2025 (GLOBE NEWSWIRE) -- In terms of value, the Electro-Oxidation Market size is projected to grow from USD 1.6 billion in 2025 to USD 2.1 billion by 2030, registering a CAGR of 6.0%, as per the recent study by MarketsandMarkets™. The electro-oxidation industry has emerged in response to increasing demand for sustainable water treatment technologies aimed at addressing global issues like water scarcity and pollution. Stricter government regulations for environmental protection are encouraging industries to adopt more advanced technologies to ensure compliance with discharge standards. Electro-oxidation is a promising method similar to other advanced oxidation techniques that can break down non-degradable or hard-to-degrade pollutants without the need for chemical additives. Rising public health concerns—such as emerging contaminants, pathogens, and risks associated with poly- and perfluorinated compounds, pharmaceuticals, plastics, and heavy metals—are driving the growth of electro-oxidation across various sectors, including industrial manufacturing and municipal water treatment, where access to clean drinking water remains a top priority. Additionally, electro-oxidation offers flexibility by treating water and wastewater from diverse sources, even drinking water. This makes it an attractive option for many industries looking to replace outdated methods with more efficient and sustainable waste management solutions.

Key Findings of the Study:

1. Indirect electro-oxidation is anticipated to be the largest segment in the electro-oxidation market, by type, during the forecast period.
2. Boron-doped diamond is anticipated to be the largest segment in the electro-oxidation market, by electrode material, during the forecast period.
3. Organic and micropollutant treatment is anticipated to be the largest segment in the electro-oxidation market, by application, during the forecast period.
4. The municipal water & wastewater segment is anticipated to be the largest segment in the electro-oxidation market, by end-use industry, during the forecast period.

Indirect electro-oxidation holds the largest share in the electro-oxidation market segments, as it is more efficient than direct electro-oxidation for treating complex, high-load industrial wastewater. In indirect electro-oxidation, pollutants are not oxidized directly at the electrode surface like in direct electro-oxidation. Instead, this method generates strong oxidizing agents—such as active chlorine, hypochlorite, or ozone—in the reaction medium, which help break down refractory organic pollutants and toxic compounds that are usually difficult to eliminate with standard methods. This approach also allows for broader application across industries like textiles, petrochemicals, pharmaceuticals, and dyes, where wastewater often contains high levels of non-biodegradable pollutants. Additionally, indirect electro-oxidation systems tend to operate more stably and have longer lifespans than direct electro-oxidation systems because they are less prone to electrode fouling and corrosion, resulting in lower maintenance costs and extended operational life. These systems also offer operators greater flexibility to function effectively across varying pH levels and conductivity, thus supporting better scalability for municipal and industrial applications.

Boron-doped diamond (BDD) electrodes lead the electro-oxidation market because of their superior electrochemical performance and stability. BDD electrodes provide a wide potential window, very low background current, and a very high overpotential for oxygen evolution. This enables the formation of strong oxidizing species, such as hydroxyl radicals, with minimal side reactions. Hydroxyl radicals can break down many persistent organic pollutants, and BDD has proven especially effective in treating mixed industrial effluents from industries like pharmaceuticals, dyes, petrochemicals, and landfills. BDD electrodes also show excellent chemical and electrochemical stability, easily tolerating highly acidic or alkaline conditions, which allows continuous operation with minimal electrode degradation over time. A major benefit of BDD is the chemically inert nature of its parallel, rather than active, surface where charge transfer occurs. This prevents intermediate species from adsorbing or fouling the electrode, significantly reducing the risk of electrode passivation and maintaining consistent performance. Although BDD electrodes are more expensive than traditional materials like graphite or platinum, their longer lifespan, superior oxidation ability, and lower maintenance costs make them a cost-effective choice for high-demand applications. Additionally, BDD’s ability to achieve nearly complete mineralization of pollutants while complying with environmental discharge standards worldwide makes it highly desirable. For these reasons, BDD electrodes have become the standard and most widely used type in advanced electro-oxidation systems across the industry.

The organic compound & micropollutant treatment has the largest market share, due to the growing demand for advanced oxidation processes that can degrade persistent, complicated, and organic compounds. Practically, all of the industrial effluents from pharmaceuticals, textiles, petrochemicals, and agriculture contain organics that cannot be biologically degraded or removed by physicochemical means. These include dyes, antibiotics, endocrine disruptors, pesticides, etc. Electro-oxidation, especially with conductive diamond electrodes, can generate strong oxidants that will mineralize these persistent compounds into benign end products, the removal of the original compounds is often critical to achieve the required discharge norms, especially when environmental regulations are tightening, as we have seen in places like the EU, China, and the U.S. Micropollutants, even in small amounts, can result in potentially large adverse ecological and health risks. The need to invest in advanced treatment technologies is pressing. Electro-oxidation provides a chemical-free, small footprint technology that can be easily integrated into a polishing treatment stage and is a good fit for reuse applications in municipal and industrial contexts.

Based on end-use industry, municipal water & wastewater captures a large portion of the market for electro-oxidation, as there is strong global demand for advanced tertiary treatment technologies that meet mandated discharge. Municipalities are pressed to eliminate emerging contaminants (such as pharmaceuticals, endocrine-disrupting compounds, and other persistent organic pollutants) that bio and chemical treatment technologies do not efficiently remove from the water. Since electro-oxidation generates hydroxyl radicals and other strong oxidizing agents that degrade non-selectively a wide range of micropollutants without generating by-products that are harmful, electro-oxidation acts as a reliable choice. Because electro-oxidation systems can be retrofitted into existing municipal treatment infrastructure and due to their compact and modular design, electro-oxidation is attractive in the urban water management context. Regulatory compliance is also a powerful driver in the operational case for electro-oxidation, particularly in places like the European Union and parts of Asia, which are imposing strict nutrient loads and micropollutants discharge standards for wastewater facilities. In addition to producing desirable treated water supporting water reuse initiatives in water-scarce regions, municipal facilities benefit from low chemical dosing, low sludge formation, and possible automation from the operation of an electro-oxidation system, making for an ongoing cost-effective option.
