The rapid expansion of the global automobile industry has significantly increased the demand for tail gas purification technologies. Alongside this, new and stricter emission regulations across various sectors—such as the chemical industry—have created a growing need for advanced environmental catalysts. Recognizing this opportunity, forward-thinking catalyst manufacturers have entered the environmental protection catalyst market, seeing it as a lucrative sector with strong growth potential.
Developed regions like the EU, Japan, and the U.S., along with emerging markets in Latin America and Asia, are expected to drive the demand for these catalysts. As a result, major players in the environmental catalyst industry are actively competing to capture market share. Several leading companies have already expanded their operations into China, signaling a shift in global manufacturing and innovation strategies.
According to SRI Consulting, the global environmental protection catalyst market is currently valued at around $5 billion and is projected to grow at an annual rate of 4.5% to 5%. A significant portion of this market—about 90%—is dominated by automotive exhaust gas purification catalysts, while the remaining 10% comes from industrial gas catalytic purification. Leading companies such as Engelhard and Johnson Matthey (JM) hold substantial shares, each capturing around 35%, followed by Umicore with approximately 20%. The rest of the market is shared among smaller players like Catalytics Solutions (CSI), Delphi Catalysts, and Southern Chemicals.
Engelhard, the largest supplier of automotive catalysts, is expanding its production capacity globally. Last year, the company upgraded its facilities in Shanghai, and also established an engine testing lab in Germany and an R&D center in China. Its latest innovations include diesel oxidation catalysts designed to meet strict emissions standards while reducing the use of palladium, a costly metal.
Meanwhile, JM reported a significant increase in sales of diesel automotive catalysts in Europe during the first half of the year. The company recently expanded its production in Shanghai and opened a new plant in Japan, expecting higher sales in the coming years. JM is also focusing on heavy-duty diesel catalysts and is involved in emission control systems for chemical plants. In particular, there is a rising need in China and other countries for catalyst technology that can manage halogenated hydrocarbon emissions from by-products of purified terephthalic acid, a technology already adopted in India, Iran, and Pakistan.
Umicore, another key player in the environmental catalyst industry, believes that the strong growth of the Chinese auto market will boost demand for automotive catalysts across Asia. To capitalize on this, the company has invested 20 million euros in a new production facility in Suzhou, which is now operational.
Catalytics Solutions (CSI) has emerged as one of the top three environmental catalyst manufacturers. Its proprietary MPC (Multi-Point Catalyst) system offers a cost-effective solution by significantly reducing the use of platinum group metals. Utilizing nanotechnology, the system is durable, economical, and versatile. CSI has already partnered with major automakers like Ford, General Motors, and Honda to implement this technology.
Southern German Chemical Company is also advancing its environmental catalyst offerings. In February 2004, it acquired coating technology for diesel exhaust catalytic purification from Wacker Chemie and integrated it into its energy and environmental division. The company is now collaborating with automotive manufacturers to bring this innovative coating technology to market quickly.
