Why Sunresin capturing Global SIRs China battery refining production leadership?



Global solvent impregnated resins (SIRs) market size was valued at USD 453.2 million in 2025. The market is projected to grow from USD 482.7 million in 2026 to USD 732.8 million by 2034, exhibiting a compound annual growth rate (CAGR) of 5.4% during the forecast period. As industries worldwide pursue advanced separation technologies for critical material recovery, these solid-phase extraction materials present unique capabilities for selectively recovering valuable metals from complex aqueous solutions.


Solvent impregnated resins are advanced solid-phase extraction materials that combine the high selectivity of liquid-liquid extraction with the operational simplicity of ion-exchange resins. They are created by immobilizing a liquid extractant within the porous structure of a polymer resin. These materials are crucial for the selective separation and recovery of specific metal ions and other solutes from complex aqueous solutions, with major applications in battery materials recovery and refining, hydrometallurgy, and wastewater treatment. Their development supports the global transition toward circular economies and sustainable resource management.

Market Overview & Regional Analysis


Asia-Pacific holds a dominant position in the global Solvent Impregnated Resins market, with China and Japan being the key drivers. This leadership is largely attributed to the region's massive and rapidly expanding battery manufacturing sector, which is a primary consumer of SIRs for materials recovery and refining. The strong presence of electronics and automotive industries, coupled with significant government investments in EV infrastructure, fuels demand. The region benefits from a well-established chemical manufacturing base and intense competition among local and international players.


North America represents a mature and technologically advanced market, with the United States as the central hub driven by stringent environmental regulations and a strong focus on battery recycling. Europe is characterized by strict regulatory frameworks like the EU's Battery Directive, emphasizing recycling efficiency and material recovery. While South America and the Middle East & Africa present emerging opportunities tied to mining and water treatment, their markets remain smaller in scale and development.



Key Market Drivers and Opportunities


The market thrives on three powerful trends: rising demand for effective and selective separation technologies, stringent environmental regulations and sustainability goals, and advancements in resin matrix materials. SIRs offer a solid-phase extraction method combining high selectivity with operational simplicity, leading to increased adoption for metal recovery in mining and battery recycling. Their ability to minimize volatile organic solvents reduces environmental contamination risk, aligning with corporate sustainability initiatives.


The innovation pipeline includes expansion into pharmaceutical and biotechnology sectors, where high selectivity makes SIRs ideal for purifying active pharmaceutical ingredients and separating complex biological molecules. Development for critical material recovery from electronic waste and mining tailings supports circular economy goals, gaining traction as governments invest in recycling technologies. Ongoing R&D focused on next-generation resins with improved solvent retention, higher thermal stability, and magnetic properties opens new markets for extreme condition applications.



Challenges & Restraints


High initial costs and complex synthesis remain a primary challenge, with production requiring specialized knowledge of polymer chemistry and solvent properties, leading to higher costs compared to conventional ion-exchange resins. For many SMEs, the significant initial investment can be a barrier to adoption despite long-term savings. Furthermore, solvent leaching and limited lifespan—where impregnated solvent can leach out under harsh conditions—reduces resin effectiveness and necessitates frequent replacement, impacting process economics.


Limited awareness and technical expertise gap among potential end-users delays adoption, as companies may lack in-house knowledge to integrate SIRs effectively. Economic sensitivity of end-use industries like mining and chemicals means capital expenditure on new technologies is often deferred during downturns. Competition from well-established separation methods like liquid-liquid extraction requires demonstrating clear advantages for industry switching.
