We are a global leader in advanced materials, with expertise in high-purity chemicals, high-performance polymers and electronic materials, driving innovation in the semiconductor industry. In recent years, the demand for semiconductors has been continuously expanding, leading to a significant increase in the usage of chemicals in semiconductor manufacturing processes. Among these chemicals, ultra-high-purity sulfuric acid is widely used in semiconductor cleaning and surface preparation processes due to its strong oxidative and contaminant removal capabilities. 

Recycling technologies for chemicals used in semiconductor processes have been gaining attention to reduce environmental impact and promote efficient resource utilization. Because semiconductor manufacturing requires extremely low levels of metallic, particulate and organic impurities, maintaining sulfuric acid purity during recycling is highly challenging. Conventional recycling approaches face limitations related to impurity removal efficiency and material compatibility, while process-derived contaminants may further impact acid stability. 

By leveraging technologies such as distillation/membrane separation, chemicals can be reused while maintaining ultra-high purity, enabling sustainable manufacturing processes. In the future, advancements in recycling technologies are expected to lead to the adoption of even more efficient systems.
