Keysino’s membrane separation technology employs semi-permeable membranes to selectively segregate solutes, offering a sustainable solution for recovering valuable components from industrial waste streams. This method effectively extracts residual APIs from spent mother liquors, minimizing environmental contamination while enhancing resource circularity. With advantages including low energy consumption, operational simplicity, and compact system design, Keysino’s process supports scalable implementation across production phases. By integrating membrane-based recovery, the company enables manufacturers to achieve dual objectives: reducing waste discharge and reclaiming high-value materials, aligning industrial efficiency with ecological stewardship in pharmaceutical operations.
