Traditional preparative-scale chromatography remains one of the most resource-intensive steps in downstream processing, driven by high solvent consumption, solid waste generation, and limited recyclability. As regulatory and economic pressure increases, sustainability is no longer a secondary consideration but a core requirement for modern chemical and pharmaceutical manufacturing.
This white paper explores Centrifugal Partition Chromatography (CPC) as a solid-support-free alternative that aligns chromatographic performance with green chemistry principles. By eliminating silica-based stationary phases and enabling flexible, recyclable solvent systems, CPC offers a pathway toward lower environmental impact without compromising purity, yield, or throughput.
Beyond separation itself, the paper examines how CPC integrates into broader downstream workflows—from solvent recycling and bioreactor coupling to waste valorization—demonstrating how sustainable chromatography can actively improve process efficiency, reduce costs, and unlock value from low-grade or waste streams.
