Mind the Gap: Managing Relationships Between Upstream and Downstream Intensification

Process intensification (PI) describes an integrated framework of strategies to maximize the output of a unit operation, a process, or an entire facility. By implementing PI strategies, biomanufacturers can accomplish their productivity goals by increasing production speeds and titers, reducing facility footprints, and cutting costs. Overall, such changes improve production efficiency and flexibility. Collectively, the biotherapeutic industry has made multiple advancements in intensifying upstream processing. PI strategies include using high-density cell banks, implementing seed-train intensification (n – 1 perfusion), and…

A Strategic Approach to Selecting the Optimal Process Intensification Scenario

Current demands placed on the biopharmaceutical industry are pushing manufacturers toward process intensification, an approach that modifies unit operations or an entire manufacturing process to optimize efficiency. Three common intensification scenarios in upstream processing are seed-train intensification (usually at the n – 1 stage), concentrated fed-batch production, and dynamic perfusion (at the production bioreactor stage). In downstream processes, intensification strategies typically involve moving from single- to multicolumn chromatography. Biomanufacturers can realize several kinds of improvements from intensified processing, including reductions…
