During the past few years, use of disposable bioreactors in development and manufacturing processes has become widely accepted. Particularly, low–oxygen-demanding cell types such as human and insect cells have proven to be perfectly suitable for cultivation in single-use bag chambers. These bioreactors have significant advantages over their reusable counterparts (1). They transform a single-purpose process using stainless steel reactors into a multipurpose facility in which switching from one application to another is both easy and cost effective. Reusable…

Environmental Life-Cycle Assessment of Disposable Bioreactors
Disposable technology for bioprocessing is efficient and cost effective in many product development scenarios. For an industry dedicated to improving human health, however, the environmental contributions of a product must also influence its bottom line. Product transitions evaluated within a people/planet/profit framework require assessment regarding shifts in human and environmental impact. Life-cycle assessment (LCA) offers one perspective by evaluating the environmental loading of inputs and outputs to a product or process. The contribution of individual product life-cycle stages…
Integration Is the Future of Single-Use Technology
Single-use technologies are becoming more widely accepted by biopharmaceutical manufacturers than ever before. The market is complex, fast-growing, and dynamic, which means integrated innovative technologies are the key to keeping pace with biopharmaceutical manufacturing needs. In fact, end users are already beginning to move away from singular disposable components to increasingly require suppliers to provide integrated solutions for specific process needs. So it is critical for suppliers to work closely with their customers and provide novel solutions. Why the Switch?…
Scaling Up a CHO-Produced Hormone–Protein Fusion Product
Many biotechnology companies recognize the powerful benefits of increasing product titer early in product development as a strategy to minimize manufacturing costs, scale, and the duration necessary to produce clinical supplies and achieve product commercialization. Additional benefits include minimizing or completely avoiding significant regulatory delays to market that can be caused by major process technology changes (such as cell line and product quality changes). Recently, another significant benefit has been realized too: Smaller, more productive and efficient 2,000-L…
Trends in Single-Use Bioproduction
Most people in the biopharmaceutical industry recognize, at least anecdotally, that the use of disposables in biomanufacturing is moving forward. At BioPlan Associates, we’ve tried to quantify how things are advancing and capture some of the shifts in attitudes, especially in light of current economic challenges. The major shift is that decisions are being made more from an operational point of view. It’s become less a question of if disposables will be implemented than of where and how.…
