Process engineers face challenges in downstream processing due to larger biomanufacturing scales. A new method evaluates alternative bioseparation technologies, finding none currently viable to replace chromatography for large-scale manufacturing.
Area of Science:
- Biotechnology
- Chemical Engineering
- Process Development
Background:
- Increasing scale and product titers in cell culture processes strain downstream processing capacity.
- Packed-bed chromatography faces capacity limitations, driving the search for alternative bioseparation techniques.
- Evaluating numerous alternative technologies with varying strengths and limitations is challenging for process engineers.
Purpose of the Study:
- To present a methodology for assessing the industrial attractiveness of bioseparation technologies.
- To compare alternative bioseparation techniques against packed-bed chromatography as a reference.
- To identify promising alternatives for large-scale biomanufacturing.
Main Methods:
- Utilized a multiattribute decision making (MADM) analysis approach.
- Incorporated both quantitative and qualitative data for technology assessment.
- Included packed-bed chromatography as a benchmark for comparison.
Main Results:
- The MADM analysis evaluated the trade-offs between the strengths and weaknesses of various bioseparation alternatives.
- While most alternatives showed advantages over packed-bed chromatography, none were deemed overall industrially attractive for current large-scale manufacturing.
- The methodology provided quantitative insights into areas needing improvement for each alternative technology.
Conclusions:
- No current alternative bioseparation technology is a viable replacement for packed-bed chromatography in large-scale manufacturing.
- The developed MADM methodology can guide further technological development by highlighting key improvement areas.
- This approach aids process engineers in selecting and developing suitable bioseparation technologies for industrial applications.
