Study Notes
Monoclonal Antibody Production
- A life-cycle analysis of a monoclonal antibody (mAb) produced by fed-batch cell culture was conducted, comparing conventional stainless steel and single-use technologies.
- Single-use technologies have a lower environmental burden across different scales.
Water and Steam Requirements
- The stainless steel plant requires a significant amount of water and steam for cleaning and sterilization operations.
- These requirements outweigh the solid waste disposal needs of single-use technologies.
Cell Culture Processes
- Fed-batch processes have less environmental impact than perfusion processes, which consume more water.
Viral Inactivation
- The detergent Triton X-100 has been widely used for viral inactivation, but it can degrade to an endocrine-disrupting alkylphenol after discharge.
- An alternative detergent, LDAO (lauryldimethylamine-N-oxide), is much less ecotoxic and just as effective at inactivating viruses.
Sustainability in Biopharmaceutical Manufacture
- Much more work is needed to evaluate the impact of biopharmaceutical manufacture from a sustainability viewpoint.
