Research indicates that around 85% of the energy demand in antibody manufacturing is attributed to the facility's infrastructure, including HVAC systems, lighting, and utilities. Specifically, HVAC systems alone account for nearly half of the total energy use, with lighting contributing significantly as well. This suggests that optimizing plant operations and layout may be as crucial as enhancing production technologies.
Conducted by Benjamin Smith, PhD, and colleagues, the study modeled three different manufacturing scenarios: stainless-steel fed-batch, single-use fed-batch, and continuous processing. The analysis revealed that while continuous processing utilized a smaller bioreactor, it achieved comparable outputs with a reduced facility footprint, leading to lower energy intensity. The findings underscored that the physical size of the facility is a critical factor in determining energy efficiency.
Moreover, the study explored the potential for further improvements through enhanced continuous processes and facility upgrades. By optimizing various factors such as cleanroom classifications and airflow, researchers found that energy consumption could be reduced by about 35%. These insights suggest that rethinking facility design and operations could significantly contribute to greener biomanufacturing practices, emphasizing the importance of an integrated approach to sustainability in the life sciences sector.
