Discussion • Hotspot Breakdown: Buffer preparation (36%), fermentation (21%) and medium preparation (21%) consume most resources through the three levels • Electricity (50%) (mainly for HVAC) and chemicals and nutrients (35%) are the categories that represent the highest resource consumption

Lessons Learned/Best Practices •
Highest contribution to fossil/electricity consumption: HVAC is the +-20 times air recycling/h (depending on GMP area) necessary? ISPE Belgian Affiliate & GSK & UGENT; reducing by 30-40% almost reduces cumulative E consumption by 30% (HVAC major hotspot)
•
Continuous freeze drying and continuous downstream chromatography IN-LINE in development Process Intensification
•
Both SM and LM API production have a high burden when it comes to fossil fuels, however SM; Chemical SC LM: HVAC!

Research Outlook
Research Outlook • Substantial knowledge creation on environmental impact of API LM synthesis processes • Disposables vs single use equipment vs stainless steel equipment? • Need to move downstream in supply chain: what about distribution networks? Logistics? Use phase? Waste management? • Take into account other impacts as well (‘Human Health’, EU PEF impact categories)
