2500+ hours of Operation 2600+ tonnes ethanol produced

Started up all three trains (6 bioreactors + inoculator) All unit operations running

(gas clean up, fermenters, distillation, WWT, biomass recovery)

Train turnaround: <48 hours 85% of total production rate 50% direct water recycle

Optimization in progress Multiple lessons learned
