Reactor design for production of fermentable sugars from empty fruit bunch

Bioethanol is a fuel produced from sugar fermentation process that used bio-based renewable sources as feedstock. As the second largest producer of oil palm, Malaysia has abundant of empty fruit bunch (EFB) waste. Despite of tremendous experimental studies done on effectiveness of using EFB for prod...
