Why is bioethanol production from lignocellulosic biomass generally more expensive compared to production from sugarcane?
- 1It involves direct combustion processes instead of biological fermentation.
- 2Lignocellulosic feedstocks inherently have extremely low total carbohydrate content.
- 3Pre-treatment processes required to break down complex plant cell walls into fermentable sugars are highly costly.✓
- 4It requires genetically modified yeast for basic alcohol fermentation.
