LC Biorefinery : Most difficult to master Challenges and Opportunities :

• Developing economically viable grinding, pre-treatment and saccharification processes for releasing the sugar • Most efficient industrial scale pre-treatment process for releasing the sugars and sufficiently flexible for a variety of biomass resources • Low cost enzymes for the hydrolysis • An efficient co-fermenting microbes or catalytic process for sugar conversion • Option to separate C5 and C6 sugars

. Integrating all the process chains designed to reduce production costs

. Demonstration of all the technological advances on a large scale Technology Evolution via Breakthroughs!
