Conclusions
It´s necessary to diversify the energy matrix .
The plant´s location is in IX region.
The Biorefinery´s bioethanol production covers 48% of the chilean demand.
NPV = 0 Price bioethanol
1.055 US$/m3 unprofitable
If the price of the enzyme decreases 10 times the proyect is profitable

General Objectives
Explore new technological developments to produce second
generation bioethanol from eucalyptus waste, and an economic
study.
• Raw material availability study
• Study of the process involved in bioethanol´s production and co-
products manufacture.
• Plant location study.
• Conceptual design of Biorefinery plant
• Fixed cost, operation costs and inversion study.
• Economic analysis and sensibility study
