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

Question & Comment

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
