CONCLUSIONS 1. Pyrolytic gases recirculation in the fast pyrolysis fluidized bed facility as na additional source of energy to the process and fine charcoal applications are important ways to increase the process sustentability and avoid the production of high quantity of losses. 2. Energy yield in the bio-oil production is acceptable considering that its LHV is about 55 % of the fossil diesel in volume. 3. From the emergetic point of view bio-oil production process is sustainable. Its best application is to replace chemicals from fossil sources.
