Resumo: | This work established the unit energy cost generated from biomass of eucalyptus (Eucalyptus sp.) and elephant grass (Pennisetum sp.) and applied a sensitivity analysis to verify the infl uences of factors such as the silviculture of eucalyptus, production volume of each species, the cost of land and the interest rate. It was shown that the treatment of eucalyptus in very short rotation of 2 years with reform of stand every 6 years has a average cost of production higher than the traditional treatment of short rotation of 6 years with reform only at the age of 18. It was also observed that eucalyptus has a Production Cost on average of R$ 4,41 /Gj, lower than the elephant grass which is on average of R$ 5,44/Gj, which however has a higher annual capacity of dry matter production. The elephant grass has the possibility to compete with eucalyptus when a set of conditions is met: discount rate higher than or equal to 8%, High price of land, and elephant grass high volume production, greater than or equal to 35 tonnes of dry matter per hectare and year. |
