BIOJET FUEL IN BRAZIL: TECHNOLOGICAL ROUTES AND FEEDSTOCK AVAILABILITY

摘要

This study aims to evaluate the technical and economic potential for biojet production in Brazil, byidentifying the cost-effectiveness of different technological routes and assessing the competitive opportunities forBrazilian growing market of biojet fuel. To this end, a series of indicators have been developed. Preliminary resultsreveal Brazil may play an important role in the biojet market worldwide. Among different feedstocks, agriculturaland forestry wastes present significant potential of production; however, in spite of its low-cost, the technologicalroutes based on residues have yet to become cost-competitive with conventional fossil fuel production. Additionally,there is a large technical potential of biojet production from oleaginous crops. However, this feedstock is alreadyapplied in biodiesel production, the environmental gains are limited due to the high dependence on fossil fuelresources both at the agricultural and industrial stages and feedstocks are also expensive. The LCA performed in thisstudy revealed important life cycle GHG emissions and fossil fuel consumption reductions, as all the alternative fuelsmodeled revealed reductions of over 70%. However, factors related to infrastructure, taxation and productivity mayconstrain the findings of this study
