Resumo:

In the experts panel the technology drivers were discussed considering the three pillars set beforehand for jet biofuel production within this roadmap: a) reduce production costs, b) ensure that biofuels are environmentally sustainable, and c) that biofuel production improves rural development. The main technology drivers, summarized in Table 19 to Table 22, are presented individually and distributed according to the critical system requirements. Only drivers explicitly mentioned in the workshop by the speakers are presented below.For plant feedstocks, genetic improvement and crop management practices were the main technological to meet most critical systems requirements. The technology drivers varied according to group of plants or specific crops, because crops are in different stages of technological development and cultivation in Brazil. Sugarcane, soybeans and eucalyptus are widely cultivated and have strong R&D bases, but jatropha and camelina are relatively new crops in Brazil. For instance, for jatropha, detoxification of residues, and mechanized harvest were considered important drivers to reduce feedstock prices. Different aspects or problems were emphasized by the experts assembled in different groups. However, it seems clear that most improvements can be obtained with research in areas such as plant breeding and agricultural practices. The use of modern technologies such as molecular biology and precision agriculture can speed up progress.
