Boeing and rival Brazilian plane-maker Embraer have teamed up to boost the aviation biofuel industry.
Boeing said the plane-building competitors would perform joint biofuel research, as well as fund and co-ordinate research with Brazilian universities and other institutions.
The research will focus on technology to plug gaps in a supply chain for sustainable aviation biofuel in Brazil, such as feedstock production and processing technologies.
Brazil is one of the world's leading ethanol producers with the fuel from sugar cane introduced into its vehicle fleet widely since the 1970s. The joint venture is the latest in about 30 aviation biofuel initiatives around the world.
While there have been test flights using blends of biofuels and jet fuel, they have not been introduced on a wide scale. Feedstock includes used cooking oil, alga, jatropha and sugar cane with most projects in the research or feasibility stages.
