If you can read in Portuguese – the Biodiesel BR is a good place to get news about biodiesel developments in Brazil. Unfortunately, it is quiet expensive to access the full site but for free you can read the 1st paragraph or two of their articles. The good news is that most of the information is already in the public domain, so if you find something interesting – it is easy enough to google and find further information elsewhere without having to pay their hefty fees.
They are currently promoting a Conference in Brazil on Biodiesel – unfortunately, there is not yet a full list of speakers or any real conference information. I’ve never been to one of these before – would be keen to hear from anyone who has attended.
Here is the conference link:
