Integrating microalgae into the Brazilian program for biodiesel production and use

Brazil's programme for production and use of biodiesel is a novel program, aimed at improving the sustainability of biodiesel by promoting social inclusion, whilst simultaneously increasing food security, diversifying feedstocks and producing a lower carbon fuel. The aims of the program have been evaluated by conducting a qualitative ana-lysis of the system. The existing system is then compared with the introduction of microalgae as a feedstock. This research shows that revisions to the program are needed in order to address economic, social and environmental sustainability. Particular attention must be given to more thorough environmental criteria for land use and agricultural techniques. Family farmers need stronger support in order for biodiesel to become a sustainable product for them to grow. Microalgae could be included into a biodiesel program, provided sufficient incentives are given, and this could improve the overall sustainability of biodiesel production and use.
