Abstract
This work provides an evaluating of the life cycle sustainability of biodiesel from soybean in Southern Brazil, one
of Brazil’s most important production regions of biodiesel and soybean. Life cycle approach and Dashboard of
Sustainability (DoS) were applied to identify the hotspots gathering social, environmental and economic dimensions
with the intention to obtain a sustainability factor index (SFI). Primary and secondary data were collected (specific
and generic) covering all biodiesel soybean factories in Southern Brazil. Three environmental impact categories,
three types of costs and four stakeholders were assessed. The results suggest that biodiesel production presented
the most positive contribution to the economic dimension among all stages and that transportation had the worst
value in all sustainability dimensions. In terms of the biodiesel production chain, the most critical impacts were
acidification for environmental, supply costs for economic and the stakeholders’ local community/society (together)
for social. Also, issues associated with energy sources, feedstock improvements and shortening distances are key
factors that could contribute to the overall sustainability of soybean biodiesel chain. There are opportunities for
improving the environmental and economic dimensions together in industrial stage from methanol and electricity.
Also, the social dimension can be upgraded in all life cycle if their actors compromise with social policy. The SFI
presented was in the direction of sustainability, and it is possible to perceive the social dimension with a higher
possibility of improvement. SFI remains similar results throughout of biodiesel chain production. Besides that, the
results can support future strategies associates with energy security policy and social, economic, and environmental
development of biodiesel production chain.
