Resumo
Brazil is the largest sugarcane producer in the world, an important
input to ethanol production, which puts the country in a privileged
position in biofuel world market. Besides the importance of sugar
production in the sugarcane chain, this work focuses on ethanol
production (ethanol industry), particularly its main waste, vinasse.
Vinasse presents several environmental risks due to its bio composition
and, if dumped in rivers or lakes, causes the phenomenon of
eutrophication, which promotes a high growth of aquatic plant species
and spread environmental problems. In this scenario, the anaerobic
digestion of vinasse (the most abundant effl uent from a sugarcane
biorefi nery) arises as an interesting alternative because, in addition to
promoting the stabilization of organic matter, it also enables energy
generation from biogas (biomethane). Anaerobic digestion generates
biomethane and biofertilizer from vinasse. The objective of this article
is to study the biogas potential generation from sugarcane vinasse
in Brazil using anaerobic digestion technology also presenting the
challenges and the governmental agenda required to develop biogas
systems to sugarcane sector in Brazil. This work presented a huge
biogas production potential from sugarcane vinasse. It can be used in
multiple ways, and this work emphasized two important energy uses:
to substitute natural gas and to generate electricity in a distributed
generation concept. Besides the huge potential, there is an extensive
agenda to solve and overcome the multiple barriers for biogas systems
implementation in Brazil. According to international experience the
strong governmental involvement is necessary and suffi cient condition
to develop renewable energy sources. In that sense, biogas systems
need to be inserted in Brazil’s policy agenda
