The aim of this paper is to present the BEST project —
BioEthanol for Sustainable Transport, developed by CENBIO — Brazilian Reference
Center on Biomass in Brazil. It’s an European Union initiative and coordinated
by the Stockholm mayor, that aims to promote the ethanol usage, replacing diesel,
in the urban public transport in Brazil and worldwide. Apart from Sao Paulo,
leading city in the Americas, another eight cities located in Europe and Asia
take part in the project: Stockholm (Sweden), Madrid and Basque Country (Spain),
Rotterdam (Holland), La Spezia (Italy), Somerset (England), Nanyang (China) and
Dublin (Ireland). One of the Brazilian project’s goals is to evaluate ethanol
usage as diesel fuel replacement in public transport buses by comparatively
following the operational output of the experimental fleet (fuel consumption,
performance and occurred failures), taking as reference an equivalent diesel bus.
The utilized test vehicles will be evaluated and monitored to demonstrate
ethanol energetic efficiency and after the results the BEST project and the
European Union will set a blue print for public policies to incentive ethanol
usage in the urban public transport. The results will allow identifying
technical and economical barriers that will eventually overlap the viability
process of this technology in the Brazilian public transport. This paper will
put forward the technology developed by the Swedish Scania, available and
technically improved, that adapted the diesel engine to operate with ethanol,
agreements in place in the search for partners, the body and engine import
procedures, as well as the imported additive that will be added to the ethanol
and the one year period tests methodology that will start in December 2007. The
time is very favorable to the Brazilian program, as it is an alternative to
diminish the metropolitan region pollution where the technology will be
demonstrated, reducing up to 90 % of particle material emissions and 62 % of
nitrogen oxides launched in the atmosphere, apart from not emitting sulfur
responsible for the acid rain. The vehicle will reduce in up to 80 % gases
emissions responsible for global warming. The engine utilized in the tests is
well advanced even for European pollution standards, as it respects severe
specifications like EURO 5 and EEV (Enhanced Environmentally Friendly Vehicles),
norms that will be compulsory in the European Union from 2009 onwards. This
technology usage is a great achievement, as the Brazilian law accepts the EURO 3
emission standards. It is expected that this competitive advantage and the BEST
project development in Sao Paulo will attract the attention of other places in
Brazil for this technology. Another favorable point is the fact that diesel
costs almost double the price of ethanol in Brazil that is the second biggest
ethanol producer in the world (18 billions of tons in 2007 and expecting 38
billions of tons by 2012), apart from the upward trend in the petrol cost.
