Ethanol Usage in Urban Public Transportation - Presentation of Results 2010-36-0130
The usage of ethanol in buses is a reality in cities from Sweden, such as Stockholm. The technology of diesel bus adapted to operate with ethanol has been used in that country since 1985, with great success, mainly in the environmental point of view. With the intent of encouraging ethanol usage in urban public transportation aiming, among other goals, at the reduction of atmospheric pollution in the big urban centers, the BEST Project - BioEthanol for Sustainable Transport was created. Besides Sao Paulo (pioneer in the Americas), this project, encouraged by the European Union, counts with eight other cities located in Europe and Asia. In Brazil, the project was developed and coordinated by CENBIO - Brazilian Reference Center on Biomass, from the Electrotechnics and Energy Institute of USP. With the partnership of other institutions, the project is developed since 2007 and currently counts on two diesel buses adapted to operate with ethanol. The buses circulate in operatives from EMTU - Sao Paulo Metropolitan Company for Urban Transports, in the Jabaquara - Sao Mateus line, and in operative from SPTrans - Sao Paulo Transportations, in the Lapa - Vila Mariana corridor. This paper has as its purpose to present the BEST Project in Brazil, its partners and, mainly, the results from the demonstration tests performed in field, as well as the proposals of public policies that were elaborated and are being implemented. It is worth remembering that the technology of the buses pays attention to the EURO 5 strict emission Standards, a norm that was recently invigorated in Europe.
