During the last decades the search for new alternative and
renewable energy resources has increased rapidly, as a response to
the increase in population that caused growing energy demand for
transportation and industry and a huge consumption of limited
fossil fuels. Dramatic raises in oil prices and global warming
reached threatening limits. Hence, there has been a tremendous
urge in extending the use of biofuels and biomass derived energy,
since it can be obtained from sustainable resources [1]. Biomass,
which refers to living and recently dead biological materials, is an
infinite and renewable feedstock for production of biofuels [2].
However, in order to become a future alternative fuel source some
properties are required. First of all, the potential candidate must
decrease greenhouse gas emissions, decrease energy consumption,
slow down global warming by capturing and storing CO2 and
provide efficient energy utilization. Furthermore, its production
technology must be clean with regard to the environment and be
economically feasible [3]. Besides, non-food feedstocks can also be
used in the production of alternative fuels in order to prevent some
concerns and ethical problems related to their usage. Bioethanol
proved itself as an attractive low-cost alternative to replace fossil
fuels with its biorenewable nature carrying all of the features
required.
