obtained from the extraction of the oil, which still have a potential for its use in
obtaining other products through fermentation processes or chemical synthesis. On
the other hand, these types of processes present a high acidification potential, which
is mainly due to the high energy demand that is presented. For this, it is necessary to
use a large amount of fuel to supply it. During the combustion process to obtain the
required energy, there is a high release of carbon dioxide, which has a negative
impact on the environment by altering the acidity of the air. As a consequence of
this process can cause acid rain among other phenomena caused by the high
concentration of this type of gases in the atmosphere.
8 Energy Production from Microalgae Chlorella
Protothecoides Through the Biorefinery Concept:
A New Proposal
Microalgae present a high potential to be used to obtain different value-added
products, which can lead to a more sustainable production of bioenergy. For this, it
is necessary to apply concepts such as biorefinery (Moncada et al. 2013; Mussatto
et al. 2013). From this concept, it is possible to use the different residues that are
presented in a stand-alone case of biodiesel production in other processes. Among
the products with great potential to be obtained under this concept is energy from
the biomass resulting from the process of lysis. In this same process, it is possible to
obtain both glucose and lipids. The glucose obtained can be used in ethanol production (Quintero and Cardona 2009). Where it can be used in conjunction with
lipids for the biodiesel production. Figure 6 presented this idea.
