Biomass is one of
the main types of renewable energy sources (Manzano-Agugliaro
et al., 2013). In addition to producing energy, it contributes to
local economic growth and overall sustainable development (Long
et al., 2013). On the other hand, the biomass residues would appear
to be an interesting source of renewable energy (Callejon-Ferre
et al., 2011). In Spain biomass, wind and hydropower are the
main sources of renewable energy (Montoya et al., 2014).
