Conclusions
No significant increase in BMP was observed when mixing these
substrates. The kinetic constants of the mixture 25% WAS e 75%
LSBB was much higher than for WAS, LSBB and Glycerol alone.
Moreover, the mixture 10% Glycerol e 90% LSBB did not show a
higher kinetic constant with respect to both substrates separately.
Even though no benefits in term of increase of BMPwas observed as
a result of co-digestion, the increase in kinetic constant of one of
the mixtures, plus the possibility of treatment of different residues
using the same installations, turns co-digestion into an interesting
alternative to provide adequate treatment of lipid-spend microalgae
