Abstract—Anaerobic digestion (AD) of algae biomass has
been investigated since long. However to enhance full scale
commercial future prospects of algal bio technology, it is
important to develop methods for better utilisation of the algae
biomass. For effective AD involving algae biomass, there is still a
need for intensifying algae biomass digestion. Pre-treatment
practices on micro and macro algae improve the digestibility of
the algae biomass and an increase in biogas yield. Co-digestion
of algae biomass with BWW, sewage sludge and agricultural
waste is a promising sustainable strategy as it enhances AD and
helps in the safe disposal of different wastes. Combining
pre-treatment and co-digestion provides a better practice of the
AD process. Utilisation of AD of algae biomass, and the potential
of AD of algae biomass with three co-digestion feedstock
–Sewage sludge, spent grain and agricultural waste are further
discussed. This paper concludes that AD can act as a better
‘connecting link’ in the algae bio technology providing economic
viability and sustainable practice.
