Abstract
Anaerobic digestion (AD) is a well-established technology for the treatment and stabilization of high-strength wastes and wastewaters. Biogas production is the major driving force of the growth in AD industry. However, the industry is challenged by digestate management problems based on stricter regulations coming into force, large volumes of digestate, and potential environmental pollution concerns. Treatment opportunities developed so far are yet to be a common practice depending on the fact that land application is still a preferred option for its handling. Digestate treatment using microalgal cultures is a promising approach due to valorization potential from the biomass obtained in terms of bioproducts and biofuels. The studies conducted up to now clarify that microalgal treatment processes have certain limitations regarding operational, techno-economic, and environmental perspectives to overcome for large-scale applicability. This chapter provides information on treatment potential of digestates by microalgal cultures with a specific emphasis on challenges and potential remedies.
