Revalorization of solid waste microalgae biomass from pig manure water treatment towards fertilizers production

Abstract

This work aims at implementing the biorefinery concept by valorizing the microalgae biomass produced from pig manure wastewater treatment as a substrate for biogas production through anaerobic digestion. Furthermore, several pretreatments are applied to improve the CH 4 methane production. The obtained digestate solid is used in a new subsequent revalorization for fertilizer production.
