Integrating microalgae growth in biomethane plants: Process design, modelling, and cost evaluation.

ABSTRACT: The integration of microalgae cultivation in anaerobic digestion (AD) plants can take advantage of relevant nutrients (ammonium and ortho-phosphate) and CO₂ loads. The proposed scheme of microalgae integration in existing biogas plants aims at producing approximately 250 t·y^-1 of microalgal biomass, targeting the biostimulants market that is currently under rapid expansion. A full-scale biorefinery was designed to treat 50 kt·y^-1 of raw liquid digestate from AD and 0.45 kt·y^-1 of CO₂ from biogas upgrading, and 0.40 kt·y^-1 of sugar-rich solid by-products from a local confectionery industry. An innovative three-stage cultivation process was designed, modelled, and verified, including: i) microalgae inoculation in tubular PBRs
