Resumen de: WO2025079065A1

A method and system produce fertilizer products by growing cyanobacteria in a photobioreactor, the cyanobacteria performing nitrogen fixation using Nitrogen from the ambient air brought into the photobioreactor. The grown cyanobacteria is harvested from the photobioreactor as biomass, which is subject to anaerobic digestion in an anaerobic digestion reactor, to produce Ammonium, which is optionally subjected to nitrification, in a nitrification bioreactor, to produce the resultant fertilizer product.
