Recovery of nutrients from the OFMSW is a relevant topic as evidenced by the European initiative \”End of Waste\”. Following this guideline, the Ecoparc 2 of Montcada i Reixac, belonging to the Metropolitan Area of Barcelona, submits the OFMSW to anaerobic digestion and then the digestate is separated mechanically, fisrt by pressing and then by centrifugation. The solid of press (Sp) and the solid of centrifugue (Sc) are com- posted together (CSp+Sc) and used as organic fertilizer. There are alternatives to the current treatment of the OFMSW as: (1) direct use of Sc as fertilizer, (2) composting of Sc (CSc) and (3) composting of Sp (CSp). This paper focuses on analyzing the recovery of nutrients
