Summary in the original language of the document

To explore alternatives to mineral fertilizers, a pilot facility producing fertilizer from Adriatic fish and mollusk sidestreams was developed. It involves different production stages: the mechanical treatment of raw materials, a subsequent hydrolysis and a concentration step (Figure 1). A life cycle assessment (LCA) identified the main environmental hotspots of this fertilizer production regarding climate change, acidification and eutrophication: production of enzymes for hydrolysis, energy use during the concentration step and packaging.


Summary translation

Um Alternativen zu Mineraldüngern zu erforschen, wurde eine Pilotanlage zur Herstellung von Düngern aus Fisch- und Muschelabfällen aus der Adria entwickelt. Sie umfasst folgende Produktionsstufen: die mechanische Behandlung der Abfälle, eine anschliessende Hydrolyse und einen Konzentrationsschritt (Abbildung 1). Im Rahmen einer Ökobilanz wurden die wichtigsten ökologischen Hotspots der Recyclingdünger-Produktion im Hinblick auf den Klimawandel, die Versauerung und Eutrophierung ermittelt. Dies sind die Herstellung der Enzyme für die Hydrolyse, der Energieverbrauch während des Konzentrationsschritts und die Verpackung.
