DEEP PURPLE (Domestic extraction of emerging products with purple phototrophic bacteria)

A project financed by the Public-Private Association Bio-Based Industries (BBI JV), led by AQUALIA and in which FCC Medio Ambiente also participates together with: Activatec, RNB, Natureplast, Instituto Tecnológico del Embalaje, Transporte y Logística (ITENE), Brunel University London, Novamont, Universidad Rey Juan Carlos, Alchemia-Nova, Asociación Española de Normalización (UNE), Gate2Growth, Universidad de Valladolid (UVA) and Centre Mondial de l’Innovation – Roullier.

The DEEP PURPLE concept


This is a pilot research project on applying the most innovative techniques across the board in managing the different effluents generated in the organic waste treatment facility (digestate, leachate and biogas), based on the Circular Economy principles promoted by the European Union. It uses purple phototropic bacteria to recover by-products in wastewater, such as polyhydroxyalkanoates and hydrogen, single cells, or nitrogen and phosphorus for their use as fertilisers.

FCC Medio Ambiente is actively involved in optimising the Thermal Hydrolysis process to produce a nutrient-rich broth that is used as food for the purple phototrophic bacteria that synthesise PHA, a basic molecule for the production of bioplastics.
