LE MACROALGHE COME BIORISANATORI E LORO APPPLICAZIONI IN ECONOMIA CIRCOLARE: IL PROGETTO REMEDIALIFE

Abstract

Here we report the results of the REMEDIA Life Project concerning macroalgae cultivated in an integrated multitrophic aquaculture (IMTA) system realized in the Gulf of Taranto (Italy). The species Chaetomorpha linum (O.F. Müller) Kützing and Gracilaria bursa-pastoris (S.G. Gmelin) P.C. Silva were considered. Their bioremediation capability was evaluated as well as their potential exploitation since large amounts of macroalgae were obtained which represent a co-product of bioremediation opening new markets in relation to their high commercial value and in the light of a circular economy in line with the "Blue Growth". Macroalgal biomass could be used to create biotechnological products, including innovative feed (to be supplied directly on the farm during fish farming), fertilizers and bioactive compounds with antioxidant and antibacterial action, useful in the pharmaceutical and nutraceutical fields. Finally, macroalgae could be used in the field of human nutrition as a delicious and healthy "novel food".
