The LimoFish Circular Economy Process for the Marine Bioeconomy

The outcomes of applying the zero-waste extraction “LimoFish” process based on defatting fish processing waste with limonene to leftovers of European sardine (Sardina pilchardus) and European anchovy (Engraulis encrasicolus), compared to conventional extraction with oil-derived solvents such as n-hexane and with petroleum ether, show that the process has general applicability. Meeting the principles of green extraction and those of the marine biorefinery requiring high process efficiency, the process establishes an “innovation through integration” circular economy production route enabling the marine bioeconomy.
