A few bioeconomy companies have lately started production of valued bioproducts from fisheries by-products, especially of fish oil and fish proteins for the petfood industry. The shift from fish and krill to fish processing waste is particularly urgent in the case of fish oil production. Rich in omega-3 polyunsaturated fatty acids, indeed, the extraction of fish oil for the production of omega-3 food supplements contributes to overfishing across the world. Amid the new, low energy circular economy processes to recover valued bioproducts, the extraction of a whole fish oil named "AnchoisOil" (AnO) from Mediterranean anchovy (Engraulis encrasicolus) fillet leftovers using the biobased solvent d-limonene was first reported in 2019. Limonene indeed is an excellent solvent for lipids, but contrary to many oil-derived solvents it provides several health benefits being edible and widely used in the nutraceutical industry. The process is entirely circular and waste-free because after the extraction of the oil, the biobased solvent derived from orange and lemon peels prior to fruit squeeze and juice production is nearly entirely recovered, whereas the anchovy residue (AnR) is an exceptional organic fertilizer dubbed "AnchoisFert" (AnF). Named "LimoFish" (LiF), and conducted under ultramild conditions (ambient temperature and pressure), the new extraction process has significant practical relevance because it closes the fishing material cycle for the world's most fished species (anchovy) using a solvent that prevents microbial spoilage due to its powerful antimicrobial activity. The process cuts the cost of the conventional energyintensive fish oil extraction and refinement multi-step processes shifting the production of fish oil rich in omega-3 lipids from blue fish to blue fish waste. The capital investment is low and the operational costs limited to labor and electricity to separate the oil from the agro-solvent. Similarly, contrary to fish hydrolysate, fish emulsion, or fish silage, production of AnchoisFert does not require expensive chemical, enzymatic or thermal processing of fish biowaste. In this study, we apply the Life Cycle Assessment (LCA) methodology to evaluate the potential environmental burdens associated to the AnchoisFert and AnchoisOil production via the aforementioned LiF process. LCA was first applied to laboratory data. Then a scale-up of the novel process is proposed (according to well-known methods) and the LCA environmental assessment approach for modelling the production of chemicals, 15 is applied for an overall evaluation of the process at an industrial level.
