“…18 On the other hand, SU model has been elaborated referring to the methodologies described by Maranghi and co-workers 15 and Piccinno. 19 In both cases, the partial lack of useful data has been offset by the elaboration of assumptions, validated and justified by considerations based on previous studies found on the literature or relying on the Ecoinvent database. 18 The unitary processes are listed in ESI (Table S1).…”

“…The electricity input to allow a proper mixing of 1 kg of AnR is 6.2 Je/FU in the lab scale (LS) and 28.8 Je/FU in the scale up (SU). The virgin (68.8 g/FU on laboratory scale and 45 g/FU on industrial scale) 19,25 and recycled limonene (1.86 kg/FU on laboratory scale and 1.21 kg/FU on industrial scale) were entered at 50% rate in the blending step and at 50% rate in the extraction step. For both the LS and SU the output of the blending process was 2 kg/FU of leftovers puree at low grade.…”

AnchoisFert and AnchoiOil are a new organic fertilizer and a new whole fish oil obtained via the circular economy “LimoFish” process based on extraction of the oil from anchovy fillet leftovers with agro-solvent limonene followed by mild drying of the solid residue. We apply the Life Cycle Assessment methodology to evaluate the environmental burdens associated to production of AnchoisFert and AnchoisOil via the aforementioned process at laboratory and industrial scale. Furthermore, we compare the environmental sustainability of AnchoiFert production with conversion of the solid residue into biomethane to produce electricity. The study fills a gap in the literature concerning the environmental soundness of this new circular economy process. Its outcomes will be instrumental to inform its broad evaluation en route to scale-up and industrialization.

“…For example, it was recently proven to have a unique ability to recover marine oils rich in omega-3 lipids, vitamin D and carotenoids from shrimp and anchovy leftovers [20][21][22]. These uses are particularly important in light of its anticancer, anti-tumoral and anti-diabetic properties [23,24]. The industrial demand of limonene largely exceeds its supply, limited by the yearly global production of orange crops.…”

The Limonene Biorefinery: From Extractive Technologies to Its Catalytic Upgrading into p-Cymene

Limonene is a renewable cyclic monoterpene that is easily obtainable from citrus peel and it is commonly used as a nutraceutical ingredient, antibacterial, biopesticide and green extraction solvent as well as additive in healthcare, fragrance and food and beverage industries for its characteristic lemon-like smell. Indeed, the lack of toxicity makes limonene a promising bio-alternative for the development of a wide range of effective products in modern biorefineries. As a consequence, industrial demand largely exceeds supply by now. Limonene can be also used as starting substrate for the preparation of building block chemicals, including p-cymene that is an important intermediate in several industrial catalytic processes. In this contribution, after reviewing recent advances in the recovery of limonene from citrus peel and residues with particular attention to benign-by-design extractive processes, we focus on the latest results in its dehydrogenation to p-cymene via heterogeneous catalysis. Indeed, the latest reports evidence that the selective production of p-cymene still remains a scientific and technological challenge since, in order to drive the isomerization and dehydrogenation of limonene, an optimal balance between the catalyst nature/content and the reaction conditions is needed.
