“…In addition to the share of world fish production utilized for direct human consumption, the use of byproducts is increasingly gaining attention, as they offer a significant and sustainable source of high-value bio-compounds, due to their high content of collagen, peptides, chitin, polyunsaturated fatty acids (PUFAs), enzymes, and minerals, suitable for biotechnological or pharmaceutical applications with high market value [ 10 , 11 , 14 , 38 , 39 , 40 , 41 , 42 , 43 , 44 ].…”

“…In 2016, the global production of fish oil from byproduct accounted for 26% of the total fish oil production [ 223 ]. In both the fishing and aquaculture industries, oil and fats represent a significant fraction of finfish processing waste and the amount of which depends upon the fat content of the specific fish species, the distribution of fat in fish parts, its age, sex, nutritional status, health, and time of year determine the amount of oil/fats [ 41 ]. For example, it is well noted that the visceral mass of fish discards has a significant amount of oil or fat apart from proteins [ 224 ].…”

“…Fish are not able to synthetize omega-3 but they need to obtain them from the external, through algae and microalgae or plankton in their diets. A wide range of techniques have been used to extract oil from whole fish or fish waste and reported in several reviews [ 41 , 228 , 230 ]. The selection of the most suitable method depends on different factors, especially by the nature of the waste and by the final application of the oil, whose biodiesel production and food supplements are the most common [ 46 , 231 ].…”

Following the growth of the global population and the subsequent rapid increase in urbanization and industrialization, the fisheries and aquaculture production has seen a massive increase driven mainly by the development of fishing technologies. Accordingly, a remarkable increase in the amount of fish waste has been produced around the world; it has been estimated that about two-thirds of the total amount of fish is discarded as waste, creating huge economic and environmental concerns. For this reason, the disposal and recycling of these wastes has become a key issue to be resolved. With the growing attention of the circular economy, the exploitation of underused or discarded marine material can represent a sustainable strategy for the realization of a circular bioeconomy, with the production of materials with high added value. In this study, we underline the enormous role that fish waste can have in the socio-economic sector. This review presents the different compounds with high commercial value obtained by fish byproducts, including collagen, enzymes, and bioactive peptides, and lists their possible applications in different fields.

Production of Jet Biofuels by Catalytic Hydroprocessing of Esters and Fatty Acids: A Review

et al. 2022

The transition from fossil to bio-based fuels is a requisite for reducing CO2 emissions in the aviation sector. Jet biofuels are alternative aviation fuels with similar chemical composition and performance of fossil jet fuels. In this context, the Hydroprocessing of Esters and Fatty Acids (HEFA) presents the most consolidated pathway for producing jet biofuels. The process for converting esters and/or fatty acids into hydrocarbons may involve hydrodeoxygenation, hydrocracking and hydroisomerization, depending on the chemical composition of the selected feedstock and the desired fuel properties. Furthermore, the HEFA process is usually performed under high H2 pressures and temperatures, with reactions mediated by a heterogeneous catalyst. In this framework, supported noble metals have been preferably employed in the HEFA process; however, some efforts were reported to utilize non-noble metals, achieving a similar performance of noble metals. Besides the metallic site, the acidic site of the catalyst is crucial for product selectivity. Bifunctional catalysts have been employed for the complete process of jet biofuel production with standardized properties, with a special remark for using zeolites as support. The proper design of heterogeneous catalysts may also reduce the consumption of hydrogen. Finally, the potential of enzymes as catalysts for intermediate products of the HEFA pathway is highlighted.

Engineering the wettability of functional materials holds significant interest, focusing on the need for superhydrophobic catalysts, crucial for their ability to prevent the poisoning of active sites by water, produced in situ or as a by‐product. Herein, for the first time, a superhydrophobic spherical activated carbon (SSAC@PhSO3H) is engineered as a catalyst via a novel synthetic approach and tailored in Jatropha curcas oil (JCO) biodiesel synthesis. With a large surface area (1461 m2 g−1), high acid density (6.26 mmol g−1), and water contact angle (163.4°), the catalyst demonstrates superior performance and remarkable water repellency, firmly establishing its superhydrophobic characteristics. Response Surface Methodology based on the Central Composite Design (RSM‐CCD) approach predicted a maximal biodiesel yield of 98.8% (80 °C, 5 wt%, 15:1 methanol to oil molar ratio (MOMR), and 40 min). Life cycle cost analysis (LCCA) estimates biodiesel production cost of 0.37 USD ($) per kg emphasizing high commercial viability. Compared with H2SO4‐sulfonated biochar, SSAC@PhSO3H retains its inherent activity (86.8 ± 0.4% yield in 10th run) and spherical morphology even after nine successive reaction cycles indicating high stability. Nevertheless, JCO biodiesel's fuel properties met European Norm, EN 14 212 and American Society for Testing and Materials, ASTM D6757 standards, highlighting its potential for industrial biodiesel production.
