“…Valorization of the feedstock is based on the “3R” strategy, namely, “reduce” the waste as much as possible, “reuse”, and after “recycle”. An ecologically conscious valorization approach based on the above strategy minimizes the biowaste, develops valuable products, improves food security and nutrition, and provides economic profit and social benefits, within the concept of a circular economy. , Because of the regenerative nature of seafood biomass, its utilization is highly significant. An ecologically conscious valorization of the biomass using green chemistry based technologies can reduce the seafood side streams, environmental pollution, improve sustainability, and encourage blue economy.…”

A major challenge facing sustainable seafood production is the voluminous amounts of nutrient-rich seafood side streams consisting of by-catch, processing discards, and process effluents. There is a lack of a comprehensive model for optimal valorization of the side streams. Upcoming green chemistry-based processing has the potential to recover diverse valuable compounds from seafood side streams in an ecofriendly manner. Microbial and enzymatic bioconversions form major green processes capable of releasing biomolecules from seafood matrices under mild conditions. Novel green solvents, because of their low toxicity and recyclable nature, can extract bioactive compounds. Nonthermal technologies such as ultrasound, supercritical fluid, and membrane filtration can complement green extractions. The extracted proteins, peptides, polyunsaturated fatty acids, chitin, chitosan, and others function as nutraceuticals, food supplements, additives, etc. Green processing can address environmental, economic, and technological challenges of valorization of seafood side streams, thereby supporting sustainable seafood production. Green processing can also encourage bioenergy production. Multiple green processes, integrated in a marine biorefinery, can optimize valorization on a zero-waste trade-off, for a circular blue economy. A green chemistry-based valorization framework has the potential to meet the Sustainable Development Goals (SDGs) of the United Nations.

“…It has been estimated that approximately 36% of seafood can be wasted. The quantities, quality, and value of these SFBP can vary from species to species, between regions, and at different stages of the production process (Cooney et al., 2023). The major SFBP typically consists of biomass produced during the preparation or processing of raw material, which is further converted to seafood products for consumers (Ozogul et al., 2021).…”

Biopolymers derived from seafood processing byproducts are used to prepare active and biodegradable films as the packaging of food products. These films possess bioactivities to enhance the shelf life of packed foods by proactively releasing antimicrobial/antioxidative agents into the foods and providing sufficient barrier properties. Seafood processing byproducts are an eminent source of valuable compounds, including biopolymers and bioactive compounds. These biopolymers, including collagen, gelatin, chitosan, and muscle proteins, could be used to prepare robust and sustainable food packaging with some antimicrobial agents or antioxidants, for example, plant extracts rich in polyphenols or essential oils. These active packaging are not only biodegradable but also prevent the deterioration of packed foods caused by spoilage microorganisms as well as chemical deterioration. Seafood discards have a promising benefit for the development of environmentally friendly food packaging systems via the appropriate preparation methods or techniques. Therefore, the green packaging from seafood leftover can be better exploited and replace the synthetic counterpart.

“…This approach also promotes the valuation, reincorporation, and reuse of by-products, residue streams, and waste. 24,25 For the construction of circular economy models and indicators, it is pertinent to characterize the source, type of waste and/or by-product, generation rate and current disposal, as developed by authors in international research. 25 In order to apply the circular economy principle to FTS, it is necessary to look at the entire synthesis process as a whole and analyze all product phases including by-products.…”

The circular economy is considered a keystone of sustainable development, and its implementation requires analyzing both product and by‐products, as well as process waste. In this study Fischer‐Tropsch synthesis product selectivity over Fe/SiO2 catalyst was investigated in the reaction temperature range of 240 to 300°C. The composition of the gas, liquid hydrocarbon, and wax products is discussed alongside the aqueous phase, which is rarely addressed. It was found that 280°C is the optimal temperature for condensable hydrocarbon production over Fe/SiO2 catalyst. The increase in reaction temperature led to a decrease in the selectivity of 1‐olefins and alcohols in the liquid hydrocarbon phase and waxes, but at the same time contributed to an increase in the content of alcohols in the aqueous phase products.
