“…[37] Algae and marine biorefineries are receiving increased attention in the scientific literature because of their untapped potential up to date, and could provide a new source of monomers and polymers in the future. [38,39] Another relevant fraction of biomass is lignin, which is the biggest source of biogenic aromatics available on Earth. The lignin biopolymer consists of a propylphenolic backbone based on three main building blocks-p-coumaryl, coniferyl and Biomass and other natural resources from which macromolecules can be extracted.…”

The establishment of novel biomass processing schemes is key for achieving the much-needed carbon neutrality and counteract global warming. Biomass provides a range of monomers and macromolecules with great potential to replace petro-based materials in a wide range of applications. While important developments are ongoing in the biorefinery space, cross-sectoral, multidisciplinary partnerships are paramount to speed up and de-risk the industrialization of such technologies, and an integrated view is necessary to achieve process feasibility. This perspective explores both bottom-up and top-down approaches for biomass valorization based on the main natural polymers and monomers that can be extracted or isolated from biomass. A special emphasis is put on scalability, economic feasibility, and resource availability while the biggest challenges in the path toward the development of biorefineries are also discussed.

“…The development and implementation of a successful marine bio-refinery can meet the goals of a “greener” socioeconomic development, also termed “blue economy”; a term is used as a synonym for “sustainable ocean-based economy” ( 111 ). The development and implementation of a marine biorefinery can be fundamental to consolidate a “greener” socioeconomic oceanic development ( 112 ).…”

“…Veríssimo et al ( 112 ) observed that biorefineries are sophisticated multi-step systems, requiring expertise in all stages of manufacturing, in addition to a clear vision of all raw materials, residues, and products. The attributes of a marine biorefinery are low cost of raw material, comparatively simple processes, lower energy consumption, and high productivity ( 131 ).…”

Scarcity of nutritive protein is a major global problem, the severity of which is bound to increase with the rising population. The situation demands finding additional sources of proteins that can be both safe as well as acceptable to the consumer. Food waste, particularly from seafood is a plausible feedstock of proteins in this respect. Fishing operations result in appreciable amounts of bycatch having poor food value. In addition, commercial processing results in 50 to 60% of seafood as discards, which consist of shell, head, fileting frames, bones, viscera, fin, skin, roe, and others. Furthermore, voluminous amounts of protein-rich effluents are released during commercial seafood processing. While meat from the bycatch can be raw material for proteinous edible products, proteins from the process discards and effluents can be recovered through biorefining employing upcoming, environmental-friendly, low-cost green processes. Microbial or enzyme treatments release proteins bound to the seafood matrices. Physico-chemical processes such as ultrasound, pulse electric field, high hydrostatic pressure, green solvent extractions and others are available to recover proteins from the by-products. Cultivation of photosynthetic microalgae in nutrient media consisting of seafood side streams generates algal cell mass, a rich source of functional proteins. A zero-waste marine bio-refinery approach can help almost total recovery of proteins and other ingredients from the seafood side streams. The recovered proteins can have high nutritive value and valuable applications as nutraceuticals and food additives.

“…Even though it is true that the waste biorefineries have been steadily increasing over the past years (mostly due to the adoption of the 2030 Agenda for Sustainable Development that obliges individual countries to take actions aimed at achieving the 17 goals of sustainable development) the same trend is not observed yet for the specific case of marine waste biorefineries [59].…”
