Valorization of Marine Waste Towards the Production of High-Value-Added Products, Bioplastics, and Other Industrial Applications

The maritime environment is a largely unknown and underappreciated source of functional components that can be employed in a variety of applications such as food preparation, storage, and enrichment. Marine microorganisms could provide new bioactive compounds with potential human use. Marine biomass embodies a biotechnological resource characterized by a wide range of compositions and functional attributes stemming from diverse bioactive elements such as polyphenols, peptides, and polysaccharides. Covering over 70% of the Earth’s surface, oceans and seas are vital contributors to the global economy, serving as both critical zones for the fishing industry and essential logistical pathways for mineral extraction and fossil fuel utilization. These activities all result in waste. The creation of high-value-added products from these by-products has accelerated recently due to the discovery of a wide range of biopolymers, nutrients, and functional chemicals that may be used for human consumption or in the pharmaceutical, animal feed, and other sectors. The concept of valorization, a sustainable method of turning marine garbage into useful resources, is explored in this book chapter. Additionally, the book chapter adopts a thorough thematic approach to the valorization of marine trash, covering the main contributions made by marine biotechnology to the creation of a circular economy. These contributions range from energy and valorization for biomedical enrolments to bio remedial enrolments for pollution. The chapter goes on to discuss the manufacture of various value-added goods such as fish meal, biodegradable plastics, chitin and chitosan, biofuels, marine collagen, and so on. Besides the different industrial applications of marine waste to fabricate bioactive compounds, construction materials, pharmaceuticals, agricultural fertilizers, etc., are intensively elaborated. The recovery of marine waste represents a promising way to solve environmental problems and, at the same time, creates economic opportunities using innovative technologies and sustainable practices. This work highlights efficient and environmentally conscious use of marine resources, supporting the preservation of our oceans and the well-being of future generations.
