Conversion of fish processing waste to value-added commodities: a waste to wealth strategies for greening of the environment

By 2030, there should be 8.6 billion people on the planet, and there will be a 62.5% increase in fish consumption. As natural resources and stocks diminish, it will become more challenging to feed the population. The trash produced by the processing sector was formerly thought to be worthless. When fish is processed, roughly 50%–60% of its original weight is discarded in landfills because fish and shellfish are thought to be perishable and readily spoilable. This results in environmental pollution. Every product that is made produces garbage; however, several studies have shown that this waste also includes nutrients that may be exploited as a resource to create by-products. The industrial manufacture of value-added fishing products results in significant quantities of nutrient-rich discards and process effluent. These bycatch, discards, and effluents include a lot of nutrients, important industrial components, and bioenergy. Innovative eco-friendly green methods for biorefining discarded seafood are now possible because of advances in marine biotechnology. The importance of nutrient-rich seafood waste and its applications in numerous fields are explored in this article.
