The global emphasis on food security and sustainability has generated great excitement in using food and agricultural waste for functional food invention, mostly because these byproducts are abundant sources of important nutrients, including dietary fibres, vitamins, minerals, and a varied range of phytochemicals renowned for their antioxidant, anti-inflammatory, antimicrobial, and prebiotic qualities. The main purpose of this study is to investigate current developments in bioprocessing techniques—including enzymatic hydrolysis, microbial fermentation, and green solvent extraction—which improve bioavailability, stability, and extraction of these compounds. Gathering data from current research, the review shows how these inventions aid in the transformation of waste into nutraceuticals and health-promoting functional substances. Unlike other reviews that concentrate just on waste management or functional food design, this study offers an integrative viewpoint connecting biochemical potential, technical inventions, health consequences, and environmental effects. It also covers socio-economic elements like consumer acceptance and policy integration, both of which are crucial for widespread adoption. According to this analysis, agri-food waste valorization is a crucial tactic in the circular bioeconomy, supporting zero-waste objectives, lowering greenhouse gas emissions, and assisting in sustainable food systems. In essence, it presents a plan for turning garbage into wellbeing, with both nutritional advantages and environmental awareness in quest of worldwide sustainability goals.
