Microwave Assisted Extraction of Raw Alginate as a Sustainable and Cost-Effective Method to Treat Beach-Accumulated Sargassum Algae

This paper highlights the potential of Sargassum algae, recovered from raw beach seaweed wastes, as a valid source valuable sodium alginate. Alginate is biodegradable, highly attractive polysaccharide widely used in food, pharmaceuticals, and biomedicine applications. The aim this work to employ new eco-sustainable cost-effective extractive method obtain alginate material pollutant organic seaweeds. Algae were exposed microwave pre-treatment under static dynamic conditions, three different protocols followed: (a) conventional, (b) hot water (c) alkaline method. All samples characterized by GPC, SEM, FTIR/ATR TGA. It was found that alginate’s best performances obtained followed protocol. Nevertheless, algae allowed easiest breaking their cell walls following fast releasing authors demonstrated microwave-enhanced extraction an effective way Sargassum-stranded waste materials approach. They also assessed applications mulching films for agricultural
