FABRICATION OF BIODEGRADABLE AND ECO-FRIENDLY ALGINATE-BASED PLASTIC FROM JOLYNA LAMINARIOIDES WITH PHYSIO-CHEMICAL CHARACTERIZATION

Abstract
Sodium alginate was extracted from brown seaweed Jolyna laminarioides collected during low tide from coastal area of Karachi. Alginate was used as renewable source for production of eco-friendly bioplastic by casting technique. Starch was mixed with alginate as secondary polymer along with high (30%) and low (15%) concentration of bio-plasticizer (sorbitol and glycerol). Thickness, moisture content, solubility, soil burial test, density, scanning electron microscopy (SEM) and fourier transform infra-red spectroscopy (FTIR) was performed for each blend of bioplastic. The obtained results showed the affinity of sorbitol and glycerol with alginate-starch matrix with significant moisture content, thickness, and biodegradation properties. It was also observed that increasing the concentration of plasticizer affected physical and chemical features of bioplastic films.
