Biodegradable food packaging using agricultural wastes (Banana Pseudostem)
… from banana pseudostem as the main polymer for bioplastic formation. Alkaline treatment, bleaching, and TEMPO-mediated oxidation coupled with mild mechanical disintegration successfully removed non-cellulosic polysaccharides and isolated nano-sized fibre from banana pseudostem. The nanocellulose …
