Development of biodegradable bioplastic films from Taro starch reinforced with bentonite

Single-use plastics are of great concern as they cannot be efficiently recycled and are non-biodegradable, causing pollution by accumulating in landfills and affecting marine organisms. Bioplastics can be used to replace such single-use plastics as they are biodegradable and renewable. This study us...
