Abstract: The present processes are used to convert green algae into a moldable bioplastic. Specifically, the present processes use a green alga such as Cladophora sp. Combined with myrrh to obtain the moldable bioplastic. Once obtained, the moldable bioplastic can form a composite, optionally with other environmentally friendly materials, to obtain eco-friendly products, such as a biodegradable and sustainable container such as a bag.

Abstract: A plastic pro-biodegradation additive includes a carrier polymer and a nanostarch compound. The nanostarch compound can include nanostarch with a particle size in a range of about 40 to about 500 nm. The nanostarch compound can include small-size and/or large-size regular starch. The carrier polymer can be a biodegradable polymer. The additive can include: a polysaccharide; an organic filler; one or more of a monosaccharide, a disaccharide and an oligosaccharide; a surfactant; and/or an inorganic filler. The carrier polymer can include a non-biodegradable polymer. Biodegradable plastic compositions and methods of preparing a biodegradable plastic material are also disclosed.
