Biodegradables are materials that can be degraded by the enzymatic action of bacteria, yeast, and/or fungi; and they are also compostable when they act as fertilizers and
soil conditioners. Several commercially available synthetic polymers are biodegradable and compostable, including starch, cellu-lose, and lignin. Moreover, many bioplastics are a mix of synthetic components and are currently used in some packaging applica-tions such as trash bags, loose-fill packing foam, wrappings, and laminated papers, but also diaper back sheets, cotton swabs, toys,
