During the last two decades, a considerable amount of research has been focused on the development of eco-friendly ''green'' biodegradable composites that can replace the artificially-synthesized petroleum-based composites [1]. Such efforts are attempting to satisfy the increased demand of creating a resource-circulating society, which poses no resource-shortage-related problems [2].
