This book presents the latest developments in the field of vegetable oil -based composites. It focuses on different vegetable oils such as castor, linseed, corn, soybean, olive, palm, and canola oils;, and fillers from inorganic materials and agricultural residues used in the preparation of vegetable oil -based composites. There are several advantages to vegetable oil-based polymer composites, due to their universal availability, inherent biodegradability, low price, and superb environmental credentials (i.e., low eco-toxicity and low toxicity towards humans). This book will be of is of interest to researchers working in the field of bio-based composite materials for the development of green and sustainable materials.
