Farm products offer a wide range of commodities such as cellulose, starch, rubber, and other materials that are environmentally friendly. Starch, one of the promising natural materials, most abundantly available after cellulose, has been considered a good candidate in thermoplastic technology. The low price and the availability of starch in addition to its very favourable environmental profile, have, in the past 15 years, aroused a renewed interest in starch-based polymers as an attractive alternative to polymers based on petrochemicals.
