1 biodegradable green composites 1 sreerag gopi anitha pius and sabu thomas 11 introduction 2 12 biodegradable polymers 2 121 starch 2 122 cellulose 4 753 lignin reinforced biodegradable composites 187 754 lignin reinforced foam based composites 188. Topics include the elucidation of important aspects surrounding chemical and green approaches for the surface modification of natural fibers the use of recycled waste properties of biodegradable polyesters methods such as electrospinning and applications of hybrid composite materials. All composite materials showed a degree of biodegradation similar to the biodegradation rate of ddgs and cellulose this study showed that the incorporation of ddgs into a pbat matrix can produce green composites with enhanced biodegradability. Polylactic acid pla banana fiber green composite coupling agent introduction crude oil prices have soared in recent years doubling between 2003 usd 281 a barrel and 2006 usd 6124. In this study the fiber recycling from disposable chopsticks was chemically modified by coupling agents furthermore the modified fiber was added to the biodegradable polymer polylactic acid pla to form novel fiber reinforced green composites
