Almost 2 % of the entire plastic eventually get to the surronding, leading to sensitive polution harms. In addition polyethylene is petroleum based which is depleting with time. In this circumstance biobased plastic have gaind extensive significance as a possible alternative. Various bio degradable polymer have been developed. However, they have high cost and lower mechanical properties.To address this issue, different attemts are carried out such as blending of bio-polymeric renewable resourcess with polyolefins. Starch, chitin, chiyosan and cellulose are widely used as biodegradable additive.In the present work bio degradable composites were synthesized from polyethylene and biobased additive such as starch. The compatibility of the polymer matrix and additive was enhenced with maleic anhydride grafted polyethylene and vinyltrietthoxy silane. The book deals with a comprehansive introduction to type of composites, matrix, polyethylene and polysaccharides. A brief discusion of previous literature is also incorporated.
