Development and analysis of rice hull powder polyvinyl alcohol biodegradable composite films

Abstract

Nowadays, modern science and technology consider synthetic newlinepolymers as a supreme gift to mankind. Based on its importance in multifarious newlineapplications such as packaging, transportation, consumer products, industrial newlinesectors, medical appliances, and food materials, it has become as irreplaceable newlinefor modern society. The features like low cost, easy method of fabrication, and newlineconvenience for usage have made human life without synthetic polymer to be newlineunimaginable. The world produces over 250 million tons of synthetic polymer newlineproduces in recent years. More than 80 percent of the synthetic polymers used newlinefor short-term usage (single-use purposes) can be long-lasting and have high newlinepersistence in the environment. The problems like difficulties in waste disposal newlineand global warming have raised huge concerns among researchers. newlineTo overcome the white pollution created by synthetic polymers, a newlinenovel biodegradable polymer is essential for this twenty-first century. So bio newlinebiodegradable polymers like PPC, PLA, and PHA are used to fabricate newlinebiocomposite films along with natural fillers to improve their application in newlinevarious fields. But the problem is that biodegradable polymers have certain newlinelimitations in physical properties like strength durability and dimensional newlinestability and the polymers were difficult to process. newlineAgricultural wastes aka agro waste which consists of crop waste, newlineresidues of plants, animal waste, food processing waste, etc., are available in newlinelarge quantities. Unused agro waste may cause problems to the environment like newlinelandfilling and emission of toxic gas etc., some of the recent work suggests that newlinenaturally obtained waste materials like orange peel, groundnut shell, and banana newlinepeel were powdered and used as a filler material to mix with biodegradable newlinepolymer matrix. newline
