Rice straw and rice husk fibers (RS/RH) reinforced polymer-based composites have theability to conserve wood and petroleum resources. As natural filler, rice straw and rice husk offer asustainable material for the production of polymer-based composites. The application ofbiocomposite limits the burning of straw at the root and may further enhance the socioeconomicstatus of farmers and rural populations. This review mainly focuses on five different weightpercentage of reinforced RS and RH fiber content (5%, 10%, 15%, 20% and 25%) in polymercomposites. Nowadays, Epoxy, polyurethane, polyester, PVA, PLA and polyethylene are beingused as matrix material in polymer composites. This paper holds good with understanding themechanical properties, pretreatment methods and offer important insight into potential uses ofpolymer composites with biodegradable reinforce fiber.

“…According to A. Ganesh Babu et al [34], bio-films were produced utilising the solution casting process employing liquid polyvinyl alcohol (PVA) and variable amounts (5-25wt percent) of rice husk flour as reinforcing filler. FTIR, XRD, TGA, DSC, Tensile test, Surface morphology investigations, WVP, and Antibacterial tests were used to examine the impact of RHP on the PVA matrix.…”

Due to the development of nanotechnology and changing customer demands for food safety and hygiene, the food packaging industry is growing significantly. In today's worldwide market, active packaging offers a number of advantages over traditional wrapping because of its capacity to absorb or release substances to improve the shelf life of food. Traditional food packaging materials are difficult to recycle and are made from nonrenewable fossil fuels. Development of Biodegradable films using Nano cellulose can be a good replacement for synthetic plastic packaging materials and can be a good solution for this problem. Other than that it has multiple advantages regarding tensile and physical properties, also in reducing health hazards. Tensile and physical characteristics are improved and water vapor permeability is decreased with the addition of cellulose nanoparticles to the biodegradable films/biodegradable composite films. The production of biodegradable materials employing Nano cellulose has been covered in this review study in four different ways, including extracts from agricultural waste, rice husk, various plant extracts, and biopolymer composite material in food packaging. The reason for using Nano cellulose based Biodegradable films in food packaging are also reviewed in this article. The key points for the future research in overcoming the problems related to Nano cellulose, biodegradable films are also predicted in the paper

Earth produces 2.12 billion tons of total wastes annually and nearly 2 million tons of petroleum-based synthetic polymers each day. The majority of synthetic polymers were obtained by packaging applications. Biodegradable films(biofilms) can be a good alternative for pollution-creating synthetic polymers.Rice hull powder (RHP) as reinforcing fillers, polyvinyl alcohol (PVA) as matrix along with silver nanoparticles (AgNPs) were used to prepare the biofilms. By using the solution casting method, five samples of PVA/RHP (1-5 mM) AgNPs biofilms were fabricated and characterized using Fourier transform infrared (FT-IR), X-Ray Diffraction Analysis (XRD), field emission scanning electron microscope (FESEM), Thermogravimetric Analysis (TGA) and differential scanning calorimetry beyond testing for their mechanical and antibacterial activities. The small spherical shape elements in the FESEM images clarify the presence of AgNPs. The intensities of observed peaks in the FT-IR spectrum keep decreasing with the inclusion of AgNPs. The X-ray diffractogram confirms the strong peaks at 2θ = 38.2 , 49.1 , 60.8 , & 78.3 due to the presence of the AgNPs. The tensile strength and tensile modulus reached a maximum value of 35.5 and 871 MPa respectively. The presence of heat-stable metallic silver made the biofilms thermally stable up to 371 C and also improved the antibacterial activity exhibited by a better inhibition zone. The improved results clarified that biofilms can be suggested for packaging applications.
