In this work, we have adopted an environment-friendly method where carbon dot (CD) prepared from soy protein isolate is used to prepare AgNPs. AgNP (1% wt.) and different concentrations of chitin nanowhisker (CNW) (2- 10% wt.) were added to soy protein isolate to fabricate nanocomposite films. The prepared SPI based bionanocomposite films were characterized by FTIR, XRD and SEM. Commercial production of such SPI films would revolutionize the food packaging industry given its health benefits and cost effectiveness.

Accumulation of this biomass in large quantities every year results not only in the deterioration of the environment but also in the loss of potentially valuable material which can be processed to yield a number of value added products, such as food, fuel, feed and a variety of chemicals. The use of agricultural wastes as renewable resources of chemicals and fuels is of interest from both economic and environmental point of view. Lignocellulosic biomass encompass all agricultural wastes such as straw, stem, stalk leaves, husk, shell, peel, pulp, etc. Lignocellulosic biomass can act as a potential source for the production of chemicals such as ethanol, reducing sugars, furfural, etc. Furfural is a valuable by-product that is commercially produced by dilute acid hydrolysis from lignocellulosic wastes in an aqueous medium. Furfural is an important renewable platform chemical which can be converted to bio chemicals and biofuels. This project focuses mainly on the production of furfural from Kerala’s own indigenous crop waste i.e. rice husk and a local invasive floating plant commonly known as water hyacinth. The production of furfural from the above mentioned lignocellulosic biomass has been carried out via sulphuric acid catalysed hydrolysis in water solvent system. Comparison of the yield of furfural from rice husk and water hyacinth has also been investigated. The characterization of the product was carried out by FTIR, UV and 1H NMR spectroscopy.

In this work, carbon dots were synthesized from orange juice extract by a wet chemical method method. The optical and morphological properties of synthesized carbon dots were characterized by UV-visible spectroscopy, Photoluminescence spectroscopy,Dynamic Light Scattering and Transmission Electron Microscopy. Antimicrobial properties of carbon dots were studied by Diffusion Assay Method. The synthesised carbon dots was successfully conjugated with boric acid and was utilized for the detection of glucose. The luminescence intensity of carbon dots was found to be increasing upon glucose addition which was due to the formation of complex between the boric acid conjugated carbon dots and glucose. In the present work, photoluminescent, cost effective and biocompatible carbon dots were synthesised which are promising candidates for various optical and biological applications.

Biological processes generally are not capable to remove the pollutants present in the textile effluents. Advanced Oxidation Processes (AOPs) can produce a total mineralization, transforming recalcitrant compounds into inorganic substances or partial mineralization, transforming them into more biodegradable substances. In this study, solid sludge, formed as a result of addition of herbal coagulant in the real time textile effluent, and the filtrate are treated with two major AOPs such as ultrasound cavitation and ozonation process for the decomposition of solid sludge as well as removal of COD from the filtrate obtained from effluent to less than 150mg L-1 .The US cavitation process and ozonation process is carried out at five different pH from 2-10. US power is varied in the range of 50-250 W and ozone flow rate varied in the range of 2-6 g h-1 .The sludge decomposition and COD removal at these conditions are studied in this investigation.
