Post Harvest Processing Of Rice Straw for Production Of Value Added Products

Abstract

As an output of agricultural practices large volumes of agro waste is generated, whose newlinemanagement and disposal is a global challenge. Rice straw is one such waste which is produced newlinein huge volumes. In the present study rice straw was utilized as study material for its postharvest newlineprocessing to produce value added products. Rice straw was processed to extract silica, newlineoil, cellulose and synthesis of Bio-MCM-41. Extracted silica exhibited bioremediation newlinepotential which was depicted by its potential to degrade methylene blue, indicating that rice newlinestraw extracted silica can be effectively applied for degradation of environmental pollutant with newlinespecific reference to dyes. Also, the degradation of methylene blue is reported to be newlinephotocatalytic degradation as no significant dye degradation was observed under darkness. The newlinecellulose extracted was utilized for preparation of biodegradable plastic film with utilization of newlinePVA as plasticiser. The bioplastic film synthesized exhibited durable properties in terms of tear newlinestrength. Bio-MCM-41 synthesized from rice straw acted as catalyst in pyrolysis of rice straw newlineresulting in enhanced oil production when pyrolysis was conducted in presence of catalyst newline(Bio-MCM-41) compared to non-catalytic pyrolysis. Residue obtained post Bio-MCM 41 newlinesynthesis was reutilized for synthesizing the catalyst. The process is a zero residue in terms of newlinecomplete utilization of rice straw in eco-friendly manner. The present study reports an effective newlineapproach to utilize rice straw for production of various products with distinguish applications newline
