| Outline of Final Research Achievements |
The research project stated to achieve two main objective which are to obtain cellulose through green methods and production of packaging materials using cellulose obtained from rice husk.
In the first objective, cellulose was successfully obtained using combination of green methods of NaOH and weak acid pretreatment and compared with the commercial solvent used which is using chlorinated methods. The cellulose obtained using green methods was smaller particle in size as compared to chlorinated methods.
In second objective, cellulose was reinforced with starch in order to improve the strength and properties of starch film prior to packaging purposes. The reinforced cellulose-starch matrix increase the mechanical properties of starch with high crystallinity and thermal properties obtained.

| Academic Significance and Societal Importance of the Research Achievements |
Utilisation of untapped biomass resources by adopting green recovery method for cellulose extraction devoid the use of organic solvents, cheaper in cost and reduce amount of waste generated in the mill. Understanding and mechanisms of extraction process was documented for the scientific community.
