Abstract

This research focuses on the fibrillation and characterization of nanocellulose fibers derived from spent tea leaves. Spent tea leaves (STL) are known as one of the renewable lignocellulosic wastes that are biodegradable and no negative impact to the environment. The objectives of this research are to determine the viability of extracting nanocellulose fiber from STL and to characterize the extracted nanocellulose STL fibers by Optical Microscopy, Scanning Electron Microscopy, Field Emission Scanning Electron Microscopy, X-ray Diffraction, Fourier Transform Infrared Spectroscopy and centrifugation method. This research deduces the production and characterization of nanocellulose fiber derived from STL. Two grades of STL are used in this research, which are BHE-BM and BHE-SW from the stalk of the tea plant. The extracted nanocellulose samples are subjected to microscopic observations, physical and chemical characterization, and fibrillation yield determination. From this research, the characterization and analysis results have shown that the STL of finer grade BHE-SW provides better fibrillation yield of 15.22% than the coarser grade BHE-BM with fibrillation yield of 14.68%. Furthermore, the effect of fibrillation parameters such as blending speed and blending time are compared within both grades of STL in this research.
