Abstract
Agroindustry biomass are unlimited source for lignocellulosic ecofriendly nanocellulose fibres, with potentials as hydrophobic structural enhancers in biopolymer applications. Two major concerns in producing cellulose nano crystal (CNC); are obtaining a source not competing with food and a low-cost effective method to produce CNC. Alkali pre-treatment combined with a mechanical treatment was performed on Giant Swamp Taro (GST) starch processing waste. The alkali pre-treatment was useful in eliminating hemicellulose. The following disintegration process (ultrafine grinding) resulted GST CNC at the sizes of 449.6 nm to 78.26 nm. CNC results were thin flakes with fibrous network which appeared like nanowhiskers. Traces of coastal ecosystem mineral and rare elements are found in GST CNC as indicated in EDS, after all GST is a coastal plant. Meanwhile towards heat treatments, the GST CNC was relatively stable and was observed to also have a 2-step decomposition at 110°C and 359.87°C.
