Abstract: The industrial use of plant matter for cellulose production shortens the scarce available flora that could be employed for other wants, hence, there is need for alternative source for producing cellulose to meet industrial demands. Cellulose was produced using a modified acid hydrolysis, alkali and bleaching treatments on dewaxed Caesalpina bonduc hard nutshells (CBHNS). The micro-morphology, chemical functional groups, crystallinity and thermal stability of the resulting cellulose were characterized using the SEM, FTIR spectroscopy, X-ray diffractometry and thermogravimetry. The applied treatment protocol on CBHNS resulted in a whitish rod-like micro crystalline cellulose devoid of hemicellulose and lignin, with a crystallinity index of 87.5% in a temperature range of 240 – 470 °C. These observations show that CBHNS could be repurposed for cellulose production.
