EFFECT OF ALKALINE TREATMENT ON MORPHOLOGY AND BIODEGRADATION OF BAGASSE AND MAIZE CELLULOSE

This study investigates the biodegradation behaviour of cellulose extracted from sugarcane bagasse (SCB) and maize using chemical treatments involving sodium hydroxide (NaOH), sodium chlorite, and buffer solutions (NaOH and glacial acetic acid). The extraction process yielded cellulose at 38.00% from SCB and 45.14% from maize, based on the weight of the raw material. The resulting celluloses were characterized using Fourier transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD), confirming their structural and chemical integrity. Biodegradability was evaluated through composting tests, revealing weight losses of 9.08% for SCB cellulose and 29.47% for maize cellulose. The higher degradation rate of maize-derived cellulose suggests enhanced biodegradability

Comparison of fibre from maize stalk domains and sugar cane bagasse

The aim of this study is to investigate properties of pulverised cellulosic material from parts of maize stalks and sugar cane bagasse (SCB). Both materials were foremost subjected to a cutting mill before boiling with water. The chemical compositions and mechanical properties of the maize stalk residues and sugar cane bagasse were performed using a TAPPI standard. Optical microscope, Fourier-transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), thermogravimetric analysis (TGA) and Ultraviolet-visible spectroscopy (UV-Vis) were used to characterise the materials. Rind displays thinner and longer fibres, which are less unequal and almost quadrangular. In fact, it has a highest crystallinity trailed by nodes and sugar cane bagasse in sequence. Interestingly, thermal stability of SCB is dominating followed by rind and nodes.
