Non-wood materials which are cassava peels and cocoa pod husks are potential fibre sources of pulp and paper production. These materials were used as pulp for paper production industries to promote the concept “from waste to wealth” and “recyclable material to available product” for reducing the environmental issues. In order to maximize the utilization of non-wood fibres for pulp and paper production, a more complete understanding of its chemistry is required. In this context, the main objective of this work is to improve and investigate the chemical composition of different material fibers used for pulp and papermaking. All the determinations of chemical compositions were in accordance with relevant Technical Association of the Pulp and Paper Industry (TAPPI) Test Method, Kurscher-Hoffner approach and Chlorite method. The holocellulose, cellulose, hemicellulose, lignin, hot water and 1% NaOH solubility, ash and moisture content are parameters that involved in chemical characteristics determination. The scanning electron microscopy (SEM) was used to visualize the surface morphological of materials. In order to propose the suitability of the studied plant as alternative fibre resources in pulp and paper making, the obtained result is compared to other literatures especially wood sources. Results indicated the amount of holocellulose contents in cassava peel (66%) is lower than wood plants. But, cocoa pod husks (74%) are higher than that Pine pinaster (70%) in holocellulose content. Besides that, lignin content (7.5 – 14.7%) of alternative fibre is lower than those wood species (19.9-26.22%). From SEM images, cassava peels contained abundance fibre rather than cocoa pod husks. Cassava peels have impurities in white colour on surface fibre. Besides that, cocoa pod husks have a rough surface to protect their fibre. In conclusion, chemical properties and morphological characteristics of cassava peels and cocoa pod husks indicated that they a promising to be used as an alternative fibre sources for pulp and paper making.
