Comparative analysis is a method of comparing and contrasting two or more subjects in order to evaluate their similarities and differences. This type of analysis can be applied to various fields, including business, economics, politics, literature, and science. Water Hyacinth products are affordable but labour-intensive, while bamboo products are more expensive but highly durable. Stubble-based products have limited consumer applications but can generate income through industrial sales. Overall, the economic potential of these products lies in their widespread adoption and innovation in their production methods. The greatest ash concentration (carbonate, Ca, K, etc.) was found in water hyacinth. The two raw materials (i.e. water hyacinth and bamboo) had lower ash contents than stubble, which had an ash concentration of above 15%. Because it decreased the mechanical strength qualities of the pulp, the high ash concentration was unexpected. All of the materials had a lignin level that was rather high, with bamboo having the most. This indicates that additional chemical ingredients and a longer heating time are needed to prepare bamboo pulp. The highest holocellulose content was found in bamboo, which produced pulp with the best quality due to its strong fibres, high water absorption, insolubility in water and organic solvent. Hemicellulose expanded in water, speeding the fibrillation and affecting water absorption at the time of cooking.
