In this paper we explored the Low Cost Agro-waste Adsorbents (Banana, Kenaf and Sugarcane Stems) used to Remove Toxic Dyes. As low-cost adsorbent, natural materials have promise as they are usable in vast amounts and environmentally safe. “In this analysis, kenaf, sugarcane bagasse and banana stem were selected for the purpose of evaluating their adsorption potential in textile waste water. Textile waste water for excess methylene blue dye on cloth was obtained during the washing out process. Wastewater has been analyzed according to the standard Process. Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Total Dissolved Solids (TDS), Total Suspended Solids (TSS), pH, total solids and turbidity are included in the study carried out. With this report, the emission level of waste water from the textile sector will be minimized and the 'reuse' policy for farm waste that will be sent to landfill for disposal if not used will also be established. The findings from this study indicate that at a concentration of 70 mg/L methylene blue dye, banana, kenaf stem and sugarcane bagasse exhibit more than 95 percent adsorption ability. Banana stem is the strongest of all adsorbents to extract methylene blue dye since it can reach the highest percentage (97.8%) of elimination with an adsorption capacity of 68.48 mg/L. Based on the rough capital cost evaluation for the development of agro-wastes, the cost involved varied from RM 1.20 to RM 2.90. Agro-wastes are more economical as adsorbents similar to activated charcoal. The use of agro-wastes (kenaf, banana stem and sugarcane bagasse) as adsorbents has been clearly demonstrated to be inexpensive, efficient and more viable. It can be used to strip methylene blue dye effectively.
