The global demand for potassium-based fertilizers, such as potash, has surged due to its essential role in agriculture. This study explores the potential of agricultural waste, specifically sesame seed waste and rice husks, as sustainable sources for potash production. The aim of the research was to determine the percentage composition of compounds and elemental concentrations in both materials, using X-ray diffraction (XRD) and Atomic Absorption Spectroscopy (AAS) techniques. Results revealed that rice husks contained 38.33% potassium oxide (K2O), 17.26% calcium oxide (CaO), and 6.25% sulfur trioxide (SO3), while sesame seed waste exhibited a higher potassium concentration of 58.04% K2O. Elemental concentration analysis showed rice husks to contain 35.49 mg/kg potassium, and sesame seed waste had a notably higher concentration of 55.91 mg/kg potassium. Both materials demonstrated promising potassium content, positioning them as viable alternatives for potash production. The use of agricultural waste for potash extraction not only offers a sustainable solution for waste management but also provides an eco-friendly, cost-effective source for fertilizer production. These findings suggest that further developments in potash extraction techniques from these materials could significantly contribute to global agricultural and industrial needs.
