This study seeks to produced and analysed potash from banana peel and palm bunch in order to compare their proximate and elemental composition. The results of the analysis revealed that<strong> i</strong>norganic (ash) contents were 12.78, 21.40 and 18.60 mg/l for potash produced from banana peel, palm bunch and limestone. Corresponding values for fibre (3.65, 2.41, 18.60 mg/l), lipid (17.87, 16.50 and 13.56 mg/l), carbohydrate (5.23, 6.03 and 6.00 mg/l) and energy value (423.73, 387.26 and 342.28 J) were also estimated. The samples showed high concentration of calcium and potassium (which are essential elements), relatively low concentrations of iron and manganese (which are trace elements) and low concentrations of lead and cadmium, which are toxic metals. Although potash from banana peel and palm bunch waste displayed comparative nutrient and elemental functions, their usefulness maybe limited by the presence of heavy metals if not properly processed or checked.</p> Imeh J.
