Description
Summary:Pressmud are one of the major wastes are producing abundantly in sugar industries every year in Penang, Malaysia. Pressmud which is also known as mud cake, is a residual output after the filtration of the juice. Besides that, the major biomass byproduct from the palm oil industry is empty fruit bunch (EFB). EFB have a great potency as basic raw materials used for the fermentative production because they contain 37.3–46.5 %cellulose, 25.3–33.8% hemicelluloses. This study was carried out to determine the potentiality of these wastes by amending with the local soil in landfill in order to improve the properties of the landfill daily cover and to evaluate the effect of combining pressmud and EFB in the local soil. The adsorption isotherm curves of heavy metals were observed in order to determine the best mixture performance. The local soil was mixed with pressmud and EFB at different percentages of weight ratio namely 50S:40P:10E, 50S:30P:20E, 50S:25P:25E, 50S:10P:40E and 50S:20P:30E respectively. The local soil-pressmud-EFB mixtures of seem to be more effective to remove most of the heavy metals from the solution as compared to soil alone as the heavy metals adsorbed, q (mg/kg) increased with the increasing of equilibrium concentration, Ceq (mg/L). From the results, the highest amount of a contaminant adsorbed from the heavy metals solution was 50S:40P:10E followed by 50S:30P:20E. This indicated that the highest percentage amount of pressmud in the mixtures increases the amount of q value adsorbed. Therefore, this proposed soil-pressmud-EFB mixtures has a potentiality to be used as a daily soil cover in landfill instead of using local soil alone.
