The cost to dispose of sludge is very high, and Malaysia usually treats it by composting.However, composting is not a feasible method because it is time consuming. The applicationof sewage sludge on cropland is economical method because it provides the plantnutrients. However, it has a serious impact on the plants, animal and environment due tohigh concentration of heavy metals. Therefore, phytoremediation is a green technologyto remove pollutants especially heavy metals from contaminated soil. This study wasconducted to determine the potential of Ricinus communis to remove heavy metal in soil.The seedlings were planted on six different planting media T0 (100% soil-Control), T2 (80%soil + 20% sewage sludge), T3 (60% soil +40 % sewage sludge), T4 (40% soil + 60%sewage sludge), T5 (20% soil + 80% sewagesludge) and T6 (100% sewage sludge). Thehighest accumulation of Mn was observedin leaves. Ricinus communis were foundto be suitable as phytoremediators to cleanheavy metals especially Mn as its TF valuewas higher than BCF.
