Opis:: The use of heavy metals in the manufacturing industry over the past few decades has eventually contributed to a rise in the flow of metallic compounds into wastewater and has raised significant ecological and health threats to living things. Adsorption is an excellent way to treat solid waste effluent, offering significant benefits such as affordability, profitability, ease of operation and efficiency. However, the price of commercial adsorbent namely activated carbon has soared due to its high demand. There is also a green improvement in this method by turning the commercial adsorbent into agricultural waste. In Malaysia, the oil palm waste is such suitable material that can be utilized for making activated carbon, since they are ample and easy to find. Additionally, part of them is agricultural waste that cannot be consumed (i.e. leaves and fronds). Hence, this study aimed to analyse the potential of activated carbon from agricultural waste, namely oil palm waste, in reducing the levels of heavy metals in industrial wastewater.

Opis:: This paper discussed the treatment of Malaysian petroleum sludge by incorporating palm oil fuel ash (POFA) to replace Portland cement and quarry dust (QD) replaces sand in the solidification /stabilization (S/S) method. Preliminary studies, including chemical composition, heavy metal characterization, density test, compressive strength test, and toxicity characteristic leaching procedure (TCLP), were done to evaluate POFA and QD suitability in S/S matrices. The 10% replacement of POFA recorded a considerable density value ranging from 1500 kg/m3 to 1660 kg/m3. As for S/S matrices containing petroleum sludge, the results indicate the possibility to of encapsulating the sludge in the matrices up to 10%. The highest strength of S/S matrices with petroleum is from PS5% samples with 15.61 MPa at 28 days. The toxicity characteristic of heavy metals from the S/S matrices was below the permissible limit set by USEPA. This investigation could be an alternative solution for petroleum sludge, POFA, and QD disposal and has excellent potential for replacing other treatment approaches employed at the advanced treatment stage for petroleum refinery effluents.
