“…Due to the enormous volume of this residue, new alternatives for its disposal have been sought. The main reuse is in the crops as a source of organic matter [15,16] or as biomass to obtain electric energy or feed the boilers in the process of oil extraction [17,18], resulting in the production of large amounts of ash (about 5% by mass), which are normally disposed in landfills [19,20].…”

“…The use of palm oil empty fruit bunch ash (POEFBA) in cementitious compounds is still little explored [18,24]. Most of the studies in the field are related to the use of ash resulting from the burning of palm oil fiber, shell and kernel due to the great use of these by-products as biomass for boiler feed in the leading production countries such as Malaysia and Thailand [6,17,19,[25][26][27]. In this way, this work sought to evaluate the mortar properties obtained with the partial substitution of Portland cement by POEFBA, obtained in oil palm extraction industry in the State of Bahia, Brazil, in contents of 5%, 10% and 15% in mass.…”

Currently, palm oil is a leader in production and consumption among commercial edible oils, with a growing world production that exceeds 66 million tons per year. It is estimated that the generation of residues from the burning of palm oil empty fruit bunches as fuel in the boilers corresponds to 5% in mass of the total of oil extracted. This work evaluated the mechanical properties resulting from the use of the empty fruit bunch ashes as a partial substitute of Portland cement in mortars in different contents in 1:3 and 1:6 mixes. Mortars obtained with the use of ash presented greater deformability, implying greater workability. The results obtained pointed to potential use of the ash as filler in mortars without loss on compressive strength for contents up to 10% in the 1:3 mix and 5% in the 1:6 mix. It was observed an increase in the void index and the water absorption capacity, with a proportional reduction of the flexural strength.

“…Malaysia alone generates about 4 million tons of OPA annually. OPA is siliceous in nature and this has drawn the interest of researchers to look for its various potential applications such as cement replacement material, adsorbent for the removal of zinc from aqueous solution, and flue gas desulphurization [4][5][6]. Still, most of the OPA generated ends up in landfill causing environmental problems.…”

Oil palm ash (OPA) is an agro-industry waste and it has disposable problems. In the present study, an effort was made for value addition to OPA by incorporating it as a micro-filler in different concentration (0, 10, 20, 30, 40, and 50%) and sizes (100, 200, and 300 mesh size particles) in the epoxy matrix. Prepared micro OPA was having a crystallinity index of 65.4%, high inorganic elements, and smooth surface morphology. Fabricated composites had higher void content as compared to neat epoxy matrix. Mechanical properties of fabricated composites had a maximum value at 30% loading of 300 mesh-size filler due to its low void content and size as compared to filler of 100 and 200 mesh size. Further increase in the concentration of OPA filler after 30 wt% of loading leads to the agglomeration of OPA microparticles and thereby resulted in the reduction of mechanical characteristics such as tensile strength, tensile modulus, flexural strength and flexural modulus of the composites. However, elongation at break decreased with increase in filler content at all percentage. Thermal stability and char residue percentage of composite increased with the concentration of filler at all percentage. Surface morphology of composite showed that OPA incorporation lead towards its roughness and cracks were originated from the site of OPA embedded in the epoxy matrix. The 300 meshsize particles were having the best effect on composite as compared to 100 and 200 mesh-size filler.

“…Currently, researchers are investigating on cement replacement used in S/S matrices (Li, 2001). Various researchers have been carried out using palm oil fuel ash and quarry dust in partial cement and sand replacement in S/S method which resulted as a good binder due to its abundance and high pozzolanic characteristics (Thomas, 2017).…”

In recent years, petroleum industry has generated huge amount of petroleum sludge. There are many types of treatment method in petroleum sludge (PS) and one of the treatments that arise the attention to treat the sludge is solidification/stabilization (S/S) method as it immobilizes and stabilizes the hazardous substances within a solid matrices. The main objectives of this research are to formulate the correct mixture of PS in S/S matrices and to stimulate the long-term leaching behaviour of S/S matrices in PS treatment with palm oil fuel ash (POFA) and quarry dust (QD) as partial cement and sand replacement respectively. The characterization of PS, POFA and QD were done by using X-Ray Fluorescence (XRF). Furthermore, different percentages of petroleum sludge (control, 0%, 5%, 10%, 20%, 30%) were incorporated with fixed 10% of POFA and 20% of QD replacement into S/S matrices. This research also includes a comparison of two different leaching test parameters such as liquid to surface area ratio, pH, and type of leaching solution on the samples. The leaching test conducted namely are Semi-Dynamic Leaching procedure (SDLP) and Static Leaching Test (SLT). The leachability results from SDLP and SLT indicated that all concentration for nine (9) heavy metals were below the permissible limit set by United States Environmental Protection Agency (USEPA, 1996) standards. In addition, the S/S effectiveness was evaluated by measuring effective diffusion coefficients (De) and leachability index (Lx). Results of S/S treatment shown that De values were lower and Lx values were higher than 8 thus the S/S can be disposed in sanitary landfill. As a conclusion, the results for the leaching behaviour of PS up to 10% incorporated with 10% of POFA replacement in cement and 20% of QD replacement in sand demonstrated minimum leaching of the heavy metals from S/S matrices. This indicated that S/S method could be an alternative disposal method for PS and has potential for replacing other
