“…When lower temperatures are used to incinerate the palm oil biomass, a black to dark grey OPA is produced due to the high amounts of unburned carbon [13]. Higher incineration temperatures will reduce the amounts of unburned carbon, thus producing OPA with a lighter colour and improved characteristics [14]. Therefore, every OPA is unique to its mill and there is no OPA similar to another.…”

“…As stated earlier, grinding the OPA will create a finer substance possessing a heavier specific gravity. OPA is usually ground until a median particle size of 10 μm is achieved [14]. When the OPA is of poor quality, the grinding process will not change the Table 1.…”

Oil palm ash (OPA) is a waste material produced by countries having a blooming palm oil industry. Recycling of oil palm ash is receiving increasing attention because of its huge potential in improving economic benefits and environmental awareness. Recently, it has been used as a partial replacement to cement in concrete, mortar and other cementitious materials. OPA is considered a new member of the supplementary cementing materials. Therefore, it is imperative to have a complete understanding of this material and its effects. In this chapter, a thorough literature review involving OPA will be presented. The physical and chemical properties of OPA will be listed as well as its effect when used as a partial cement replacement on the fresh state, mechanical and durability properties of a number of cementitious products. Capitalising such waste products in the production of concrete will not only benefit the recycling chain process but also produce a green product which enables the reduction of cement quantities used and also produce an energyefficient building material.

“…As an alternative to oil palm ash disposal, recycling of this waste is a good alternative. Although OPA is a relatively new pozzolanic material, many studies have endeavoured on incorporating it in producing concrete as partial cement or filler replacement [10]. However, these studies enhanced the chemical and physical properties of OPA before incorporating it in the production of concrete [10].…”

Abstract-Oil palm ash (OPA) is a waste material produced by countries having a blooming palm oil industry. Increasing palm oil production, the quantities of OPA continue to increase. However, its utilisation remains minimal and most of it is disposed of in landfills, causing environmental hazards. This study investigated the strength of foamed concrete incorporating sieved only OPA as a partial cement replacement. A foamed concrete mix of 1 part binder and 2 parts filler with a plastic density of 1450 kg/m 3 has been used. Cement is replaced by OPA at replacement levels of 25 to 65% by weight of binder. Compressive, tensile splitting and flexural strengths have been investigated at the ages of 7, 14, 28 and 56 days. A foamed concrete mix with a 25% OPA content showed superior strengths than those exhibited by the control mix, hence, producing a greener and cheaper foamed concrete.

This study aims to investigate the effect of NaOH concentration and immersion time on the activation of carbon from the oil palm frond, specifically focussing on the surface morphology and characteristics as electrodes for biobattery application. Carbonization and NaOH activation are carried out at 0.5, 1, 1.5, 2, and 2.5 M at different immersion times of 12, 18, 24, 30, and 36 hour. Moreover, the activated carbon was analyzed with a scanning electron microscope to observe the morphology, and the Brunauer–Emett–Teller (method was used to measure the surface area of activated carbon). Furthermore, another outcome of this study is the development of a prototype biobattery. At 1 M, the optimal concentration of NaOH was observed, producing the highest surface area of 336.493 m2g−1 and an electric potential of 0.653 V. On the other hand, the optimal immersion time was 30 hour with the highest surface area of 396 808 m2g−1 and an electric potential of 0.902 V.
