Improper management of organic industrial wastes, such as empty fruit bunch (EFB) from the palm oil industry and pressmud, i.e., a by-product of the sugar refinery industry can lead to environmental problems. This study aims to investigate the potential of pressmud and EFB as adsorbent materials in wastewater pollution removal. The chemical analysis in this study revealed that the EFB sample contained 7.30% of SiO2, 2.11% of Fe2O3, 1.91% of MgO, 28.02% of CaO, 37.59% of K2O, 1.45% of P2O5, 14.51% of Cl, 4.39% of SO3, and 2.38% of other elements. Meanwhile, the pressmud sample contained 14.32% of SiO2, 1.39% of SO3, 81.71% of CaO, 1.03% of Fe2O3, and the remaining 1.56% of other compounds. The possible adsorption capacities of pressmud and EFB were determined using the Langmuir and Freundlich isotherms. The absorption of Cd, Cr, Cu, Fe, Mn, Ni, and Zn in these samples was analyzed using the Langmuir and Freundlich isotherm models. By comparing both models, the research revealed that the Langmuir model provided a more precise description of the adsorption process for the EFB and pressmud samples and was competently compared to the Freundlich model, as indicated by the highest R2 values. The results indicate the potential of EFB and pressmud as promising reactive materials for heavy metal adsorption, and this involves recognizing possibilities for repurposing these economical and sustainable waste materials.

This research paper examines the efficacy of key success factors (CSFs) in the context of electric vehicle (EV) adoption among drivers in Malaysia. The CSFs examined in this study are infrastructure readiness (IR), perceived value pricing (PVP), and environmental conservation (ECV). The questionnaire had a respondent’s size of 253 drivers from Malaysia, with the intention of facilitating extensive and unconstrained talks including both road users and road safety specialists. A technique was developed with the aim of identifying the primary elements that contribute to the promotion of safe driving behaviour. The study's findings suggest a correlation between the utilisation of electric vehicles and the indicators of IR, PVP, and ECV. Therefore, this study provides an opportunity for experts to get insight into the effectiveness of the currently established CSFs that influence the utilisation of EV. This study aims to contribute valuable insights to the existing body of literature on the utilisation of EV by offering comprehensive information on the efficacy of CSFs and their impact on EV adoption. The findings of the study revealed a statistically significant association between the adoption of EV concepts and the driver behaviour. Many studies have been conducted pertaining to the subject matter of electric vehicles in a broad context. However, there is a dearth of comprehensive research studies that particularly examine the subject of efficiency in critical success factors pertaining to the utilisation of electric vehicles in Malaysia.
