“…In terms of environmental performance benefit perspective, energy recovery and waste management are the most important criteria driving the adoption of the I4.0–CE application. Aligned with this finding, POI is currently having a serious issue with their by-product, especially palm oil mill effluent, where traditional methods have limitations that could decrease the environmental performance (Cheah et al ., 2023; Ratnasari et al ., 2022; VanderWilde et al ., 2023). Thereby, the benefit from the applied technologies through the adoption of I4.0–CE, i.e.…”

“…First, POI has received numerous criticisms worldwide and is accused of not supporting sustainable operations and using production processes that lead to heavy deforestation (Cheah et al ., 2023; Zakaria et al ., 2023). A series of anti-palm oil campaigns have been started by nongovernmental organisations (NGOs) to promote avoiding the consumption of palm oil-related products (Ratnasari et al ., 2022). These actions have attracted worldwide attention and tarnished the oil's reputation.…”

PurposeThis paper aims to contribute significantly to the empirical investigations on adopting Industry 4.0–circular economy in the Malaysian palm oil industry. The paper also aims to theorise and empirically assess a comprehensive model incorporating three aspects and 51 criteria.Design/methodology/approachA two-stage methodology is proposed using the fuzzy Delphi method and the fuzzy-based analytical network process. Twenty-seven criteria on adoptability of industry 4.0–circular economy were selected for the first-stage methodology, followed by identifying each criteria's intersection with the overall objectives.FindingsThe findings indicate that financial constraints, the lack of a collaborative I4.0–CE model, laws and policy, low management support and the training of dedicated employers in I4.0–CE-application are the top five criteria requiring critical attention from the POI.Practical implicationsThe overall sustainability advantages of the POI are identified and discussed in depth to establish criteria for industry 4.0–circular economy applications.Originality/valueThis study fills the previous research gap by theoretically explaining POI's industry 4.0 adoption–circular economy from the perspective of two underpinning theories. Due to the pressure towards sustainability, the industry must be ready to adopt industry 4.0–circular economy applications, and resources must be managed appropriately and effectively by sharing and integrating. Advanced industry 4.0 technologies and pragmatic practices such as a circular economy are needed to achieve optimal sustainable development while retaining commercial success.

“…Various treatment methods, including physical, chemical, biological, or a combination thereof, have been used to treat wastewater from this industry [116][117][118][119][120][121][122][123]. However, these methods are still seen to be less effective and less efficient because the resulting wastewater has various compositions and is difficult to classify in general [124,125].…”

Membrane separation processes are prevalent in industrial wastewater treatment because they are more effective than conventional methods at addressing global water issues. Consequently, the ideal membranes with high mechanical strength, thermal characteristics, flux, permeability, porosity, and solute removal capacity must be prepared to aid in the separation process for wastewater treatment. Rubber-based membranes have shown the potential for high mechanical properties in water separation processes to date. In addition, the excellent sustainable practice of natural fibers has attracted great attention from industrial players and researchers for the exploitation of polymer composite membranes to improve the balance between the environment and social and economic concerns. The incorporation of natural fiber in thermoplastic elastomer (TPE) as filler and pore former agent enhances the mechanical properties, and high separation efficiency characteristics of membrane composites are discussed. Furthermore, recent advancements in the fabrication technique of porous membranes affected the membrane’s structure, and the performance of wastewater treatment applications is reviewed.

“…11 Nowadays, the most commonly used pretreatment techniques include chemical pretreatment, physical pretreatment, biological pretreatment, or their combinations. 12 Acid pretreatment is a typical chemical pretreatment that can degrade most hemicellulose and remove or redistribute lignin from the lignocellulosic plant cell wall, resulting in a better enzymatic hydrolysis performance. 13 However, when the acid pretreatment is performed on bamboo residues, there is still a lot of lignin remaining in those pretreated materials.…”
