“…Consequently, OPEFB is often either left to decompose naturally or utilized for mulching, serving as a soil conditioner. However, these practices can lead to pollution and pest attraction since OPEFB breaks down slowly owing to its high carbon-to-nitrogen ratio [4]. To address this, there is a growing interest in converting OPEFB into biogas, aligning with Malaysia's National Renewable Energy Policy and Action Plan to increase biogas production capacity by 2030 [5].…”

The palm oil industry plays a vital role in Malaysia, but it generates substantial amounts of biomass waste, which, if not properly managed, can lead to environmental pollution. Among these waste products, oil palm empty fruit bunch (OPEFB) is the most abundant and underutilized, being generated daily without any commercial value. The aim is to efficiently convert OPEFB into fermentable sugars for improved biogas production. Nevertheless, the challenge lies in efficiently degrading OPEFB within a short timeframe before fermentation into biogas can occur. This study aims to explore the potential of hydrothermal pre-treatment as a means to enhance biogas production from OPEFB. The pre-treatment process was optimized by varying reaction temperatures (100 to 250°C), and reaction times (10 to 40 minutes). The main objective was to maximize the total soluble sugar yield, a crucial precursor for efficient biogas production. The optimal conditions for hydrothermal pre-treatment are identified at a temperature of 175°C and a reaction time of 20 minutes, resulting in a yield of 49.2 mg of glucose per gram of OPEFB. Subsequent anaerobic co-digestion of the treated OPEFB with digested sludge increased methane yield to 100.53 ml/g-VS, representing a remarkable 392% increase compared to the low 20.44 ml/g-VS produced by untreated OPEFB. Nonetheless, elevated pre-treatment temperatures (200°C and above) led to reduced biogas production due to inhibitory compounds. This study demonstrates the effectiveness of hydrothermal pre-treatment as a low-temperature, green technology for enhancing OPEFB-based biogas production, contributing to Malaysia's renewable energy goals. Future research should focus on scale-up and validation of this integrated process.

“…A significant quantity of biomass, specifically the empty fruit bunch and palm oil mill effluents (POMEs), remains uncollected in the mills. The study conducted by [17] reveals that the deterioration of empty fruit bunches (EFBs) leads to the emission of non-carbon dioxide greenhouse gases into the atmosphere. In addition to that, there was a study that was reported in 2022 on the Air Pollution Index (API) in Sabah where the data for this study had been collected between the years of 2010 and 2016.…”

The inability to effectively manage waste has evolved into one of the most significant challenges faced in oil palm plantations, and this failure has had an impact on the operations within the plantation. This study examines how attitudes (ATT), subjective norms (SN), and perceived behavioural control (PBC) affect both behavioural intention (BI) and sustainable waste management behaviour (SWMB) in the palm oil mills of Sabah, Malaysia. The theory of planned behaviour (TPB) serves as the primary theory in this research, which uses a conceptual framework. Distributed questionnaires to the top management of 133 oil palm mills were used to gather the data, and then they were processed using Smart-PLS V4. This research found out that SN and PBC have an influence on individuals’ BI and SWMB adaptations in Sabah’s oil palm mills. The SN was shown to have the strongest association between the SWMB and BI. However, attitudes resulted in no impact on either the intention to engage in sustainable waste management behaviour or on the actions themselves. Ultimately, the findings of this study will give a framework for the governance of palm oil waste in Malaysia by contributing to the development of a legislative and regulatory framework in this area that is more effective.

“…A significant amount of biomass, notably the empty fruit bunch and palm oil mill effluents (POME), are still left unharvested in the mills. Due to the open decomposition of empty fruit bunch (EFB) that generates non-CO 2 greenhouse gases into the atmosphere, as reported by Saritpongteeraka et al (2022). Furthermore, it was said that palm oil production is related to a significant quantity of biomass, and the key difficulty is the high cost of disposal owing to the enormous volume of EFB that does not have an appealing market value (Abdullah et al, 2013).…”

With the ever‐increasing danger of climate change, power plants are shifting from polluting fossil fuels to sustainable bioenergy fuels. As Malaysia continues to pledge to decrease glasshouse gas (GHG) emissions, quick and dramatic action should resolve the reliance on fossil fuel power plants. Furthermore, the coal‐fired power station is Malaysia's biggest supplier of energy and the final power plant to be decommissioned. In Malaysia, a significant portion of palm oil biomass has the potential to replace coal in the generation of renewable energy power. However, the deployment of palm oil biomass as a renewable energy source has not been fully achieved. Furthermore, the surplus of unutilized biomass from the palm oil milling process has emerged as the key talking point leading to environmental concerns. As estimated, this palm oil biomass can generate approximately 5000 MW of electricity under 40% of operation efficiency. This significant power potential has the ability to replace Malaysia's yearly reliance on coal. Nonetheless, the limitations of technological stability, budgetary constraints, and other government policy concerns have prevented the potentials from being fulfilled. This necessitates an integrated framework that synergizes the decarbonization drive in order to realize the primary advantages of energy renewability and carbon neutrality. Among the suggested actions to decarbonize the power generating sector is an integrated scheme of palm oil production, biogas plant for electricity and steam generation, and biofuel pellet manufacture. This review provides an in‐depth overview of palm oil biomass for Malaysian power production decarbonization.
