[Display omitted] • POME bioenergy recovery can meet world bioenergy needs. • Integrated process can boost POME bioenergy but needs urgent scale-up research. • Advanced and cost-effective methods are needed for biogas upgrading and storage. • The technoeconomic feasibility of POME-to-bioenergy must be improved to attract investors. • The remaining challenges and recommendations towards advancement are laid out. Reusing palm oil mill effluent (POME) to generate bioenergy effectively promotes a circular economy in wastewater treatment, cleaner production, and renewable energy. Traditional methods like open-air ponds and tanks are ineffective for significant biogas production and energy recovery. Additionally, conventional biogas upgrading experienced challenges in efficiency and commercialisation. Hence, introducing advanced technologies from upstream to downstream processes is indispensable to realise the industrialisation and commercialisation of biogas from POME. This review presents a comprehensive comparative analysis of bioenergy production from POME using covered lagoon, single, and integrated bioreactor operation strategies. In addition, the challenges and benefits of biogas upgrading, compression, and storage methods are also discussed and reviewed. This review also evaluates the techno-economic and environmental impacts of biogas generation and processing from POME. Finally, this review proposes strategies for addressing remaining challenges and advancing the field. [ABSTRACT FROM AUTHOR]
