Biomass Energy in Malaysia: Feedstock Resources, Conversion Pathways, Supply Chains, Policy and Sustainability Perspectives

Abstract

Malaysia possesses a distinctive biomass-energy resource base because its agricultural and agro-industrial economy generates large quantities of oil-palm residues alongside other biomass streams such as forestry residues, rice residues, municipal and industrial organic wastes, bamboo and other lignocellulosic materials. The selected literature indicates that the central research problem is no longer simply whether biomass is available, but how biomass can be collected, converted, integrated, commercialised and governed in ways that deliver reliable energy and wider circular-economy value. This paper synthesizes the 100 references supplied for the study and organizes them around five interconnected dimensions: biomass-resource availability and characterization; conversion and valorisation technologies; supply-chain and system optimization; economic, environmental and social sustainability; and Malaysian policy, institutional and commercialization conditions. Attention is given to oil-palm biomass because the selected literature repeatedly identifies empty fruit bunches, trunks, fronds, fibres, shells, mill residues and palm-oil mill effluent as important components of Malaysia’s biomass landscape. The literature also covers thermochemical routes such as combustion, co-firing, gasification, pyrolysis, torrefaction and hydrothermal carbonization, biological and biochemical routes, and higher-value biorefinery products. Across these pathways, logistics, moisture and feedstock heterogeneity, conversion efficiency, capital requirements, market development, policy coordination and environmental trade-offs emerge as interconnected determinants of deployment. The review proposes an integrated framework in which resource availability feeds technology selection, technology performance affects economics and environmental outcomes, and policy and supply-chain institutions condition the ability to scale projects. The paper concludes with research priorities for Malaysia, including integrated biomass hubs, improved logistics and traceability, better techno-economic and life-cycle assessment, digitalization, flexible policy instruments, and cascading use of biomass in which energy production is balanced with higher-value material and chemical applications.
