Application of Analytical Hierarchy Process (AHP) to Assess Bio and ThermalConversion Technology Options for Organic Solid Waste Management
Year: 2026
Type: article
Abstract: Indonesia is increasingly challenged by the management of organic solid waste, especially in Bali Province, where organic waste accounts for about 68% of the total municipal waste produced. The current waste management strategies mainly depend on landfilling and basic composting techniques, which are inadequate to mitigate the environmental and socio-economic effects. This research utilizes the Analytical Hierarchy Process (AHP) to systematically assess and prioritize eight bioconversion and thermal-conversion technologies for managing organic waste in Bali. The evaluation considers four main criteria, environmental, social, technical, and economic, along with their sub-criteria, based on expert opinions and literature review. The results reveal that bioconversion technologies, particularly composting, black soldier fly (BSF) processing, and eco-enzyme production, are the most appropriate choices, as they offer high community acceptance, reduced greenhouse gas emissions, and better compatibility with local waste characteristics and socio-economic conditions. Thermal technologies like incineration and gasification are less favored due to their higher environmental risks and capital expenses. The findings offer a comprehensive decision-support framework for policymakers and practitioners to create sustainable organic waste management strategies tailored to Indonesia’s context.
