Policy Model for Composting and Waste-to-Energy (WTE) Technology in Lubuklinggau City

This research developed a policy model for waste reduction in Lubuklinggau City through composting and waste-to-energy (WTE) technology. Using the system dynamics method, the research simulated various policy scenarios over 10 years. Results show that combining composting (40% participation) and WTE can reduce waste generation by 60% and generate 5,960 MWh/day of electrical energy. This scenario also reduces waste management costs by 8.3% compared to existing conditions. This model offers an integrative decision-making framework for local governments to optimize sustainable waste management by considering environmental, economic, and social aspects.
