Abstract: When investing in waste disposal projects, local government faces a critical dilemma: how to move beyond short-term cost evaluation to long-term environmental and economic benefits. Therefore, this research focuses on local government waste disposal projects, using a life cycle cost analysis to construct a comprehensive evaluation model that integrates energy, environment, and economy, and to analyze the system performance and comprehensive benefits of the proposed technological transformation plan. The results indicated that the total life cycle cost of processing one ton of tail vegetables was -97.05 Chinese Yuan (CNY), of which the internal cost was -85.04 CNY and the external environmental cost was -12.01 CNY. Sensitivity analysis revealed that government subsidies and processing benefits were the most sensitive factors affecting total costs. In terms of environmental impact, this technology route generated significant benefits across key indicators, including global warming potential and acidification potential, through biogas recovery and utilization. Its global warming potential reached -49.88 kg CO2 eq/t, significantly better than that of the original project. The energy analysis confirms that the system is a net energy producer, but the amount of biogas generated is the most sensitive parameter for its energy performance. This model effectively evaluates the long-term operational efficiency of waste disposal projects, provides a quantitative basis for local governments in project planning, process comparison, policy formulation, and improves the accuracy and sustainability of public investment.
