The aim of this work is to carry out a technical-economic analysis of an energy recovery facility (ERF) located in Sant Adrià de Besòs, Barcelona, Spain through a methodology based on social Cost-Benefit analysis, which considers the private impacts and externalities (social and environmental impacts) to determine the Total Benefit (the difference between revenues and costs) and decide if it is both operationally and economically profitable. The ERF plays an important role in Barcelona and its environs in generating energy, preventing the residual waste from being sent to landfills and therefore helping to comply with the objectives fixed by the European Commission. The key point of this work is the identification, frequency, quantification and monetary valuation of the impacts generated by the ERF, such as infrastructure costs, sale of energy, CO₂ emissions, the effects on public health, among others; providing a guide to future researchers and policymakers interested in the economic valuation of MSW management systems. Applying the methodology, it can be seen that the facility is both operationally (B_P = 9.86 €/ton) and economically (B_T = 23.97 €/ton) profitable. The results show that the ERF has high private costs, however, due to its high revenues from the sale of energy and services, the facility is operationally profitable, but with a low private benefit per ton treated. Externalities play an important role since they increase the Total Benefit and make the ERF more economic reliable.

这项工作的目的是通过基于社会成本效益分析的方法对位于西班牙巴塞罗那圣阿德里亚德贝索斯的能源回收设施（ERF）进行技术经济分析，该方法考虑了私人影响和外部性（社会和环境影响）以确定总收益（收入与成本之间的差额），并确定总收益是否在运营和经济上都是有利可图的。ERF在巴塞罗那及其周边地区在发电方面发挥着重要作用，防止残留废物被送往垃圾填埋场，因此有助于实现欧盟委员会设定的目标。这项工作的重点是对ERF产生的影响的识别，频率，量化和货币评估，例如基础设施成本，能源销售，CO₂排放物，对公共健康的影响等；为对MSW管理系统的经济价值感兴趣的未来研究人员和决策者提供指南。应用该方法，可以看出该设施在运营（B _P  = 9.86欧元/吨）和经济上（B _T  = 23.97欧元/吨）都是盈利的。结果表明，ERF具有较高的私人成本，但是，由于其从能源和服务销售中获得的高额收入，该设施可实现运营盈利，但每吨处理后的私人利益较低。外部性起着重要的作用，因为它们增加了总收益，并使ERF在经济上更加可靠。
