Municipal solid waste management has evolved into a promising approach to climate issues and to the growing energy demand in Tunisian cities. However, energy recovery from organic waste in the Metropolis of Tunis is still complex. This is due to the city's unpredictable economy, urbanization level, and population growth rates. So far, this unpredictability has constrained access to accurate data about organic waste. This has led to slow progress in harnessing organic waste for renewable energy production. This study focuses on the conversion of the city's organic waste to biogas as a local energy supply. The potential quantity of organic waste and its theoretical energy content were estimated based on a case study in four areas in the Metropolis encompassing 12 municipalities, official records, and literature reviews. The aim of this mixed method was to enhance data quality and optimize the long‐term viability of a small‐scale biogas plant in the city. The results show that the area generates a considerable amount of organic waste (55–66%) with an annual theoretical energy content of 224.18 GWh. The yearly financial gain from the 25.5 MW biogas plant could reach 40 352 400 USD. The estimated organic waste with its considerable potential energy content represents a significant renewable energy source in the Metropolis of Tunis. © 2021 Society of Chemical Industry and John Wiley & Sons, Ltd

突尼斯城市垃圾的定性和定量表征:突尼斯大都市的案例研究

城市固体废物管理已发展成为解决气候问题和突尼斯城市日益增长的能源需求的有前途的方法。然而,在突尼斯大都市中从有机废物中回收能源仍然很复杂。这是由于该城市的经济状况不可预测,城市化水平和人口增长率所致。到目前为止,这种不可预测性限制了对有关有机废物的准确数据的访问。这导致在利用有机废物进行可再生能源生产方面进展缓慢。这项研究的重点是将城市的有机废物转化为沼气作为当地的能源供应。根据大都市四个地区的案例研究估算了有机废物的潜在数量及其理论能量含量,该案例涵盖了12个城市,官方记录和文献综述。这种混合方法的目的是提高数据质量并优化城市中小型沼气厂的长期生存能力。结果表明,该地区产生了大量的有机废物(55-66%),年理论能量含量为224.18 GWh。25.5兆瓦沼气厂的年度财务收益可能达到40352400美元。估计的有机废物具有相当大的潜在能源含量,代表了突尼斯大都市的重要可再生能源。©2021化学工业协会和John Wiley&Sons,Ltd 25.5兆瓦沼气厂的年度财务收益可能达到40352400美元。估计的有机废物具有相当大的潜在能源含量,代表了突尼斯大都市的重要可再生能源。©2021化学工业协会和John Wiley&Sons,Ltd 25.5兆瓦沼气厂的年度财务收益可能达到40352400美元。估计的有机废物具有相当大的潜在能源含量,代表了突尼斯大都市的重要可再生能源。©2021化学工业协会和John Wiley&Sons,Ltd
