Municipal solid waste management (MSWM) is one of the major environmental issues in Tunisian cities. Rapid growth in urbanization and population rates and the changes in people’s lifestyle have prompted a dramatic increase quantity and a significant shift in the composition of municipal solid waste. There is insufficient data concerning the quantities and the composition of waste streams along with the absence of a comprehensive complete overview and a wider perspective of MSWM potential that provides detailed information at region and city level. As a result, it is still impossible for the scientific community and the authorities to provide synergetic schemes to tie the problems of MSWM with how to integrate economically feasible and environmentally sustainable practices holistically. In the present study, an attempt has been made to provide a comprehensive overview of MSW, through a qualitative (compositional) and quantitative (parametric) characterization of the generated total waste generated in Tunisian cities. A 1-year research survey was conducted in seven regions in Tunisia (Great Tunis, Northeast, Northwest, Midwest, Mideast, Southwest, and Southeast) that cover the 24 provinces of the country. Collected samples revealed that the distribution of waste by region was defined by the region’s demographic, economic, and industrial status. Approaches of possibly more efficient procedures that can be undertaken to improve MSW collection are discussed. At a final stage and based on the potential of biogas calculated in the seven regions, we suggest that the scientific community and the authorities should introduce applicable schemes to valorize MSW through generating biogas as a renewable energy.

突尼斯城市固体废物的定性和定量表征以及未开发的绿色能源潜力

市政固体废物管理(MSWM)是突尼斯城市的主要环境问题之一。城市化和人口率的快速增长以及人们生活方式的改变,促使城市固体废物的数量急剧增加,组成发生了重大变化。关于废物流的数量和组成的数据不足,缺乏全面的全面概述和对MSWM潜力的更广阔视野,无法提供有关地区和城市的详细信息。结果,科学界和当局仍然无法提供协同方案来将MSWM问题与如何整体地整合经济上可行和环境上可持续的实践联系起来。在目前的研究中,试图通过对突尼斯城市产生的总废物进行定性(组成)和定量(参数)表征来提供城市生活垃圾的综合概述。在突尼斯的七个地区(大突尼斯,东北,西北,中西部,中东,西南和东南部)进行了为期1年的调查,覆盖了该国的24个省。收集的样本显示,各地区的废物分布是由该地区的人口,经济和工业状况决定的。讨论了可以采取的可能更有效的程序来改善MSW收集的方法。在最后阶段,根据在七个地区计算出的沼气潜力,
