Urban planners require an understanding of the composition as well as the spatial distribution of household solid waste (HSW) components to design policies for various wards of a city. This paper aims to study the composition as well as the spatial dependency of the HSW components generated by the wards forming Annaba city in Algeria. The results of the HSW composition have revealed the high content of the organic matters which represents 50%, the textiles with 13.6%, and the plastics with 10% of the total quantity; the rest of the composition was 5.9% of paper and paperboard, 3% of metals, and 1% of glass. Furthermore, the result of the global and the local Moran indexes calculated and mapped through the ArcGIS 10.7 software shows that there is an evident spatial dependency for almost all the HSW components. Thus, 18% of the total quantity is produced by clustered wards, which propose the segregation of individual waste components at the source as an efficient way to support the reuse, recovery, and recycling. The greenhouse gas (GHG) emissions have revealed that 60% of the emissions are the methane produced from the landfill, and 30% is due to the open burning in the air of waste.

使用 GIS 和 Moran's I 支持阿尔及利亚安纳巴市的住宅固体废物回收。

城市规划者需要了解家庭固体废物 (HSW) 成分的构成和空间分布，以设计城市各个病房的政策。本文旨在研究由形成阿尔及利亚安纳巴市的病房产生的 HSW 组件的组成和空间依赖性。HSW 组成的结果显示，有机物含量高，占总量的 50%，纺织品占 13.6%，塑料占总量的 10%；其余成分为 5.9% 的纸和纸板、3% 的金属和 1% 的玻璃。此外，通过 ArcGIS 10.7 软件计算和映射的全局和局部 Moran 指数的结果表明，几乎所有 HSW 组件都存在明显的空间依赖性。因此，总量的 18% 是由集群病房产生的，它建议在源头分离各个废物成分，作为支持再利用、回收和再循环的有效方式。温室气体（GHG）排放显示，60% 的排放是垃圾填埋场产生的甲烷，30% 是由于废物在空气中的露天燃烧。
