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.
城市规划者需要了解家庭固体废物 (HSW) 成分的组成及其空间分布,以便为城市的各个行政区设计政策。本文旨在研究阿尔及利亚安纳巴市各行政区产生的 HSW 成分的组成及其空间依赖性。HSW 组成的结果表明,有机物质含量很高,占 50%,纺织品占 13.6%,塑料占 10%;其余的组成是纸和纸板占 5.9%,金属占 3%,玻璃占 1%。此外,通过 ArcGIS 10.7 软件计算和绘制的全局和局部 Moran 指数的结果表明,几乎所有 HSW 成分都存在明显的空间依赖性。因此,18%的总量是由集聚的行政区产生的,这表明在源头对个别废物成分进行分类是支持再利用、回收和循环利用的有效方式。温室气体 (GHG) 排放表明,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焚烧造成的。
