The paper summarises a literature review into waste management practices across Africa as part of a study to assess methods to reduce carbon emissions. Research shows that the average organic content for urban Municipal Solid Waste in Africa is around 56% and its degradation is a major contributor to greenhouse gas emissions. The paper concludes that the most practical and economic way to manage waste in the majority of urban communities in Africa and therefore reduce carbon emissions is to separate waste at collection points to remove dry recyclables by door to door collection, compost the remaining biogenic carbon waste in windrows, using the maturated compost as a substitute fertilizer and dispose the remaining fossil carbon waste in controlled landfills.
本文总结了一项针对非洲各地废物管理实践的文献综述,作为评估减少碳排放方法的研究的一部分。研究表明,非洲城市固体废物的平均有机含量约为 56%,其降解是温室气体排放的主要原因。本文得出的结论是,在非洲大多数城市社区中,管理废物并因此减少碳排放的最实用和经济的方法是在收集点进行废物分类,通过上门收集去除干可回收物,将剩余的生物碳废物在垄沟中堆肥,将成熟的堆肥用作替代肥料,并将剩余的化石碳废物在受控垃圾填埋场中处理。
