This paper summarizes research into waste management activities and carbon emissions from territories in sub-Saharan Africa with the main objective of quantifying emission reductions (ERs) that can be gained through viable improvements to waste management in Africa. It demonstrates that data on waste and carbon emissions is poor and generally inadequate for prediction models. The paper shows that the amount of waste produced and its composition are linked to national Gross Domestic Product (GDP). Waste production per person is around half that in developed countries with a mean around 230 kg/hd/yr. Sub-Saharan territories produce waste with a biogenic carbon content of around 56% (+/-25%), which is approximately 40% greater than developed countries. This waste is disposed in uncontrolled dumps that produce large amounts of methane gas. Greenhouse gas (GHG) emissions from waste will rise with increasing urbanization and can only be controlled through funding mechanisms from developed countries.
本文总结了撒哈拉以南非洲领土的废物管理活动和碳排放研究,主要目的是量化通过可行的废物管理改善措施可以实现的减排量。研究表明,废物和碳排放数据很差,通常不足以用于预测模型。本文表明,废物产生量及其组成与国民生产总值(GDP)有关。人均废物产生量约为发达国家的一半,平均为 230 公斤/人/年。撒哈拉以南领土产生的废物具有约 56%(+/-25%)的生物源碳含量,比发达国家高出约 40%。这些废物被倾倒在不受控制的垃圾场中,产生大量甲烷气体。随着城市化的推进,废物产生的温室气体(GHG)排放将会增加,只能通过发达国家的资金机制来控制。
