ABSTRACT
The present work aimed to evaluate the efficiency of the municipal solid waste (MSW) management system in Kuito, Angola, using an efficiency index (MSWEI) adapted to African conditions. Four dimensions constitute MSWEI: governance; gravimetry and logistics; sorting, valuation, and composting; and final disposal. The MSWEI reached 37.6%, corresponding to an inadequate MSW management system. The main MSW management guidelines include the development of environmental education; selective collection, sorting of dry recyclable materials and shipping to the capital Luanda; composting of the organic waste; creation of an inter-municipality consortium to share the costs of a landfill.
