Mismanagement of waste fosters the proliferation of mosquitoes in the cities. In recent years, the frequency of arbovirosis epidemics has increased. In addition, the degradation of waste in open dumps emits methane, a gas with a very high global warming potential.

Despite being endowed with abundant energy resources, sub-Saharan populations have the lowest electricity access rates in the world. Yet, electricity access has an important influence on the well-being of a population: it improves access to education, communication and quality health care. In the long term, poor access to energy and electricity services hampers development prospects and the weakness of sub-Saharan power grids represents a significant cost for national economies.

Waste-to-energy plants appear as an effective means of treating these two problems as one. In August 2018, the first waste-to-energy plant on the African continent was inaugurated in Addis Ababa. Today, other sub-Saharan countries, like Kenya, seem to be interested in developing waste-to-energy solutions. Could this be the beginning of a large deployment of this technology in sub-Saharan Africa?

This note describes the challenges posed by the increase of waste production and the low progress in electrifying the continent. It provides an assessment of the advantages and limits of waste-to-energy projects as a solution. Finally, it derives lessons from a case study on the first waste-to-energy plant in Africa: the Reppie power plant in Addis Ababa.
