Resumen

SHANE, Agabu; KAFWEMBE, Young  y  KAFWEMBE, Pride. The viability of biomethane as a future transport fuel for Zambian towns: A case study of Lusaka. J. energy South. Afr. [online]. 2018, vol.29, n.3, pp.86-95. ISSN 2413-3051.  http://dx.doi.org/10.17159/2413-3051/2017/v29i3a4893.

The objective of the study was to determine the viability of biomethane as a transport fuel for Zambian urban towns. The study revealed good potential for biomethane production and use as a transport fuel in Zambian towns, using Lusaka as a case example. There is 3.67 million m3 biomethane potential from municipal solid waste alone in Lusaka. About 3 000 tonnes of organic fertiliser would replace an equivalent amount of chemical fertiliser. The replaced chemical fertiliser would lead to about 5.816 GgCO2eqy-1 as avoided emissions. The study showed a positive net present value at the prevailing market interest rates of 28-40%; the project would become unviable at interest rates higher than that. It was estimated that the project would recover its initial investment in a maximum of two years. The research findings have closed data and information gaps in Zambia and have potential to contribute to academic research, policymaking, investments, financing and interested parties.

Palabras clave : biogas; municipal solid waste; environmental; social and economic benefits.
