2019
Dunmade, I.S.
Bioenergy is touted as a viable source of stable and affordable energy in a number ofremote sub-urban centres. This study evaluates the potential social lifecycle impacts of bioenergyproduction from household wastes and agri-wastes in some African cities. The assessmentconsidered the use of rotten and unsold fruits, vegetables and other related agri-wastes fromcentral open markets in Lagos and Johannesburg as case studies. The 2009 UNEP/SETAC’ssocial lifecycle assessment (sLCA) guidelines and the associated sLCA methodological sheetsare used to evaluate the potential social impacts of bioenergy production from agri-waste onoperators/workers, the consumers, the value chain, and the local community. Preliminary resultsshowed that it will provide a lot of benefits such as alternative employment opportunities,improved profits for small businesses, waste minimization, cleaner environment and improvedcommunal health. It will also lead to improvement in energy supply, and alleviation of poverty.However, care has to be taken to protect the bio-digestion facility’s neighbourhood fromunpleasant odour, rodents and other organisms that may attempt to feed on the rotting agri-waste.The outcome of this study provides an insight to the necessity for the development of appropriatebioenergy policy/regulation and for the need to take preemptive steps to eliminate/minimizepotential negative consequences of bioenergy production on the stakeholders.
