THEORETICAL PREDICTION OF BIOGAS FROM SOLID WASTE GENERATED IN UNIVERSITY OF LAGOS, NIGERIA

The management of solid waste especially in a developing country like Nigeria is a challenge. There is a possibility of biogas recovery from solid waste generation. This study was carried out to predict the amount of biogas and methane from solid waste generated in University of Lagos, Nigeria. The composition of solid waste generated in University of Lagos was used to establish the chemical formulas for the solid waste. The model of Buswell and Muller was used to generate the reaction for the solid waste from which the theoretical and actual amount of biogas and methane were predicted. The chemical formulas with and without sulphur for organic portion of solid waste generated in University were C187H377O137N7S and C26.71H53.88O19.57N respectively. The theoretical and actual amount of biogas were found to be 0.847 and 0.678 m3/kg respectively while that of methane were 0.469 and 0.375 m3/kg respectively. The biogas from solid waste generated in University of Lagos can be used for domestic purposes and electricity generation to promote energy security and sustainability.
