Abstract:

The growing need for sustainable energy sources has fuelled interest in the generation of biogas from organic waste. In this study, the researcher examined the optimization of biogas production from organic waste at Olusosun Landfill in Lagos State, Nigeria, where waste disposal is still a serious issue. Nigeria, like many other developing countries, is facing a waste management issue due to inadequate trash collection, disposal, and recycling facilities. The growing population and urbanization have resulted in vast volumes of trash, raising health and environmental issues. The research aim was to examine biogas as a way of managing waste at Olusosun Landfill, Lagos and to evaluate the optimal technology of the production of biogas in developing countries. Data was collected based on the response from the respondents whose opinion was sampled. 300 targeted questionnaires were sent across while 222 were retrieved as well based on the investigation conducted. The responses were verified, sorted, classified, and analyzed. Biogas Production is a qualitative dependent variable: hence, the model for the estimation of the logistic regression dependent variable was adopted. Analysis of Variance (ANOVA) was used to analyze the relationship between the variables under this study to determine if there was a significant difference between the research questions. Binomial logistic regression estimates the probability of having Biogas Production from the municipal solid waste which is measured if greater than or equal to 0.5, it returns positive which statistics classifies the event as occurring. The coefficient of determination R2 which is 0.030 and signify that 3.0% of the total variation in the Biogas Production is explained by the regression equation Logit(πi) = β0 + β1X1i + β2X2i + β3X3i which indicates that the prediction made on Biogas Production is reliable at 3.0% percent. This shows that biogas production is possible from municipal solid waste. The study finds that biogas production reduces deforestation, ecological imbalance, climate change, and environmental pollution, in which ecological imbalance contributed significantly to biogas production. This research comes in a right time when the world has high attention on climate and emissions caused mainly by energy demand and use. The success of this research would benefit the environment, economy, and sustainable development of countries around the world. There is still a long way to go on the path to perfection, but certainly the steps that have already been taken have been significant.
