Optimization of Biogas Production from Municipal Solid Waste Using Response Surface Methodology (Published)

This study investigated the development and simulation of CSTR for biogas production from municipal solid waste. The factors affecting biogas production studied were pH, retention time and organic loading rate. Optimization of the parameters were done using Minitab and desirability optimization function shows that percentage error between predicted optimal responses and actual optimal responses is less than 2%, making the desirability function adequate in optimizing the factors affecting the yield of biogas from MSW. Under the process of continuous stirring of the Bio-digester tank and optimization of the process conditions, the digestion of the substrates subjected at different process parameters with these conditions averagely gave biogas yield of 67.588mL biogas/mg. This showed an increase in the production of Bio-gas.

Bioethanol Production from Municipal Solid Waste: Technical Overview, Progress and Challenges (Published)

Due to the rapid growth in population and industrialization coupled with the adverse side effects from usage of fossil fuels, there is a high demand for renewable fuel especially ethanol which is environmentally friendly and can be used as substitute for premium motor spirit. Conventional crops such as corn and sugarcane are unable to meet the global demand of bioethanol production due to their primary value of food and feed. Therefore sugar, starch and lignocellulosic materials from municipal solid waste stream are attractive feedstocks for bioethanol production. Agricultural wastes from municipal solid waste stream are cost effective, sustainable, addresses environmental pollution and create wealth and energy. Bioethanol production from wastes could be promising, however, the processes has several challenges and limitations such as feedstock sourcing and finance. This paper gives an overview, the technicality, challenges and the progress for bioethanol production from municipal solid waste.
