Alternative Energy Processes

Abstract

The thesis dissertation aimed at optimization of biodegradable wastes to improve the quality of the biomass energy sources. To achieve the aim, the problems and current approach to waste management and waste to energy areas in the developing countries were highlighted and the comparison of most common different drying methods around the world was carried out, based on moisture reduction, volume reduction and weight reduction with drying time. A sustainable approach to waste management was also proposed. Then, the optimization of the biodegradable wastes in this research work was done by oven drying and solar drying. The research work investigated the qualities of the raw biodegradable wastes before and after drying processes. Additionally, the research work highlighted the future clean energy sources derived from biodegradable wastes in order to be used directly for direct combustion and co-firing of biomass and indirectly for the preparation processes of refuse-derived fuels. Besides, the benefits from utilization of improved biodegradable wastes were also pointed out in terms of GHG emission reductions. The thesis is categorized into seven parts in order for achieving the research aim and goals. The first two parts deal with introduction and overview of the current state of the problems about renewable energy and waste management. The second three parts work on the aim of the thesis, literature review and framing of research methodology. The final two parts are related to the results and discussion regarding two different drying processes, conclusion, contribution and benefits of the research work and recommendations for the future research possibilities. This present dissertation would be the preliminary work for the future prospective of the research work for drying related to waste heat and heat supplied by solar energy and for exploring the possibilities of optimization and utilization of biodegradable wastes for a clean energy source and agriculture resource.
