| dc.description.abstract | This thesis study develops three renewable energy-based waste-to-energy multigeneration systems and examine them thermodynamically and economically. The first system uses solar-based energy and animal manure waste, and the second system utilizes waste tires with geothermal energy. Finally, the third system is an underground coal gasification system in which low-grade lignite is considered waste and used as fuel. Hydrogen, ethanol, electricity, heating, cooling, and sulfuric acid are produced for the communities in Konya in Turkey, Tuscany in Italy, and Kutahya in Turkey. All suggested systems are developed, modelled, and analyzed using thermodynamic-based sensitive simulations and software. According to the calculations, multigeneration system 2 provides the best performance results, and the overall system energy and exergy efficiencies are 71.45% and 69.87%, respectively. Integration of waste-to-energy systems with renewable energy sources leads to the prevention of waste generation and the development of more environmentally benign systems. | en |
