Analysis and assessment of integrated waste-to-energy systems based on plastic wastes for multigeneration
MetadataShow full item record
This thesis proposes three wastes to energy multigeneration systems that are based on plastic wastes. The three systems are coupled with renewable energy resources like solar energy, geothermal energy, and wind turbine energy. The three systems are designed to convert plastic waste into five useful outputs of electric power, heating, fresh water, domestic hot water, and hydrogen. The proposed locations for the three systems are Cordoba, Spain for the first multigeneration system, Kakkonda, Japan for the second multigeneration system and Tarfaya, Morocco for the third system. The systems are analyzed thermodynamically and studied parametrically to identify optimum operating conditions. Energy and exergy analyses are performed to identify the efficiency of each system. According to the findings, the first system has the highest overall energy efficiency at 71.43%, while the second system has the highest exergy destruction rate 8,141.58 kW at the gasifier.
