Abstract

The scope of this work follows up on the previous part A, which focuses on the energy use of waste through combustion for the benefit of the proposed Opatovice waste-to-energy (WtE) power plant concept. Part B discusses the application of gasification technology to the WtE concept. Different technologies, including plasma gasification and pyrolysis, and their potential for converting mixed municipal waste into energy are explored. This work also highlights the challenges and considerations in implementing these technologies, such as the need for the producer gases to be cleaned towards the quality level of natural gas combustion and the importance of waste homogeneity. The environmental impact of these technologies is also discussed, with a focus on emissions and waste management. This study also evaluates the potential consequences of not implementing any advanced technologies, such as continued reliance on fossil fuels and increased landfilling rate, along with other environmental and energy supply considerations. Gasification technologies offer opportunities to reduce landfilling and achieve partial energy independence. However, the implementation of such a technology is dependent on various factors, including the availability of alternative fuels and the capacity of natural gas supplies. This study emphasises the need for further research and development in this area.
