| Opis: | Waste management is a global problem, as waste production continues to rise, and the methods used today, such as landfilling and incineration, can cause many environmental issues. Waste gasification, among other technologies, is a promising alternative since waste is turned into useful energy resources and reduces emissions with the formation of syngas. Thus, this thesis investigated the potential of waste gasification systems in sustainable waste management and circular economy. Focusing on its energy and economic potential, modeling methods were used to recreate real-world systems, with the goal of properly estimating the true sustainability potential of the waste gasification systems. Biomass gasification was evaluated through thorough thermodynamics and economic analysis. Although the initial calculations failed to provide positive results by showing the energy of 54 MJ, instead of the expected energy release, further analysis with the optimized conditions and different assumptions, provided more accurate results. By increasing the share of oxidized CO from 10% to 25%, and reducing the wet material from 35% to 10%, total released heat was estimated to be −148.9 MJ. With the right assumptions, the gasification process was proved to provide good energy values necessary for the sustainability of such a process. Additionally, the financial analysis produced a high Net Present Value (NPV) of EUR 3,434,411.46, Internal Rate of Return (IRR) of 21.81%, and a short payback period (PP) of 4.48 years, hence proving the strong economic potential and financial strength of such technology. Therefore, biomass waste gasification was concluded to be a positive investment opportunity with valuable long-term economic benefits, while still providing good energy balance. |
