Water issues, especially water scarcity and water pollution, have been affecting human lives and economic developments for a long time. Global climate changes exacerbate the probability and frequency of extreme events such as water scarcity and severe floods. The increasing irregular water supply and water pollution issues require more advanced water resources assessment methodologies to guide practical water use and management. This thesis presents the extended methods for water quantity-quality assessment and water-related energy consumption and emissions. Three major methodologies are proposed based on the Water Footprint concept and Water Pinch Analysis frameworks to assess the quantity and quality impact of water use. These methods are also demonstrated with numerical and empirical case studies targeting regional and industrial water resource assessment and optimisation. In addition, the Water-Energy Nexus is discussed to investigate the water issues from a broader perspective. An initial assessment of the water-related energy and GHG emissions of the seawater desalination industries is carried out. The studies in this thesis convey several contributions to the current water resource assessment methodologies. The proposed Water Availability Footprint made an initial effort to cover the water quality degradation impact into the existing water scarcity assessment frameworks, which was not addressed previously. The second contribution of this work is the proposal of the Quantitative-Qualitative Water Footprint (QQWFP), where a cost-based water footprint is defined and determined with the total cost of water consumption and removing contaminants generated during the water use process. The cost-based water footprint provides results which are more intuitive for water managers and the public and can better guide industrial and regional water use and management. The third contribution is the development of the Water Scarcity Pinch Analysis (WSPA), which applied the Water Pinch Analysis at a macro level for regional water use assessment and optimisation. All three proposed methods determine the water use impact in terms of water quantity and quality, and the QQWFP and WSPA also cover the impact of multiple contaminants. In addition to seeking solutions, this thesis also proposes potential directions for future investigations. Significant potential aspects to be further discussed include 1) a more advanced quantification method of the impact of multiple contaminants, and 2) an implementation and economic feasibility analysis of the WSPA and QQWFP with localised data, which seek a customised solution to regional and industrial water use optimisation.

Waste composition analysis as a support mechanism for circular economics
Halamíček, Samuel ; Varbanov, Petar Sabev (oponent) ; Fan, Yee Van (vedoucí práce)
The diploma thesis focuses on the application of waste composition analysis to facilitate the transition of waste management towards a circular economy, thereby promoting sustainable development. The first part of the thesis covers the introduction to the topic of waste management and the circular economy, followed by an exploration of the techniques and tools for performing waste composition analysis. The second part presents the detailed analysis to identify the waste composition at the first and third levels with a focus on municipal waste. The waste composition analysis is based on a certified methodology that was created as part of the TIRSMZP719 project. The data management was conducted primarily by Visual Basic for Application (VBA) programming. The results of the waste composition analysis are illustrated through diagrams, allowing for the identification of possible trends and waste stream variation across the studied time of municipal solid waste. The applicability of the tool in suggesting suitable waste treatment and recovery implementations based on the identified waste composition is demonstrated through a case study of Brno municipality. The analysis reveals that biowaste comprises the highest proportion (23.17%) of municipal solid waste, with food waste identified as the main waste composition at the third level assessment. This finding proposes high feasibility and potential for biogas production. The waste treatment solution for the other waste composition is also suggested in this thesis. Such assessment is important and could lead to the potential reduction of municipal solid waste by approximately 40% through the enabling of targeted strategies for resource recovery. This finding is very important, because the overall designed conception can respond to this separation potential, which is linked to stated goals or other obligations related to the goals of the Waste Management Plan of the Czech Republic. The proposed assessment emphasizes the proposed goals and shows the potential for their fulfilment.
