| Abstract [eng] |
In many countries large quantity of waste tires is generated every year. Due to the high carbon content tires have a large energetic potential, which currently is not fully used. Other solid waste fuels with energetic potential, such as solid recovered fuels from municipal solid waste and waste water sludge, are included in the study, to be compared with energy recovery from end-of-life tires. As well a possibility to mix end-of-life tires with other fuels, in order to increase the calorific value, is estimated. To reach the target the life cycle assessment method is applied. Master thesis presents the impact assessment results of energy recovery from waste derived fuels according to three selected fuels scenarios: (a) shredded end-of-life tires, (b) solid recovered fuel produced from municipal solid waste, and (c) solid recovered fuel produced from pre-composted sewage sludge combined with biomass residues. Using the given results, most preferable energy recovery scenario is determined, by applying multi-criteria analysis method TOPSIS. Moreover in the thesis, feasible composition for selected solid fuels mixing is estimated in accordance to results, given by TOPSIS method. Environmental impact and order preference, of mixed fuel is compared to the selected main three scenarios. Overall, thesis consists of three chapters. In the first chapter literature analysis is conducted on end-of-life tires generation and waste tires management pathways. As well literature analysis includes review of other selected solid fuels: refuse derived fuel and solid recovered fuel, including solid recovered fuel from municipal solid waste and municipal waste water sludge. In the second chapter, methodology selected for the thesis development is described. Three methods are selected: life cycle assessment, theoretical calculations, multi-criteria analysis. Third chapter presents results conducted in the thesis and discussion on the results. The thesis is written in English. It consists of 68 pages, 26 figures, 26 tables and 2 appendices. 61 sources of literature have been used in the development of the thesis. |
