Solid Organic Wastes into Energy
Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
The aim of this thesis work is to give the overall view on technologies already used tomanage solid organic wastes in order to produce different kinds of energy, and somedevelopment possibilities in this field. In the times of increased concern in the climatechange, renewable energy sources, reduction of carbon dioxide emissions and proper wastemanagement, the aspect of using generated organic wastes to produce efficient and “clean”energy seems more and more interesting.Performing careful analysis of the subject, taking into consideration all possible aspectsdeciding whether the discussed technology is sustainable or not, this reports objective is toshow the relevance and importance of making these sustainable technologies used on alarger scale. This study shows the importance of development in the field of technologytogether with strong governmental policy action. This paper highlights the high potential inthis kind of energy generation, reducing the need of usage of fossil fuels and need forcontinuous improvement with major increase in research and investments. Important inshowing the clear view on presented technologies, is to establish strict boundaries of thesystems. In this thesis, I will focus on the technology itself, excluding the impact of stepstaken before and after the process, like transportation of the feedstock into the plant orways of delivery to the customers. The system boundaries will be limited to the emissions,performance and efficiency of the method mentioned, however in some cases, it will beextended to product quality assessment and usage efficiency.The structure of this thesis work will help the reader to draw some building conclusions. Firstpart contains an introduction, explaining the need of introduction of technologies whichwould reduce the use of fossil fuels. It also presents different types of solid organic wastesand presents brief description of possible treatment methods, accompanied with energyproduction. Next part gives the detailed description of methods like gasification, biologicaltreatment methods, ethanol production using municipal solid wastes and many others. Thisis followed by analysis according to sustainability indicators, social, economical andenvironmental aspects, which will give a field for personal discussion and some criticalanalysis.
