Waste management system sustainability
Bravený, Adam ; Touš, Michal (referee) ; Pavlas, Martin (advisor)
The thesis proposes a new approach to assess sustainability of waste management systems. In the first part current mixed municipal waste (MSW) management system of the Czech republic is reviewed and promising MSW treatment techniques are introduced. In the second part a summary of literature on Life Cycle Assessment (LCA) approach to assess sustainability of MSW systems is provided. A new sustainability assessment model is proposed by implementing LCA to a current tool called NERUDA used to optimize waste management costing. It is demonstrated how to connect these two concepts in order to aquire a powerful tool for sustainability assessment.

Odpadové hospodářství v obci Čebín
Brychtová, Iva
This diploma thesis deal with the issue of waste management in the municipality of Čebín. The introductory part is dedicated to a literature search in the field of waste management. The aim of the thesis is to comprehensively describe the waste management system in the selected municipality before and after the introduction of the new waste management system. This system is supposed to achieve a better sorting of waste from the total amount of municipal waste, which is currently very low at 14 %. On the basis of own observation since the introduction of the new system for 1 year to evaluate the shortcomings and advantages of the new system, to compare the sorting of the municipality over the last 10 years, to prepare a SWOT analysis on the waste management system and this analysis to proceceed after that on the base of the result evaluate the data from the citizens of the selected municipality by questionnaire survey. The data obtained will also be used to develop a proposal and recommendations for new measures in the waste management of the municipality of Čebín. By the newly introduced system was found to increase the sorting rate of the municipality. However, the municipality's costs for waste management are higher and the municipality will probably have to increase the local charge for the waste management system in the future. This unpopular step can caused to dissatisfaction among citizens and their motivation to sort waste is likely to become less and less.

Construction and demolition waste
Šmídová, Denisa ; Výskala, Miloslav (referee) ; Aigel, Petr (advisor)
This bachelor thesis deals with the analysis of the amount of construction and demolition waste on two-storey flat-roofed houses. It is based on legislation that comes into force this year. The data processing methodology proposes a procedure to determine the amount of demolition waste on a construction site. The breakdown of waste types is proposed according to the expected acceptance of this waste in recycling centres or landfills. The budget for the new construction of the building is used to analyse this quantity. The identified quantity of construction and demolition waste is related to the floor area and the built-up area of the building. The analysis of the amount of waste in the demolition of a building is complemented by a practical example, including a comparison of the current methodology.

Legal regulation of construction waste management in the context of the circular economy
Prucek, Jan ; Sobotka, Michal (advisor) ; Fabšíková, Tereza (referee)
The thesis deals with the legal regulation of construction and demolition waste as a specific group of waste, especially with regard to its placement in the context of the concept of circular economy. In addition to the current state of this topic, the historical development of the legislation is presented, as well as the individual methods of construction waste management and related institutes and entities governed by this legislation are defined. The thesis has an introduction, four chapters, each of which presents the individual topics in detail, and a conclusion. The first chapter introduces the concept of circular economy, its development and legal anchorage, as well as its basic principles. The chapter also defines the concept of waste management, going beyond this to present its hierarchy and basic objectives. The second chapter analyses the development of waste legislation with a focus on construction and demolition waste and in addition presents the strategic documents of waste management, which are the Waste Management Plans. The third chapter is devoted to the object and entities of the legislation, i.e. construction and demolition waste, and waste in general, and the persons involved in waste management. For construction and demolition waste, the emphasis is on its definition and...

Biodegradable plastics in the waste management system
Šalanda, Pavel ; Innemanová, Petra (advisor) ; Hnátková, Tereza (referee)
Plastics are currently widely used material. Their disadvantage is bad environmental sustainability. Therefore, since the 1970s new materials have been searched for that would be able to replace the old ones. The most successful is the production of so-called biodegradable plastics (or in general bioplastics). We get them mainly from plant substrates, they have great diversity (300 types) and quite different properties. Currently they have been implemented into practice but their production does not exceed 1% of total plastic production so far. The thesis deals with the question how to handle these materials at the end of their life. In the first part the behaviour of biodegradable plastics in particular end devices and their consequences are outlined. The objective is to choose the best possible disposal option. Comparing recycling with conventional plastics, composting, anaerobic digestion, incineration or landfilling, the best option is to lead their waste stream to energy recovery facilities. Several bioplastics degrade well in aerobic conditions of composting plants or anaerobic reactors of biogas plants. However, surface disposal is in a universal way is possible due to different properties only by the burning process. The second, final part deals with the optimization of the operation of...
