Kučerová, Zuzana ; Sobotka, Michal (advisor) ; Falteisková, Sabina (referee)
Legal aspects of the circular economy Abstract The diploma thesis deals with the issue of legal aspects of the circular economy. This concept is based on resource efficiency with the intention to minimize waste generation. This approach is considered to be the future of economies not only in the European Union, but also in the rest of the world. The thesis aims to provide a comprehensive overview of the circular economy and the legal background of this concept in the EU and the Czech Republic. Given that the legislation of the circular economy has so far been reflected at the EU and national level predominantly in the field of waste management, it forms a significant part of this thesis. The projection of the principles of the circular economy into the legal order as well as the future development of this concept is evaluated. Recognized advantages and disadvantages in the current circular economy legislation are formulated at the end of the thesis. Subsequently, the thesis sets recommendations for the future direction of the circular economy and for its efficiency enhancement.
Modern alternate types of sealing barriers analysis for landfills
Matoušová, Jana ; Kudrna, Zdeněk (advisor) ; Sedláček, Jaroslav (referee)
People and waste on our planet is constantly increasing, and so despite the unattractiveness topic the landfills are the current and noticeable issue. This paper deals with the standards and laws relating to landfills, from which they depend for the creation and construction. I should present an overview of the different variants of application materials to the construction of the landfill could be used, and today sealing landfills are available for engineers. But just I do not engage in alternative sealing options as well as standard which are still widely used methods of sealing landfills. To the situation in the Czech Republic stated in a global context, I give examples of coping with the landfill in other countries such as Chile, where they try to use local raw materials. What is landfill waste and security are concerned; our model may be one of our neighbours - Germany, which in this part is devoted to most extensively. Each of these options has its pros and cons. I leave at will and view of each reader to evaluate the advantages and disadvantages of each solution. It is also possible to adhere to the already proven and well used ways of depositing, in their modernized and improved form.

The second chapter considers the waste management as a branch of science activity. This branch was established in 1980s in west European countries, however, 10 years later also in the Czech Republic. The first Parliament Act on the waste management in Czechoslovakia was created in 1991. There were some mistakes and dubiousness in the Act and it was necessary to put them aside before joining the European Union in 2004. Before 2004, this Act had been changed completely two times. The Act of Czech Parliament 185/2001 Sb. went into force on 1st January 2002. Since then, it has been novelized many times according to the European law and is currently responding to the European directives. The third chapter mentions some other acts which are connected with the waste management in the Czech Republic. On the top of...

Zero Waste lifestyle mapping
Nováková, Kristýna ; Spalová, Barbora (advisor) ; Orcígr, Václav (referee)
The work explores the perception of Zero Waste lifestyle from the perspective of people who live this lifestyle. The main aims of the research are to map the perception of Zero Waste lifestyle in terms of what the lifestyle means for informants and how they perceive it. I also deal with the motivations that these people have for their lifestyle, whether it be external or internal, and I try to map the negative or positive benefits that Zero Waste brings to the lives of its followers. The work is based on qualitative research, namely on seven interviews with people who live in the Zero Waste lifestyle, with whom I conducted semi-structured interviews. Using a thematic analysis, I have identified ten categories that characterize Zero Waste lifestyle: the pursuit of change, the conversion / change of thinking, the voluntary modesty / the fight against consumerism, the saving of money, the fashion trend, the education, the spiritual / religious aspect, the fulfillment / joy / happiness, community sharing, moral contradiction. The main findings of the research are precisely the Zero Waste lifestyle characteristic that builds on authentic information taken directly from people living in this lifestyle. My findings mainly relate to characteristics of Zero Waste, how these people perceive their lifestyle...

Samšuková, Eva ; Benešová, Libuše (advisor) ; Křenková, Marcela (referee)
A landfill leachate is a chemical solution generated in the waste materials that are dumped in a landfill. According to the increasing amount of waste produced worldwide the risk that leachate water gets out of a landfill and contaminates with contained pollutants surrounding environment, e.g. nearby surface water, rises. The aim of this thesis is to evaluate the effect that leachates have to surface water in the Czech Republic. The research was built on primary data that had been obtained in several landfills in the Czech Republic. Important sources were also obtained through the secondary literature. Possible influence of leachates is also outlined by chemical calculating illustrating a hypothetical situation of leaking landfill water to a stream. My research showed that the impact of landfill water on surface water presents a great risk. It can occur during ordinary operations of the landfill operations - due to instable technical installation or due to dumping waste with a different extract conditions, but also as a consequence of extraordinary situations (e. g. storms). Surface water is mostly polluted with heavy metals, chlorides or nitrogen in variety of its forms. High concentration of organic matters is also detected by COD and BOD indicators. Exceeding legal limits threatens the whole surface...

Heuer, Dan ; Zvěřinová, Iva (advisor) ; Kyselá, Eva (referee)
Importance of Plastics and the Impacts of Plastic Waste: The Sociological View on the Possibilities of Solutions of Plastic Waste Accumulated in the Oceans Dan Heuer Abstract: The Paper deals with a question of plastic waste in the oceans. Especially, it asks about particular solutions concerning plastic waste and its effectiveness. Firstly, it is identified how human understands plastic as a material. Subsequently, negative impacts on the environment caused by plastic waste are summarized. Especially, little pieces of plastic are significant problem. Animals often mistake it for food so they can transfer harmful substances to the food chain. The main part of the work is an analysis of particular solutions. It shows that the prevention and development of bio-plastics has greater potential to solve this problem than recycling and other methods. Although there is needed to know that all of the solutions work together in cooperation so they are dependent on each other. Author presents the model of Competing functions of the environment. This system demonstrates that even though the resolving of the problem is not achievable in short period, it would be very positive that humankind is trying to fight against the stream of plastic waste to ocean. Therefore establish the balance among utility possibilities which...
