Kompostování jako způsob zpracování potravinových odpadů
Tóthová, Katarína
This master thesis focuses on waste and waste management, with an emphasis on biodegradable waste, specifically food waste. The thesis discusses the legislative regulations in the Czech Republic and the European Union. Among other things, composting is considered as a possible solution to the waste generated. The practical part of the thesis evaluates the final product of composters to which additives have been added to reduce odour. The additives were added to the waste collection bins. The added additives include citric acid, tea tree oil and lime. In addition, compost without additives was also evaluated as a control sample. The composting lasted for 12 weeks. The pH and electrical conductivity were evaluated throughout the composting process and then the final product, i.e. the mature compost, was evaluated using phytotoxicity tests. The results showed that although the compost met the required pH and electrical conductivity values, it was found to be highly toxic. Even at a compost concentration of 10%, inhibition of plant root growth was shown, making the compost inapplicable to soil. Furthermore, even compost without additives was found to be toxic, with the cause of toxicity apparently being the waste used and not the additives. In view of these results, further investigation of additives is still needed. This thesis contributes to a better understanding of composting as a way of treating food waste and shows the importance of systematic monitoring of the quality of the final product.

Skladba gastronomického odpadu ve vybraných provozovnách Jihomoravského kraje
Vojáčková, Eliška
The aim of the work is to obtain data from selected establishments in the South Moravian Region and to evaluate the obtained data. In the theoretical part, the legislation concerning the collection and processing of gastronomic waste is researched. Furthermore, the collection procedures and the containers into which the waste is placed, as well as the collection and the technology used for this type of waste are presented. The last point is the treatment of catering waste either aerobically or anaerobically - that is, composting or in biogas plants. The individual types of treatment are described in terms of the process, the influencing factors and the occurrence in the Czech Republic. The practical part contains data obtained in selected plants in the South Moravian Region. These data were obtained by weighing the waste for three months during the preparation and consumption of food. The observed data were evaluated and compared with each other with subsequent discussion in the establishments where the waste goes next.

Using projects with environmental themes in pre-school education
PRACHAŘOVÁ, Markéta
The bachleor thesis is focused on an environmentally friendly way of life in connection with waste. The aim of the work is to create and apply educational activities that tend to elementary awareness of this topic by childern of preschool age. The theoretical part of thesis is devoted to the definition of terms related to the damage and protection of environment, sustainable development and environmental education of childern. There are also mentioned curricular documents related to environmental education and projects focused on the issue of waste, which can be used by kindergartens. In the practical part are introduced teaching activities implemented in accordance with the tematic plan. Main target of this plane is to create awareness about the possibilities how to protect nature from the increased amount of waste and lead childern to a gentle approach to the nature. The activities are divided into two blocks. The first block is focused on sorted waste, recykling and upcykling. The second block is concentrated on the use of biowaste and composting in the kindergarten. All activities are adapted to the age of childern. Each of the listed activity includes a detailed description, own implementation and reflection.

Balanced approach in waste management
Přibyl, Zdeněk ; Kropáč, Jiří (referee) ; Gregor, Jiří (advisor)
The thesis deals with the development of a balancing tool for the monitoring of selected waste streams, the related legislation, and the development of techno-economic models for waste treatment plants. In the research part of the thesis, the legislation setting the conditions of waste management is presented, the authorised packaging company EKO-KOM is introduced, including the remuneration calculator created. The practical part of the thesis describes the developed sub-tools and the balancing tool itself, which is the focus of the thesis. Subsequently, the waste stream is analysed and the waste treatment at the reference site is evaluated. Based on the processed data, the practical part leads to the development of techno-economic designs for the plastics processing plant and the energy transition.

Landfilling as one of the causes of climate change
Knopp, Lubomír ; Balgová, Zuzana (referee) ; Hrabová, Kristýna (advisor)
This thesis deals with municipal waste landfilling. The aim of the thesis was to map the current situation of municipal waste management, to present the European and Czech strategies in the field of waste management and to evaluate the risks associated with landfilling. The thesis examines all the consequences and risks of landfilling. The thesis then looks at the difference objectives and action plans of the European Union and the Czech Republic in the field of waste management. Finally, educational tools for waste prevention in the Šternberk micro-region are presented.
