Evaluation of environmental impacts of insect production for food purposes in conditions of the Czech republic by the LCA method
MUCHKA, Lukáš
The thesis deals with the evaluation of environmental impacts of insect farming for food purposes in the Czech Republic. The topic is focused on the impact category of climate change, with emphasis on Global Warming Potential (GWP for short). Environmental impacts are assessed using the Life Cycle Assessment (LCA) method. This method is based on evaluating the impact that a product has on the environment over its lifetime. This has enabled the method to assess different potential types of impacts. LCA analysis is based on the principle of "cradle to gate". The approach is based from the sourcing of raw materials to the final output gate, represented in the form of a product. One kilogram of insect product is chosen as the pro-product. For the LCA analysis, a model farm of the mealybug (Tenebrio molitor) was established. Data for this work were collected from edible insect farmers in the Czech Republic who were sent a survey. Some data were obtained from the literature. In relation to the obtained data, a calculation of the environmental burden was made. In the thesis it was found that one kilogram of insect product generates a carbon footprint of 11.87 kg CO2-eqv.

COLLECTION SCHEME OF MOBILE PHONES AND ITS IMPACT ON ENVIRONMENT
Švančarová, Markéta ; Kočí, Vladimír (advisor) ; Trecáková, Tatiana (referee)
The issue of the increasing amount of e-waste is a phenomenon of the 21st century. The amount of EoL mobile phones is growing rapidly but only a small amount is recycled. The thesis examines the environmental impacts of the Remobil project concerning the collection of phones that go to recycle. The impacts of the project are evaluated by the LCA method. Life cycle assessment is an important method of assessing the product that is part of decision-making at the international, national and local level, within the government and private sectors. The method provides complex outputs that can be comparable to other results. Modelling the impacts of the Remobil project provided a number of results. The comparison of the collecting boxes showed that the least impact on the impact category was caused by polypropylene boxes while the stainless steel boxes caused the greatest impact. The biggest influence on impact categories within the project was caused by transport, which was quite excessive due to the pilot phase of the project. It is also important to note the higher level of effort required for the per- kilogram collection of small electrical and electronic equipment (EEE) waste, such as mobile phones, compared to the collection of large EEE waste, such as washing machines. The Remobil project and recycling of...

Low-energy houses in Czech Republic
Svobodová, Jana ; Vejchodská, Eliška (advisor) ; Slavíková, Lenka (referee)
The main goal of the thesis is building up low-energy houses in the Czech Republic, especially family houses. In my thesis, I describe the history of low-energy development in the Czech Republic, a possible future and some foreign experience. I compare the standard version of development, which is demanded by Czech laws, with the low-energy version by means of SWOT and financial analysis. I try to define a life cycle assessment of a building, its environmental impact during its construction and usage by means of LCA method. Based on the findings of LCA method I would like to draw attention to the necessity to focus more on the low-energy development. The results of financial analysis shows that it is necessary to implement some instruments of environmental policy in order to support the low-energy development and project, such as tax preferences for low-energy development etc.
