	Biodegradabilní materiály a jejich vliv na životní prostředí Mrkvičková, Klára Bachelors thesis is focused on biodegradable materials and their impact on the environment. In the literature section, biopolymers are first divided into groups according to biodegradability and sources. Finally, some industries in which biopolymers are used and the possibilities for removal are presented. At the end of the literature search, the work focused on the possible positive and negative impacts of biopolymers on the environment and life cycle assessment of these materials. Standards, certifications, and other environmental labels are also mentioned. In the practical part, an experiment was carried out with the decomposition of wet wipes under the conditions of a home compost. Wet wipes with a certificate of compostability in home compost and wet wipes without a certificate that were labelled as 100 % biodegradable by the manufacturer were examined. The goal was to verify the biodegradability of both products and compare their decomposition success rates. Detailed record
	Analýza biodegradability plastových materiálů v laboratorních a reálných podmínkách kompostování Zloch, Jan This thesis is focused on biodegradable or compostable plastics. Focuses on their pro-perties and uses. The work also clarifies the concept of biodegradable and compostable plastic. The work also describes the process of composting and concepts associated with it. Finally, there are several chapters devoted to the normative environment that relates to biodegradable plastics in the thesis. There are connected researches concerning the verification of the degree of degra-dation of plastics known as compostable, biodegradable and 100% compostable, in the last few chapters. There were conducted simultaneously two experiments of disintegration selected samples of biodegradable plastics. The tests of disintegration in the laboratory and in real conditions of composting were founded in March 2014 for a period of three months. There was founded a phytotoxicity test after the expiry of the time allotted in the laboratory. In a real conditions the study time was increased to 12 months. After evaluating and comparing the results of both tests disintegration may be allowed the use of biodegradable plastics in composting under controlled condi-tions. Conversely, in real conditions of home composting these plastics can not be re-commended, does not decompose. Detailed record
