Biologicky rozložitelné polymery a jejich vliv na odpadové hospodářství
Zourková, Andrea
This diploma thesis is devoted to polymers, especially the biodegradable ones, and their possible impact on waste management. The theoretical part is focused on division and characteristics of particular biodegradable polymers, their life cycle or handling with them. Next chapter approaches the issue of certification and normative system and also polymer and packaging material applicable standards in the Czech Republic are given. At the end of the theoretical part the composting system is described. The practical part is divided into three parts in which the individual experiments are described. Plastic cups for hot beverages were used for research of biodegradability as they were guaranteed as fully biodegradable or 100% compostable.The first experiment is performed in laboratory conditions of composting, the second one tests biodegradation in electric composter and the third assesses biodegradability in gastro waste, laboratory conditions and electric composter.

Možnosti zpracování bioplastů
Dymchenko, Alan
This diploma thesis is focused on the issues relating to bioplastics and the possibilities of its processing. The first part of the diploma thesis deals with the issue of plastic packaging. Description of the history of plastic formation, plastics production and characteristics of bioplastics. It answers questions – what plastic is and why we need to degrade it. Classification of the most widespread in the use of bioplastics. Statistics on the production of bioplastics. Possibilities of processing of bioplastics. Factors that affect the decomposition of bioplastics. The second part of the diploma thesis is dedicated to laboratory tests, methodology of execution and analysis of laboratory results. It also describes the realization of self-attempted composting of bioplastics in domestic conditions.

Rozklad vybraných biologicky rozložitelných plastů v reálných podmínkách kompostování
Svobodová, Michaela
This diploma thesis is focused on problematics of biodegradable material, above all biodegradable of plastics and with relating normativ environment. Practical part is focused on monitoring biodegradable of plastics samples in real conditions of composting near Třebíč in Vícenicích u Náměště nad Oslavou, evaluation of gained result and conclusion with result that were achieved is also published thesis. The aim of this diploma thesis is to provide with all information regarding the manner of evaluating the decomposition of degradable polymeric materials and materiále marketed as degradable in real composting conditions.
