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.
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.
Hodnocení rozkladu různých typů rozložitelných plastů v laboratorních podmínkách kompostování
Dostálová, Dagmar
This Master's thesis deals with a topic "Evaluation of various types of degradable plastics degradation in the laboratory conditions of composting". First part is devoted to the description of biodegradable plastics, its use and criteria relating to biopolymerms. There is also described the process of composting and composting technology possiblities. The main part of this work carries out an experiment according to standardized methodology, which deals with the degradability of the materials in laboratory conditions. These materials are commonly available on the Czech and Polish markets. At the end of the work there are discussed results in comparation with the results of other similar experiments.
