Vliv vybraných faktorů na kolonizaci biologicky rozložitelných plastů mikroorganismy
 Novotná, Markéta
This diploma thesis deals with the degradation of biologically degradable plastics. It focuses on the intensity of their degradation under the conditions of composting and on the influence of various factors on the colonization of biodegradable plastics by microorganisms. In the introduction of the theoretical part the key concepts of the field of biodegradable plastics are defined. The difference between plastics that are actually biodegradable and that are subject to only partial degradation is specified. Further the description of the process of biodegradation of polymers and the definition of biodegradability and compostability of polymer sis noted. At the end of theoretical part, the composting proces is described, with the enumeration of the phases and factors that influence the process. The practical part is devoted to the examination of the degradation of biologically degradable plastics in composting conditions both under a laboratory and under operating conditions. Laboratory experiment is complemented by the study of the influence of various factors on the process of biodegradation and on the intensity of colonization of biodegradable plastics by microorganisms.
