Hodnocení rozkladu různých typů degradovatelných plastů v laboratorních podmínkách kompostování

The thesis aims to determine the actual degradability or biodegradability of selected samples of plastic bags in a controlled composting environment as well as the impact of biodegradable plastics on the final quality of compost. The theoretical part of the work describes the characteristics of synthetic polymers. The following chapter is devoted to biodegradable plastics and outlines their types, certification options as well as the normative support in the Czech Republic. In addition, it briefly characterizes the composting process itself and defines phytotoxicity. The practical part evaluates the experiment carried out on samples of plastic bags during the composting process and summarises the result of compost quality obtained by phytotoxicity testing
