Kompostování bioplastů
 Kořínková, Aneta
The final work deals with research on the behaviour of various bioplastic materials placed in composting base under laboratory conditions and subsequent assessment of the phytotoxic effects of individual composts. Composting was carried out on the basis of modified standard ČSN EN 14045 and knowledge from standard ČSN EN 14046. The determination of chronic phytotoxic effects followed the modified standard ČSN EN 13432 and acute phytotoxicity was assessed using the Phytotoxkit test. Following completion of the composting process, decomposition was observed for the certified vegetable starch-based sample, two other samples without certification, but marked as 100% degradable, showed no evidence of decomposition. Various indicator organism growth inhibition values were observed, with chronic toxicity testing in the range of 3.4-20.9%, and phytotoxkit testing two of the samples showed a stimulating effect. Different bioplastic materials have achieved different results and represent a different level of potential environmental burden.
