Vermicomposting of wine production waste
Clark, Oskar William ; Innemanová, Petra (advisor) ; Grasserová, Alena (referee)
Vermicomposting is a method of biological waste management, with the potential for valuable returns in the form of biofertilisers and savings of time and effort. These qualities make vermicomposting ideal for the processing of winery waste materials. Vermicomposting has advantages over traditional composting in terms of the speed of transformation of the input materiál, but also in terms of producing a safe fertiliser. Waste materials from the wine industry, which primarily include grape marc and winery wastewater, have several properties that can contribute to phytotoxic effects in soil. This thesis provides an overview of the management of waste materials from the wine industry, the differences between white and red wine production, and the suitability of vermicomposting for application in small- and large-scale winery waste management. The experimental part of this thesis examines the time requirement of vermicomposting to transform grape marc into a material that does not possess properties that inhibit plant growth. Experimental measurements of the relationship between vermicompost age and germination inhibition show that vermicomposting increases the pH of the substrate and stabilizes it over time. The experiment also showed that vermicompost has a statistically significant stimulatory...

Community vermicomposting of biodegradable municipal waste
Klubalová, Kateřina ; Innemanová, Petra (advisor) ; Hnátková, Tereza (referee)
The method of vermicomposting experiences a big boom nowadays. The people living in flats can process bio-waste, which they produce on their own. Therefore, the amount of biodegradable municipal waste contained in the dumped mixed municipal waste slightly reduces. In addition, people can benefit from high-quality products called vermicompost and its leachate called worm tea. In this work I summarize acquired knowledge about the vermicomposting focusing on kitchen waste, about conditions, which this method demands, about composition and the possibility of using the end products. Also, it is discussed which bio-waste is suitable for vermicomposting and what earthworm species can be used. The theoretical side of using worm tea in the hydroponic cultivation of plants is discussed. The toxicity of different concentrations of worm tea on a seeds of Sinapis Alba was tested in the experimental part. The concentration row 2,5; 5,0; 7,5; and 10,0 vol. % of four different samples of worm tea from different bio- waste was used. Distilled water was used as a control solution. The values of inhibition for each concentration of worm tea were calculated. Available literature recommends to dilute worm tea in ratio of 1:9 with water. However, the results showed that this dilution is already inhibitory for some...
