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...
