The bachelor’s thesis deals with the topic of waste gasification. The first part includes the definition of waste with the focus on municipal solid waste, its evaluation as fuel on the basis of its contents and properties, in this case the heating value. Eventually the waste is compared with other normally used solid fuels. The second part presents and describes the thermal processes applied to waste-to-energy technologies, where the gasification is explained in more detail, its final products, the content of contaminants in these products and their removal. The next part deals with technologies used for waste gasification. The last part deals with the issue of waste gasification in the Czech republic
