Fractionation of biodegradable municipal waste to produce biogas and solid biofuels production
VELEK, Jindřich
The theses deals with the use of biologically degradable waste which needs to be processed and utilized in maximum amount. It is highly desirable to apply new and well-known technologies to treat such waste efficiently and not to dispose it in landfills unreasonably, as is the case at present. The paper describes landfilling, composting, anearobic digestion, mechanical and biological treatment of waste as well as various stages of the lability concerning fractions of organic compounds. The stages of the lability concerning fractions of organic compounds are in particular determining the best utilization of such biologically degradable waste in each technology. It is advisable in this case to apply the STEAM EXPOLOSTION or IFBB technology for treatment of biologically degradable waste. These technologies were used in the proposal for the utility model which specifies how to produce biogas or solid biofuel from waste.
Current technologies and landfilling of waste and its prospects in the Czech Republic
VELEK, Jindřich
This bachelor thesis deals with waste management in the Czech Republic, especially landfilling. Different types of landfills, their technical aspects and methods of depositing waste are described. The thesis also describes the main legislation concerning waste management in the Czech Republic and tries to point out material and energetic use of waste before landfilling. Recycling is considered to be important because it decreases the amount of waste stored in landfills. Composting and anaerobic digestion are the other methods of disposal. The thesis also describes the possibilities of usage of the landfill gasses with the help of cogeneration units. The thesis refers to current level of waste landfilling in the Czech Republic and predicts the future development.
