Life cycle assessment of municipal waste
Vlach, Josef ; Slavík, Jan (referee) ; Jícha, Jaroslav (advisor)
The aim of this study is to present methodology life cycle (LCA) and Life Cycle Assessment of disposal the municipal solid waste chain. There is described the procedure of generation of the LCA studies according to the standards ČSN EN ISO 14 040 and ČSN EN ISO 14 044 in the first and second part. In the third part of this diploma there are described LCA analyses that have already been created. The software GEMIS (Global Emission Model for Integrated System) is described in the fourth part. The computer model GEMIS has been used as a calculation tool in this study. The fifth part of this study includes waste management and different kinds of disposal municipal solid waste. In this part is describe basic data about landfilling and incieration. There is shown LCA analysis of disposal municipial solid waste in the sixth part. Data processing was carried out by means of the software GEMIS 4.3. The results were interpreted for incineration and landfilling. Finally there is mentioned results for 1 TJ different elektrical energize to.

The current position of LCA in the air market
Hašková, Denisa ; Vaško, Martin (advisor) ; Voříšková, Barbora (referee)
The aim of the thesis is to analyze the current position of LCA in the global aviation market with a focus on low-fares in the Europe.The thesis defines traffic, especially air transport and low-cost carriers. The current position is shown for example by their share in the air market from a global perspective and also from the perspective of the European region.

Greenhouse gasses emission load within animal production
LAŠTŮVKOVÁ, Jana
This thesis deals with a quantity of CO2 emissions produced during breeding of pigs. Two systems of farming (conventional and organic) were compared between each other. With help of questionnaire survey the data were obtained ? they were needed for a calculation of CO2 emissions in software program SIMA PRO which calculates emissions produced in agricultural phase: the breeding of animal from its birth to the end of fattening and converts them into CO2 equivalent. The aim of this work was to find out, which system of farming produces more CO2 emissions.

Greenhouse gasses emission load during vegetable growing
KRATOCHVÍLOVÁ, Pavla
This thesis is focused on a survey whether the production of greenhouse gases by cultivation of vegetable, concretely garlic, is higher in a conventional way of cultivation or in an organic way of cultivation of garlic (from view of the environment). The study is composed on the base of all system processes which are used during cultivation of garlic. It was clear from collection of input data (which were obtained by questionnaire or telephone survey) that main processes for calculation would be mainly agricultural processes. An emission load of CO2 equivalent to a kilogram of individual product was calculated from obtained data and information from a database Ecoinvent. The purpose of this work is making information about possibility of choice of food and its influence on the environment available to people. It should help them to choose which food they want to eat. The conclusion of this thesis is the result which shows that organic cultivation of garlic is more sparing to the environment because it produces less emission than conventional agriculture.

Environmental aspects of eggs production from point of view of greenhouse gasses emissions
KALKUŠ, Václav
The aim of the study is to compare poultry farming focused on either conventional or organic egg production. Detailed information has been gathered in particular organizations by the means of questionnaires and provided technical literature. We have concentrated on the monitoring of the emission impact on the environment, caused especially by feed material consumption, electricity consumption and farm dung management. Based on the gathered data the emission burden was calculated by the means of Ecoinvent database using CO2 equivalent. We have compared the individual systems of management and evaluated greenhouse gasses production. The main target of the thesis was to find out whether the production of organic eggs has smaller impact on the environment than the conventional one.

Hodnocení celkového ekologického dopadu využití jednotlivých alternativních zdrojů v ČR
Asociace pro využití obnovitelných zdrojů energie, Praha ; CityPlan spol. s r.o., Praha
Cílem práce je zevrubné posouzení alternativních zdrojů energie nejen s ohledem na jejich ekologické dopady, ale také na jejich dopady na celou společnost. Projekt obsahuje: Posouzení ekologického dopadu využití jednotlivých alternativních zdrojů v ČR pomocí bilančního lineárního modelu GEMIS; Vzorce chování člověka – nároky na energii současné a budoucí společnosti, pokud bude probíhat vývoj jako „business as usual“; adaptace člověka na proměnné životní podmínky; Zhodnocení potřeby energie pro neplýtvavý, leč kvalitní život; cesty ke snížení energetické náročnosti, potenciál úspor (proces dematerializace); Politická strategie a priority – jak dosáhnout udržitelné hladiny spotřeby energie v ČR v dlouhodobém měřítku; Synergie a antagonismy jednotlivých obnovitelných a alternativních zdrojů energie - dopady ve vztahu k udržitelnému rozvoji; Globální rozdělení energetických zdrojů a nejlepší cesta pro ČR v získávání energie ve střednědobém měřítku; Energetické a jiné krize (přizpůsobení energetického systému krizím; krize, přežití a zaměstnanost; adaptace člověka na krize).
