1	Posouzení možnosti opětovného využití komunálních elektro-odpadů v obci Oralová, Petra January 2014 (has links) My graduation thesis was prepared on the theme Feasibility examination of reuse communal electro-waste in the town. My work is regarding problems with reuse of communal electro-waste in the Bělá pod Bezdězem. Within my work are described electro-waste groups and storage system. Followed part of communal electro-waste in the Bělá pod Bezdězem. On the base of analysis I described groups quantity of electro-waste and I discovered age and functional of electro-waste by the questionaire. I prefer way how we can separate functional electrical equipment flow from waste and how we can reuse functional electrical equipment in Bělá pod Bezdězem.
2	Analýza prvkového složení vybraného elektroodpadu Polická, Jana January 2016 (has links) This diploma thesis is focused on the issue of Analysis of the elemental composition of selected electrical waste (Waste Electrical and Electronic Equipment). The main goal is to determine amount of rare metals contained in central processing unit (CPU). The literature search was formed from available literature with the purpose to characterize the legislative framework for waste electrical and electronic equipment and the issue of collection of the selected e-waste in the European Union, particularly in the Czech Republic. In the practical part was analyzed selected samples of central processing units produced in 2000-2009. With the help of X-ray fluorescence spectrometry method was found to vary the amount of each element during the development of these units. Based on the results of completed survey we can conclude that the investigated samples con-tain economically usable elements. In the conclusion was evaluated the method which was used to determine the elemental composition and results was compared with other authors. This serves to see whether rare metals of processor that could be potentially economically exploited.
3	Materiálové toky a environmentální dopady malého elektroodpadu / Material Flows and Environmental Impacts of s-WEEE in the Czech Republic Polák, Miloš January 2015 (has links) This thesis is a comprehensive study describing and quantifying material flows of waste electric and electronic equipment (WEEE) in the Czech Republic; specifically the material flow of small waste electric and electronic equipment (s-WEEE) as well as representative substances. The studied material flows were estimated regarding aspects of the environmental impact. The End-of-Life mobile phone is seen as a typical representative of s-WEEE ; therefore material flows of mobile phones are described in this thesis as well. To put it in concrete figures, approximately 124 thousand tons of WEEE from households originated in the Czech Republic in 2010, where each inhabitant got rid off 4 pieces of WEEE in average. Further, total production calculating also consumer-like WEEE from companies and institutions was around 141 thousand tons in 2010. S-WEEE present around 15% from the total amount of WEEE originating in 2010; however it is more than 80% as regards the number of pieces. Despite of that fact the recycling potential of Au for instance is slightly higher by s-WEEE than by large WEEE (63kg/year compared to the 59kg/year respectively). As regards estimation of the total production of EoL mobile phones, around 45 thousand pieces originated in the Czech Republic between the years 1990-2000 and 6,5... Read more
