The thesis is evaluating the influence of frequency balance of containers for sorted for sorted waste for the intensity of sorting in two locations in České Budějovice. The influence was examined using three independent methods (monitoring the filling of containers ? by a balancing caluclation ? by a questionnaire) At the assessment of the impact of collection frequency to the selection account was taken of the following criteria: full containers at the time of collection, walking distance of population to the containers for sorted waste, type of buildings in the monitored area, sorted waste containers capacity, the amount of sorted waste, population per one collection point, etc. The results showed that the level of sorting of mixed waste in České Budějovice is not at good level. Collection frequency of sorted waste is sufficient and is not limiting to the intensity of sorting. For the efficiency of collection there is proposed tu optimize the placement od containers for sorted waste, to consider a different system off collection for residential areas, to introdukce a special containers for sorting of PET bottles and to raise form filling of paper containers by englightenment.

Planer finns till att bygga ett mikronät på Hemsön, i Härnösand. Denna studie syftar till att utreda möjligheter till detta och om möjligt identifiera var kostnadsbesparingar kan göras inför byggnationen och implementeringen av denna energigemenskap. Mikronätet kommer innefatta 18 tomter varvid sommarstugor förväntas byggas och enligt kontrakt även ska inkludera en produktionsanläggning för egenproducerad el, vilka förväntas bli solceller. En utredning har även gjorts för att finna svar på om energilagring via elfordon kan utnyttjas i stället för ett batterilager. Studien har funnit att denna typ av energilagring har potential att eliminera behovet av inköpt el under sommarmånader då solel produceras. Vidare har studien tydliggjort att implementering av detta mikronät ej tillåter en högre total produktion än 44,1 kW, vilket är betydligt lägre än först var väntat. Studiens resultat visar på att kabelskåpets impedans bör reduceras om högre produktion är önskat. Detta kräver vidare dialog med elnätsföretaget och en fortsatt utredning för detta är rekommenderat i framtiden. / Plans have arisen to build a micro grid in Hemsön, Härnösand. The purpose of this study is to evaluate possibilities for solutions and identify ways to save on costs during the building and implementation of the micro grid. The grid will contain 18 building plots where vacation homes may be built, which by contract shall include energy production assumingly solar panels. An investigation has also been conducted regarding if electric vehicles can be used for energy storage instead of batteries. During the study it has been found that energy storage through electric vehicles has the potential to eliminate the need to buy electricity during the summer months when solar power is produced. Furthermore, the study has shown that the maximum total production of solar power for the micro grid is 44,1 kW which is less than first expected. It has been found that the impedance needs to be reduced if a higher production is wanted. To resolute this, a dialogue needs to be held with the power supplier which is recommended going forward.
