Komparativní analýza vybraných systémů nakládání s komunálním odpadem ve Spojených státech amerických

This thesis concerns a comparison of two currently the most frequently occuring recycling waste systems in the United States of America -- Single stream and Dual stream recycling systems and an assessment of feasible utilization of Single stream system in the Czech Republic. The comparison is performed from several aspects: investment costs, operating costs, costs of the processors of secondary raw materials, costs of environmental pollution caused by CO2, SO2 and NOx, capacity utilization and citizens participation in the system, focusing on a single commodity; paper and cardboard waste. As according to realized studies the systems represent different load for individual entities in the economy cost-benefit method is used for the comparison. Using this method, four collection areas and the most important beneficiaries (municipal entity, secondary raw materials processors, landfill and residents) involved in the system are analyzed in the state of Pennsylvania. None of the existing studies did not take into account costs and benefits of more than one entity so far. In the Czech Republic no such studies have been realized, therefore this issue has become the subject of this thesis. In term of costs and benefits for the municipal entity the results of realized studies coincide in results of this thesis, i.e. Dual stream recycling system is more suitable for small collection areas. However from the point of view of all the major beneficiaries results of this thesis vastly differ. Based on this analysis it can be concluded that any of the above mentioned systems is not suitable for small communities, regarding the fact the values for the Single stream system are less negative. Application of Single stream system in the Czech Republic, namely in Prague, with all its limitations (we assume costs derived from the U.S. market) comes more favorable than the currently implemented system.
