Environmental risks Assessment arising from the implementation and operation of biogas-stations

Environmental pollution, natural resources consumption and global climate change have been threats for mankind since 21 century. In order to antedate environmental pollution in many countries of the world including The Czech Republic we use legislative tool as a process of influence of the environment EIA. Substitution of non-renewable energy sources for renewable ones may retard global climate change markedly. This thesis deals with analysis of specific biogas plants located in Moravian-Silesian region in relation to the environment and population. It means that it deals with biomass utilization as a renewable source of energy. Within EIA process, it assesses the unity rate between prediction, said in documentation, and the real state after implementation. As far as the population perspective is concerned, poeple assess great strength, weaknesses, opportunities and threats. Results of the research showed different perceptions of biogas before and after project implementation. The risk of discomfort housing (smell, increased traffic congestion, noise) threatens residents in older facilities where an EIA was not yet part of the legislation. The results also showed compliance with the information provided in the EIA documentation in relation to the population and the environment, and the state after realizing the plan of a biogas plant. The thesis brings us new information within post-project analysis, it shows us the importance of EIA process and publicity involvement into this process. Defining the specific effects of biogas plants by mutual cooperation between the investor and the public authorities can be achieved some functioning device with regard to population and environmental components
