LCA application to Russian Conditions

The environmental impact assessment existing in the Russian Federation at the present moment cannot provide potential scenarios of consequences for the environment from examined processes, since its goal is to calculate the money equivalent of emissions to the environment. Also, it cannot help the environmental specialist to choose the most environmentally sustainable scenario or process, proceeding from the whole life cycle of the object, because it is usually performed only for the use phase of an object. This study also aims to show possibilities for applying LCA methodology, as accepted in the ISO standards series 14040, and as applied to Russian conditions. The main purpose was to investigate a possibility of using the existing environmental impact assessment as the inventory stage in the LCA. As the minor goal, normalisation and weighting factor data for the Russian Federation were calculated on the basis of energy consumption extrapolation. In this paper, the environmental impacts are associated with a sewage wastewater facility. The inventory analysis is performed with data obtained from the MosvodokanalNIIproject (Moscow Research Institute for sewage wastewater treatment facilities) and supplemented with the SimaPro 5.0 database (the Netherlands). The environmental impact categories included and discussed in this study are eutrophication, global warming, landfill, acidification, ozone layer depletion and photochemical ozone creation. This study was performed for several design alternatives or scenarios of the wastewater facility. According to the LCA performed in this study, the most environmentally sustainable scenario is that which has the most effective and complicated treatment of sewage water and sludge.
