In order to line up with the European requirements regarding environmental and energy efficiency as a result of Romania's accession to the European Union, it is required the technological rehabilitation of coal plants, namely the fulfilment of installations for flue gas desulphurization and the review of the existing disposal, transport and storage systems of products resulting from the combustion of coal in power units' boilers. For further proper operation, Electrocentrale Deva (Mintia Thermal Power Plant) is required to make investments to reduce the environmental impact of ash and slag deposits, this being possible through the implementation of new technologies, such as dense slurry technology. This paper shows the concerns of Electrocentrale Deva on environmental impact in terms of air, water and soil, by implementing a new technology for disposal and transport of waste coming from the combustion of fossil fuels. Changing this technology will provide the reduction of "excess water" volume, seeking to reduce the content of the hydro-mixture: 1 part slag - ash - 10 parts water, used in the old technology (1:10) at a ratio of 1:1.1 using the dense slurry technology. By implementing this technology and building a new storage, starting with 01.01.2016, it shall be observed the current European legislation (Directive 1999/31/EC on waste discharge and storage) which will make possible the continuous operation of Mintia thermal power plant.
