ABSTRACT
This paper will demonstrate the many benefits of cultivation of the biomass on the
sterile dump of the open mining pit and its use to produce electrical energy in the big boiler of the thermal power plants. The paper is elaborated in accordance with the priorities of the Romanian energy sector development with those of the EU energy policy, by increasing energy supply security by means of choosing a balanced fuel mixture, focusing on the use of lignite and renewable energy sources biomass providing the energy sector with competitiveness and supply security. The paper will presents the technical issues related to energy and the environment in that it takes into account all problems globally, namely air, water, soil and natural resources, mentioned both in EU legislation and therefore of Romania, in the field of wastes, pollutants from large combustion plants, climate change and energy strategy. In our researches we will demonstrate: how we can to obtain of two new products: biomass cultivated on sterile, ash and slag dumps and energy mix biomass: coal for burning in power plants and how we have a sustainable use of natural resources - biomass and fossil fuels to mitigate climate change and reduce greenhouse gas emissions. These products will have a positive impact on the competitiveness of the energy industry in Romania by developing and adopting renewable fuel combustion processes with coal.
