Summary/Abstract: In this paper are presented some issues regarding the natural resources and as well as some possibilities of saving them. Also, the paper presents aspects concerning the reuse of wastes from energy industry (ash and slag), from extractive industry (drilling sludge) and from metallurgy industry (metallurgical slag) in order to achieve new building materials with big added value and low energy consumption. Due to fizical and chemical properties these wastes can replace natural resourses such as: the ash and slag from power plant can replace the sand, drilling sludge can replace the clay and metallurgical slag can replace the special hydraulic blinders (chalk).On the other hand, in our country the biomass was not used in power plant boiller to electrical energy production so far. From this perspective, there is the possibility to plant the biomass on the large areas of steril dumps or even on the surface of the ash deposits. In this way should be solved some environmental issues (for example: reduction of the impact of ash deposits on the environment by the mitigation of blowing ash, the reduction of the erosion of the soil in the case of dump, the neutral CO2 balances of biomass) and also quantities of lignit should be saved by the replacement with the biomass. An unexplored field so far is represented by the heavy and rare metals recovery from the thermo power plant ash. We consider that is the new concept that must be explored in the future in order to assure the necessary of such materials essentialy for the high tech industry.
