ANALYSIS OF USE OF PAULOWNIA ELONGATA AS AN ALTERNATIVE FUEL IN THE CEMENT INDUSTRY TO REDUCE EMISSIONS OF POLLUTANTS
Today there is a growing research activity in order to investigate the possibility of using various waste or alternative materials in the cement and other industries. In this paper the possibility of using wood paulownia (lat. Paulownia elongata) as a completely new type of alternative fuel has been analyzed. Its applicability in cement industry in...

THE POSSIBILITY OF BIODIESEL PRODUCTION UNDER LABORATORY CONDITIONS
Because of the oil shortage and the growing increasing environmental burdens-emission from motor vehicles, the idea of the biofuels application has been actualized. The European Union directive 2003/30/EC obliged Member States that until 31 December 2005, they must provide at least 2% share of biofuels and other renewable fuels in the total amount ...

THE WATER FILTRATION TECHNOLOGY SELECTION FOR WELL „KRUŠČICA“
Water that is commonly used for drinking is groundwater, that appears on the surface of the Earth's crust as sources of different types and capacities, and in most cases that water is chemical, physical and bacteriological acceptable and suitable for use. In some cases, there is some blurring of water, that is the result of heavy rainfall or some h...

RECYCLING REFRACTORY WASTE FROM THE IRON AND STEEL INDUSTRY
Refractory materials are an important part of industrial furnaces and metallurgical aggregates. With time and use, the wear out of refractory materials ocures and their replacement becomes necessary. Part of refractory material, which is removed after the demolition of industrial furnaces and metallurgical unit refractory linings, represents refrac...

FLOTATION WASTE AS A SECONDARY RAW MATERIAL – FROM ENVIRONMENTAL PROBLEM TO ECOLOGICAL SOLUTION
Flotation tailings represent the sources of pollution due to degradation of the areas in the vicinity of industrial facilities, raising dust that pollutes the air and penetration of contaminated water into water courses. Flotation tailings Bor, which was the subject of research in this paper, contains copper and is, therefore, a pote...

COMPARATIVE PREDICTION OF THERMODYNAMIC PROPERTIES FOR Ga-Sn-Zn SYSTEM
The results of the comparative prediction of thermodynamic properties for Ga-Zn-Sn system are presented in this paper. Two thermodynamic predicting models were used for the calculation – one symmetrical (Muggianu), one assymetrical (Toop) model and general solution model. The calculations were done for different sections in exa...
