The object of research in this scientific paper is the treatment of waste generated by paper production in industrial landfills. In the part of the paper production process, i.e. in its subsystem for wastewater treatment, a significant amount of solid waste is generated, which ends up in industrial landfills. The reason for the impossibility of returning to the production process lies in the fact that the sludge contains larger amounts of moisture and present chemical components that are isolated in the paper production process or during wastewater treatment. In the experimental part of the paper, a “trial plot” was selected on which seedlings of the paulownia elongate plant were planted in the waste sludge. The process of plant growth was monitored for two years and bioremediation, i.e. transfer of elements from sediments to plants, was analysed by modern instrumental methods. Based on the results obtained by research, it can be said with certainty that Paulownia elongate can be used in bioremediation of areas where these sediments are deposited.

Interest in paulownia got its momentum around the world. With its fast-growing nature and large leaf surfaces this species can absorb significant amounts of sulfur dioxide and dust particles. The cities of Tuzla and Lukavac, as most other Bosnian-Herzegovinian towns, have a number of geo-ecological problems, and the most pronounced one is negative anthropopressing on the atmospheric complex and pedospheric cover. This area, especially during the winter period, has a disrupted air quality where the greatest polluters are individual heating places, transport, industry and energy sector. The pedologic cover of the wider area of Tuzla and Lukavac has suffered significant changes and is largely devastated. The processes of destruction of soils lead to complete destruction or formation of a new land with modified characteristics. High rainfall is a major cause of destabilization of slopes, but also is the negative anthropogenic activity in the area. Landslides have caused significant material damages, particularly in the residential structures of slope zones of the mentioned cities and suburban areas. This paper presents the basic biological characteristics of woody species paulownia elongata, and the possibility of planting it in areas that are now unused so to improve the quality of air, as well as on surfaces that are threatened by landslides.

Lukavac, as many other Bosnian and Herzegovinian industrial cities, especially in the winter period, has deteriorated air quality and the greatest polluters are industry, individual heating and transportation. Considering that Lukavac is situated in the valley in which numerous industrial facilities are installed, in the periods of unfavorable weather conditions the town and its surroundings are naturally predisposed for additional air pollution. In this paper we analyze the possibility to form bioparks, which would have positive impacts on the ecological and economic conditions in Lukavac and similar environments. To establish the bioparks, the degraded and abandoned land surfaces, caused by soil erosion or the surface exploitation of mineral resources, could be used. These are located at numerous locations and cover large areas, both in Lukavac and in other industrial areas in Bosnia and Herzegovina. This paper presents the basic biological characteristics of paulownia and possibilities of planting this tree in areas that are now unused, in the space which is characterized by extreme pollution of atmospheric complex. The selected method is bioremediation, and in this case it is the planting of biological material or woody plant species Paulownija elongata. In this way the degraded surfaces would get the function of biological parks, that is, they would become "oxygen producer" surfaces, and absorbers of CO2 which is emitted from industrial plants. This species has rapid growth and development of biomass, so the bioparks could be used to serve as the surfaces for alternative fuel with minimal amounts of sulfur, and also as eco - educational parks.

Power plants, such as coal boilers, emit flue gases containing solid particles and gases resulting from the combustion of coal. One of the most dangerous pollutants emitted is certainly sulfur dioxide. Therefore, the reduction of emissions of sulfur dioxide has become a legal obligation. So far the most successful method of reducing the content of sulfur dioxide in the combustion products leaving the environment is injecting limestone or lime in combustion and to provide conditions for the reaction between the injected lime and sulfur dioxide from combustion products still in the combustion chamber. This method has been successfully used in thermal power plants to coal. This paper deals with the possibility of introducing the process of dry flue gas desulphurization created during coal combustion in boilers of smaller.
