Lignite is the basic raw material used by thermal power plants in Serbia to
produce electricity. In the process of burning coal, ash appears as a secondary product for
17% (data from the Nikola Tesla Power Plant). Fly ash, which is an ultrafine ash content,
causes air, water, and soil pollution, and is the main cause of a significant increase in the
number of various diseases among the surrounding population. A chemical analysis of fly
ash samples from the Nikola Tesla thermal power plant in Obrenovac was performed, and
results were obtained that inevitably require a reaction in terms of eliminating the components found in this product. The presence of heavy metals was established: Zn, Cr, Cd, Sr, Pb, Co
and Ni. Despite the fact that these elements are difficult to dissolve in water, they led to
serious environmental pollution, which eventually led to very serious health complications,
primarily in the population living directly next to the thermal power plant. The air very e...asily
disperses this fly ash, and besides it pollutes water and soil, not only in the surroundings
but also on a larger surface of the land, the particles carried by the wind spread to areas
that are more distant. The toxicity of these heavy metals is particularly dangerous due to
their cumulative deposition in the human body, which is the last in the food chain, and is
in direct danger due to the presence of fly ash from the air, water and soil, through cultivated
agricultural products. This is a very complex problem, which is the subject of research
and finding solutions in many countries. At the same time, elemental sulfur appears as a
secondary product of oil refining. By applying sulfur in the process of homogenization and
agglomeration of ash in amounts from 15% to 22%, coating and increase of ultrafine ash
particles <63мm in size is achieved and their presence is reduced from 17.5% to 1%. The
product obtained in this way can easily and without additional investment be disposed
of in landfills without the possibility of polluting the environment. This would prevent and
significantly reduce environmental pollution, as well as further illness of the population due
to the influence of the presence of fly ash. It would also solve the problem of sulfur disposal
as a secondary product of oil refineries. The resulting agglomerate of ash and sulfur could
be further used in construction.
