CONCLUSION<br />
From Table 5 and figure 1, a conclusion<br />
could be made about the presence of<br />
fine fraction below 0.038 mm (dust) in<br />
weight of 60.33%.<br />
Fine ash fractions can have a strong<br />
degradation effect on the environment,<br />
especially in the period of strong winds,<br />
which can lead to the major environmental<br />
problems, especially violations of public<br />
health, bearing in mind that this raw material<br />
categorized as the ha<strong>za</strong>rdous waste.<br />
This especially should be kept in mind<br />
when mechanized cleaning and transport<br />
of ash and slag from the cassettes in Medoševac<br />
to the landfill for permanent disposal<br />
of ash in the vicinity of nearby villages.<br />
In a view of its physical and chemical<br />
characteristics, the negative effects of ash<br />
on the environment are reflected through<br />
the pollution of air, surface and ground<br />
water, land, to the agricultural products,<br />
which directly threatens human health, in<br />
areas where those are. If it is possible to<br />
work on reducing the emergence due to<br />
minimize the occurrence of ash and slag.<br />
Regarding to the use of ash and slag in<br />
other industries, this type of materials can<br />
have significant use in the field of civil<br />
construction as a foundation for roads.<br />
The use of ash and slag like secondary<br />
materials could greatly reduce the amount<br />
of waste that is disposed in a landfill.<br />
