The present Master's thesis seeks to present the landfill Ostri vrh in Logatec, its current function and
its possibilities after closing it. The landfill does not have a valid environmental usage permision
anymore therefore it is in the closing process. The landfill was established in year 1977 when the issue
of waste management was not yet so familiar and developed. Situation in the field of waste
management has improved significantly since then, mainly due to the implementation of appropriate
environmental policies. Today much more waste is reused or recycled and this leads to empty landfills
across the country. The same situation is in the landfill Ostri vrh. As a starting point basic concepts
and definitions in the field of waste management and the regulatory framework that applies to the
scope of the European Union and Slovenia is presented. It is followed by an insight into the impact of
the landfill on the environment and its status quo. Second part of the thesis is focused into presenting
conceptual solution for the landfill closing and the possibility of technological processes for
purification of leachate. One of the possible solutions is complete closure of the landfill as defined by
the Regulation on the waste landfills. That would mean construction of the sealed cover in order to
isolate it from its surroundings. System of pumps would create a closed loop of the leachate, so we
would not need an independent wastewater treatment plant. In the event that leachate would not be
returned to the landfill, it would be necessary to clean it with means of membrane technology, physicchemical
or biological processes. Furthermoew, the thesis also presents a method of forced ventilation
and energy use of landfill waste with a plasma reactor. Thus, on the basis of both a study of the
literature and analysis of the empirical data collected through the research results show that currently
complete closure is best and money affordable solution.
