The landfill of waste from nickel production is situated to the south of Sereď in Slovak Republic. The landfill area covers around 50 ha. Volume is in present day 5.5 - 6.5 mil. [t] and in 1993 it was about 9 mil.[t]. The land-fill was formed during 30 years of manufacturing process, which was stopped due to the economic and ecologi-cal reasons in 1993. The pollution of base rocks, underground waters, soils and air pollution was noticed during production in the Nickel smelting plant and continues up to the present days. In this paper we focused on the current structure on the landfill of waste from nickel production and its impact on the environment. Physical and chemical properties of the waste are responsible for the creation of a specific ecosystem, not peculiar to the natural landscape, which negatively affects the quality of the environment. It is proposed to reduce waste using microwave vitrification method, although it is very expensive, but the most effective, because procedure in converting waste glass provides high chemical stability and water resistance.
