The consequence of increase in the exploitation capacity of copper ore at the open pit "Veliki Krivelj" is the expansion of the Saraka landfill. The result of landfill expansion is a degradation of the surrounding land. The impact on the quality of the environment as a result of these works is greatly impaired. In order to protect it, it is necessary to intervene in such a way that the neglected areas of the Saraka landfill are recultivated as soon as possible.
