- Abstract
The paper presents the management of material waste flows in Southern Serbia through the analysis of techno-economic and ecological status. Waste generated during the construction and reconstruction of facilities is planned, whereby the place and method of its disposal must be provided. The construction waste life cycle analysis method uses recorded data on stored waste at a landfill in South Serbia, as well as the number and locations of wild landfills in 2016. For the selected time period, data on the total cumulative amount of waste, as well as the partial cumulative amounts of concrete, brick and asphalt that can be reused or recycled, are presented. The amount of wood waste could not be estimated because the separation of such waste is done at the source and has not been recorded. According to the statistical reports from 2015, there are 184 registered, unregulated and mixed landfills, while going forwards 43 landfills were cleaned, with 141 still remaining unclaimed. In Donja Jajna landfill, owned by the public utility company “Komunalac” from Leskovac city, there is a solid waste dump. On average, about 10 trucks arrive at the dump in Donja Jajna, which amounts to 50m3 of construction waste, 20m3 (i.e. 40%) of which consists of concrete. The calculated amount of construction waste annually amounts to 18250m3 of construction waste, of which the concrete itself is 7300m3. Considering that the landfill is 10 years old, it is estimated that it currently obtains 73000m3 of concrete. The current state and perspectives of the management of construction waste in the Southern Serbia region are assessed in this paper. The previous practice in the management of construction waste indicates that there is only one active landfill of construction waste that operates without any engineering principles. Estimations of material flows are done on a database obtained from a public utility company. Analysis of flows for wild landfills is excluded from this research since the share of construction waste there is negligible. Currently no further treatment of the waste is performed at the observed landfill, so concrete as well as other construction waste, is permanently disposed of by burial. Considering the landfill and the estimation of the amount of permanent inflow of new waste, it can be concluded that the reuse and recycling of concrete, bricks and asphalt in construction units would be a cost-effective investment with stationary recycling equipment.
