“…Clay minerals, with montmorillonite as the primary component, are commonly used as an effective leachate barrier in the landfills of toxic heavy metal ions and radionuclides (Rajesh and Viswanadham, 2011;Divya et al, 2012). Montmorillonite, an expandable 2:1 type phyllosilicate mineral, is the major clay component of sedimentary rock formations, weathered continental soils and aquatic sediments.…”

“…These liners are crucial as they act as a barrier preventing the leachate generated from the landfill to drain into the environment or groundwater aquifer [13,22]. Various materials used as leachate liners include natural clays, geomembranes (constructed from various plastic materials such as polyvinyl chloride (PVC) and high-density polyethene (HDPE)), geotextiles, geonet and geosynthetic clay liners [13,[22][23][24][25]. The lining system can be made from a single material such as clay or a combination of clay and other materials.…”

Landfilling of solid wastes has gained increasing acceptance due to the ease of disposal. However, such activity has consequences if the landfill site is not designed according to specification or does not have a leachate liner and collection system. Leachate possesses potential risk to surface and groundwater aquifer within the area surrounding the landfill site. The aim of this chapter is to assess the physicochemical parameters and heavy metal levels in leachate generated from a periurban landfill site situated in Thohoyandou, Limpopo Province, South Africa. Physicochemical parameters were measured onsite using standard methods, while heavy metals were analyzed with flame atomic absorption spectrometer (FAAS) after nitric acid digestion. pH, conductivity and turbidity values ranged from 6.97 to 7.68, 426 to 2288 μS/cm and 12.78 to 295.5 NTU, respectively. Most levels of the determined heavy metals exceeded the effluent discharge guideline limit of South African Department of Water Affairs. This could potentially spike their levels in surface and groundwater. Adequate measures should be put in place to manage the leachate generated from landfill sites.

“…Postoji veliki broj radova koji se bavi problematikom otpada [7] kao i pojedinim elementima tehnološkog projektovanja deponija kao što su: postupak deponovanja [8], izgradnja vodonepropusnih slojeva [9][10][11], upravljanje i tretman procednim vodama [12,13] i deponijskim gasom [14]. U domaćoj naučnoj literaturi postoje radovi iz oblasti upravljanja otpadom [15][16][17][18][19][20][21], ali je malo onih koji se bave samim procesom projektovanjem deponija [6,21].…”

IZVOD-Deponovanje otpada je element integrisanog upravljanja otpadom. Valjano izraĎeni projekti izgradnje i/ili zatvaranja deponije osiguravaju bezbedno odlaganje otpada, uz minimalne negativne uticaje na ţivotnu sredinu. U prvom delu rada izvršen je pregled i analiza deponija u Republici Srbiji. U drugom delu rada, u funkciji analize, opisani su značajni elementi tehnološkog projektovanja savremenih deponija koji uključuju: a) program deponovanja, b) obezbeĎivanje vodonepropusnosti dna i prekrivnog sloja, c) sakupljanje i tretman procednih voda i d) sakupljanje, tretman i iskorišćenje deponijskog gasa. U radu je konstatovano da postojeće, savremene deponije nisu u potpunosti projektovane u skladu sa propisima, te da je neophodna njihova rekonstrukcija. TakoĎe, postojeća smetlišta i divlje deponije neophodno je zatvoriti i sanirati. U ovom radu predstavljene su smernice za valjano tehnološko projektovanje deponija koje su u funkciji ispunjavanja zahteva i preporuka nacionalnih i evropskih propisa. Ključne reči: projektovanje deponije, program deponovanja, vodonepropusni sloj, procedne deponijske vode, deponijski gas ABSTRACT-Waste disposal is an important element of integrated waste management. In order to dispose of waste that is free of environmental risk, the proper design of landfills during their construction and/or closure is necessary. The first section of the paper presents the current state of landfills in Serbia, the second deals with problems in project design of landfills, especially in regard to their: a) program of waste disposal; b) impermeable layer; c) leaching collection and treatment; and d) gas collection and treatment. Analysis shows that many modern landfills in Serbia do not meet environmental protection requirements, therefore, they need reconstruction. All existing landfills owned by municipalities, as well as illegal dump sites, should be adequatelly closed. This paper presents the guidelines for successful landfill design which are to serve to meet the requirements and recommendations of Serbian and European regulations. Sound design of landfill technological elements should insure full sustainability of landfills in Serbia.
