This paper presents an analysis of the current practice in the field of municipal waste management in the Republic of Serbia. Data on generated, reused and disposed waste, collected by the Serbian Environmental Protection Agency, have been analyzed. The analysis showed that part of the generated waste is still not properly disposed of in sanitary landfills. Also, the paper presents municipal waste management methods that are most commonly used in the Republic of Serbia. From the data analyzed, it was concluded that the most commonly used method of waste management is landfill disposal. The aim of the paper is to present the improvements made so far in the field of municipal waste management practice through the Waste Management Strategy 2011 to 2019 with reference to the betterments and changes expected in the new Strategy in the coming period.

The purpose of this paper is to elaborate a plan for the leachate treatment at the “Zeljkovac” sanitary landfill in Leskovac city. Different processes occur over time  at the landfill. The processes of infiltration and transpiration occur continuously, distributing the humidity and affecting the water balance within the body of the landfill. The landfill body acts as a giant sponge, in which water moves, and from which water can be released - both into groundwater and into the atmosphere in the form of water vapour or as a filtrate at the bottom of the landfill. In this paper, particular attention is given to the kind of waterwhich is actually filtrate from a landfill, often called leachate. The efficiency of the most commonly used methods will be presented, depending on the most prevalent pollutants  in leachate. As there are many methods for treating this kind of wastewater, the reverse osmosis method will be presented as one of the most widely used . The technological process of a reverse osmosis plant will be described, as well as the result that shows the output quality of the leachate after the treatment process. The major finding of this paper reflects a clear justification for using this method to achieve the desired efficiency of leachate treatment.

Frankincense is an aromatic resin obtained from a tree of various species of the genus Boswellia, family Burseraceae. Boswellia serrata, which is characteristic for the Indian subcontinent and whose pharmacological effects have been proven in numerous studies, has the greatest medical importance. The aim of this paper is a detailed literature review of the chemical composition and biological activity of Indian frankincense resin isolates (B. serrata). In vitro studies and numerous clinical trials have shown promising beneficial effects in the treatment of inflammatory diseases, such as rheumatoid arthritis, ulcerative colitis, inflammatory bowel disease (ileitis), Crohn's disease and asthma, as well as in the reduction of peritumoral edema. The resin obtained from B. serrata which has both religious and medical significance is today widely used in the cosmetics industry due to its high content of essential oil.
