    Opis:
    Evaluation of waste landfilling technologies performed has been presented with the technology quality assessment method. This method enables complex (technological, environmental, economic) comparisons of technological options including waste disposal involving emission (I) or utilization (II) of biogas, landfilling of treated waste from the mechanical-biological treatment (MBT) unit with emission of biogas (III) and treatment of waste in MBT unit plus option III (IV). Results of the technology quality calculation for options I–IV are 1971, 1709, 1170, 1748 points, respectively. If the technology quality of option I is 100%, utilization of biogas or introducing the MBT system improves technical quality by 11–13%.

    Opis:
    Mass balance of selected heavy metals (Cu, Cr, Pb, Hg, Zn, Cd) released from waste into leachate during 8 years of landfill exploitation has been calculated. The average release of all analyzed heavy metals did not exceed 1.7%. Heavy metals released in the largest quantities were Cr (0.025 –1.685%), Hg (0.033–1.540%) and Cd (0.082–0.701%). Release of Pb, Cu, Zn was 0.008–0.152%; 0.012–0.085% and 0.007–0.152%, respectively. Cr and Hg do not form an insoluble sulfide precipitate and that is why they are released in a larger amount. Cd and Pb concentrations are positively correlated with the amount of the atmospheric precipitation and the amount of leachates, which means that infiltrating rainfall can leach out these metals from waste. Favorable conditions for leaching of these metals are probably a result of their precipitation as carbonates. A strong correlation between Cu, Zn, and Cr indicates they do not precipitate as carbonates and further they can be subject to desorption processes. In the case of Cu, Zn, Cr and Hg, a positive correlation with the amount of deposited waste was also observed.

    Opis:
    Due to a very high percentage of organic matter in municipal solid waste (47.36%) and in total percentage of biodegradable matter (62.3%), organic waste disposed is the main source of methane emissions into the air in Albania. Capture, collection and utilization of landfill gas in an energy project leads to economic, health and environmental benefits. Energy recovery potential and methane emissions from Tirana landfill have been studied. This site is scheduled to be closed after 6 or 7 years. The evaluation has been done using LandGEM Colombia Model, version 1.0, as an international LFG Modeling. The model predicted the time of peak production in 2019, one year after assumed site closure. The total annual peak of predicted methane recovery from landfill within the study time frame was estimated to be 2950 m3/h and a maximum of power plant capacity 8.3 MW.

    Opis:
    An overview of municipal solid waste management (MSWM) in Poland has been presented. The processes of waste generation and composition have been described and a comprehensive review of MSWM in Poland has been provided, covering some of the important aspects of waste management, such as the current status of waste collection, transport and disposal in Poland. An additional aim of the present work was to identify the potential barriers and the factors affecting waste management as well as provide recommendations for system improvement in Poland and other similar developing countries. An analysis shows that the state of municipal solid waste (MSW) management in Poland is not yet as developed as in many other EU countries. Landfilling is still the predominant method used for the disposal of MSW. Composting and incineration are also used but refer only to a small percentage of the total. According to the latest data (31st December 2014), around 84% of MSW was collected and transported and that ca. 53% was disposed of in landfill, ca. 7% was incinerated at waste-to-energy plants, ca. 11% was treated at organic waste recovery plants and 23% was delivered to sorting. The average generation rate of MSW was 293 kg/capita/year. Generally, recycling in Poland is on the increase, especially concerning easily collectable and recyclable materials such as paper, plastics, glass and metals. Around 37% of MSW collected selectively is recycled.

    Opis:
    The paper aims to provide insight into data on leachate migration, composition, and migration time and to improve the engineered barrier system (EBS) importance through different pollutant concentrations in the landfill at the base of the unsaturated zone and off-site, for the real-case scenario with composite liners (EBS) and the worst-case scenario with no liners (NO EBS) using the Land Sim software for 30, 100, 1000 and 20 000 years in 1000 iterations. Also, the paper aims to analyze the leachate leakage through the waste for different migration times and different internal layers to create a qualitative and quantitative basis for assessing leachate’s impact on the environment. The results obtained by modeling the parameters of the real case at the Gigoš landfill showed that the leachate leakage amount is about 340 times lower when EBS is present and concentrations of nitrogen, chlorides, arsenic, lead, cyanides, and mercury in the worst-case scenario (NO EBS) exceed the permitted limits according to the laws of the Republic of Serbia.

    Opis:
    The technology of municipal solid waste treatment in a landfill bioreactor is based on a system of controlled, enhanced fermentation of organic waste, which occurs in a heap having status of bioreactor. The enhancement of biogas production is done by leachate recirculation. In a landfill bioreactor, located in Kosiny Bartosowe, Poland, with capacity of 70 000 Mg of municipal solid waste, the research aiming on the determination of the influence of leachate recirculation on biogas generation was done. Experiments were done in two periods: just one month after bioreactor sealing with hydraulic loading rate (HLR) of 2 mm/d, and one year after bioreactor sealing with HLR of 3 mm/d. Doubling of biogas production from about 100 to 200 m3/h and the increase of methane content from 60 to 65% has been determined when 2 mm/d of HLR of leachate recirculation was applied. The implementation of HLR on the level 3 mm/d increased biogas production from 148 to 270 m3/d, and methane content from 62 to 64%. Leachate recirculation improved thermal conditions in bioreactor to typical meso-philic values.

    Opis:
    One of the most difficult tasks encountered when implementing waste management practices in Turkey involves the selection of the most suitable area for a landfill. The Geographic Information System (GIS) which possesses the ability to imitate and process economic and environmental constraints, presents itself as a useful and effective decision support tool. This study will utilize the GIS to determine feasible alternative landfill areas on the European side of Istanbul, which has a high density population, showing that accurate selection results can be achieved at lower cost.
