  Background and Objectives: Population growth, urban development, and increased human activities will bring various outcomes, including the production and accumulation of waste, followed by environmental pollution. In developing countries, construction waste accounts for a large proportion of municipal waste, which in addition to the high cost of disposal, also has adverse effects on the environment. Because construction debris takes up a lot of space due to its bulk, disposing of it in landfills reduces the useful life of these areas and it is necessary to find a new place to bury construction debris. Method: Searching for a new landfill is a complex and time consuming process and requires a capable and efficient system, as using GIS and combining different layers of information and considering environmental, social and economic criteria, the most suitable landfill can be found. Located a building. In the present study, 16 criteria (slope, land use, residential, commercial and industrial centers, villages, roads (including 3 layers of highways, main roads and side roads), water (including 6 layers of wells, springs, aqueducts, Rivers, dams and waterways), antiquities, airport runways and mines) are involved in the location process, so that privacy and distance maps are prepared first ,then, in order to achieve more reliability, scoring the classes or parameter intervals was done in three ways. Criteria were weighted using Expert Choice software and hierarchical analysis (AHP). Findings: The results of the three types of scoring to multi-criteria analysis showed that there were significant differences in the results of different methods of scoring. Discussion and Conclusions: The results of combining 16 parameters involved in site selection in software Arc GIS9.3 showed that the appropriate zones for construction and demolition wastes buried in Hamadan, often are located in a 90-degree slice.

  Abstract Background and Objective: Nowadays, landfill method is used as the last strategy in the integrated solid waste management hierarchy. It is more common and has lower costs than other sanitary disposal methods. Selecting the suitable landfill site can prevent the inappropriate ecological and socio-economical effects. Landfill site selection requires the analysis of spatial data, regulations and accepted criteria. The main objective of this study is to determine the suitable common municipal solid waste landfill site for Khomeynishahr and its 6 adjacent cities. For this purpose, the multi criteria evaluation method, GIS and Analytic Hierarchy Process (AHP) were used to evaluate the suitability of appropriate landfill site by emphasizing on regional vision. Method: Different information layers related to the maps of the study area were provided and superposed using both the Boolean and fuzzy methods (classification of suitable areas in the valued range of 0 to 255) in the GIS environment. The AHP was used for weighing the information layers. Findings: After the necessary analysis, the proposed suitable landfill sites with an area of less than 1% were defined in 5 regions and in central parts of the study area. Conclusion: The results obtained from this study can be used as the first priority to help the decision makers in suitable landfill site selection.   Manuscript profile

  Background and Objective: Landfill leachate has been identified as a potential source of ground and surface waters contamination due to the generation of leachate. Further, landfill leachate may percolate through soils and cause the large pollution of streams, creeks and water. Hence, the aim of this study is to evaluate the performance of a laboratory-scale ABR in different COD concentrations and hydraulic retention time for COD removal. Method: In this research, an anaerobic baffle reactor (ABR) was used for biological landfill leachate treatment. The ABR was 10 cm wide, 60 cm long, and 10 cm depth and was constructed from Perspex with an effective volume of 6 L. The ABR was seeded with anaerobically digested sewage sludge taken from an anaerobic digester of a wastewater treatment plant in Qaemshahr city. Landfill leachate used in this study was collected from a landfill leachate waste municipal site located in Kiasar, Sari. The experiments used in this study were chemical oxygen demand (COD), pH, suspended solids (SS) and alkalinity. Findings: The anaerobic baffle reactor (ABR) has been have an appropriate performance for COD removal of landfill leachate. Also, the results showed that this reactor presented an acceptable capability of pH control and acidogenic microorganism separation from others. On the other hands, the results demonstrated that an alkalinity remained at the desirable level in the reactor and it is not necessary to add chemical materials to control it. Moreover, the suspended solids were significantly removed in this reactor. Discussion and Conclusion: The obtained results indicated that the highest COD removal (86%) was achieved at the HRT of 2 days where the COD concentration of 2700 mg/L was reduced to 380 mg/L. Furthermore, the system performance at lower hydraulic retention time was decreased. At the COD concentration of 2700 mg/L, 70% decrement of the reactor efficiency was observed by decreasing hydraulic retention time to 12 hr. Manuscript profile

  Nowadays, the population increase in line with the technology advances has improved life and thus has caused a rapid increase in consumption and eventually led to a huge increase of wastes. So that, the production of these materials has created a huge environmental disaster in human societies in recent years which is considered as one of the major challenges facing humanity. In recent years, especial equipment is used to collect, manage and transfer gas in landfills. Collecting landfill gas (biogas) have different benefits in environmental fields, economic and , the most important, energy. The biogas produced by urban Landfill has a high proportion of volatile organic methane that damages the ozone layer. Landfill gases are produced through a collection of biochemical reactions on biodegradable organic matter present in the waste in anaerobic conditions. These gases include methane, carbon dioxide hydrogen, hydrogen sulfide, volatile organic compounds and so on. Assessment and prediction of production rates and factors affecting gas emissions from landfill are critical for landfill designing and successful utilization of the gases as an energy source. Thus, the present paper has studied these matters.   Manuscript profile

  In today's growing world that explosive population growth it has an endemic growth of residual and its specific contamination, the environmentalists' minds are concerned about the extent to which the material can endanger the environment, water, soil and air. The unhealthy disposal of solid waste on different organisms at different concentrations and pollution intensities will produce different effects. The purpose of this study, environmental assessment Yazd solid waste landfill for this purpose, environmental sampling of the environmental elements of the current landfill site and determine the composition of municipal solid waste was done. The results of the well water analysis showed a slightly higher concentration of some of the investigated elements in the lower reaches of the burial site than the World Health Organization's (2008) standard for drinking. Soil analysis results showed a slight increase in the concentration of some elements in and near the landfill (in the direction of the slope of the layers), compared to the Canadian standard (2004) for agriculture. The analysis of the well water in the control and sample samples was lower (far from the burial site), and the concentration of the elements was close to the normal range. In relation to the analysis of leachate, the parameters are not consistent with the irrigation and agricultural standards of the Water Pollution Control Agency (2011). Finally, it can be said that the results of the analyzes did not show the widespread and critical effects of burial on the environment, especially the urban environment. Manuscript profile
