ABSTRACT The appropriate site selection for waste disposal is one of the major problems in waste management. Also, many environmental, economical, and political considerations must be adhered to. In this study, landfill site selection is performed using the Geographic Information System (GIS), the Analytical Hierarchy Process (AHP), and the remote sensing methods for the Senirkent-Uluborlu Basin. The basin is located in the Eğirdir Lake catchment area, which is one of the most important fresh water in Turkey. So, waste management must be regulated in the basin. For this aim, ten different criteria (lithology, surface water, aquifer, groundwater depth, land use, lineaments, aspect, elevation, slope, and distance to roads) are examined in relation to landfill site selection. Each criterion was identified and weighted using AHP. Then, each criterion is mapped using the GIS technique, and a suitability map is prepared by overlay analyses. The results indicate that 96.3% of the area in the basin is unsuitable; 1.6%, moderately suitable; and 2.1%, most suitable. Finally, suitable regions in the basin are determined for solid waste landfill disposal and checked in the field. The selected and investigated regions are considered to be suitable for the landfill.

    ABSTRACT: The purpose of developing a mining project is to meet the demand for metals and minerals resources to improve the quality of life of the society. This is obviously connected with the generation of a considerable volume of waste that could create environmental impact and health risks. However, one of the most important strategies in waste management is to select the optimum waste dump site. To face with this problem, managers go in search of the techniques that not only can take into account the technical and economical factors but also consider environmental aspects to get a better perspective on the problem under consideration. According to a large number of criteria influence the process of the waste dump site selection, this problem is a multicriteria decision making (MCDM) issue. One of the most standard techniques used for formulation of a sophisticated problem under different criteria that are often in conflicting with each other, is Additive Ratio Assessment (ARAS). In this paper, the ARAS based group decision making (GARAS) for evaluating and prioritizing the possible sites under partial or incomplete information is proposed. The proposed model contains three main stages. In the first stage, the main and sub-criteria are identified. In the next stage, the outputs of the questionnaires filled by evaluator team based on linguistic values are aggregated into the final decision matrix. Then, fuzzy GARAS is used to evaluate the aggregated values for assessment of alternatives and selection of best one. In the last stages, a sensitivity analysis is conducted to determine how the importance weights influence the process of the decision making. To demonstrate the potential application of the proposed model, a real case study is illustrated. The strength of the proposed model is its effectiveness and capability to produce proper solutions under the inherent uncertainty involved in the process of modeling a real-life problem.

    ABSTRACT: Kolkata is one of the four major metropolitan cities in India and the capital city of the state of West Bengal. With an area of 187.33 km2 and a population of about 10 million (including a floating population of about 6 million), the city generates about 3500 Metric Ton (MT) of solid waste per day. Currently, Kolkata Municipal Corporation (KMC) disposes its waste at Dhapa (21.47 ha), where the disposal rate exceeds 3000 MT/day, and at Garden Reach (3.52 ha), where the disposal rate is 100 MT/day. Considering the exhaustion of Dhapa land space, city planners are urgently searching for an alternate disposal ground. National Environmental Engineering Research Institute (NEERI), under the sponsorship of Central Pollution Control Board (CPCB), has brought out literature developing the site selection criteria for municipal solid waste disposal ground to suit Indian conditions. The developed criteria encompass environmental conditions, accessibility, geological and hydrogeological conditions, and ecological and societal effects. This paper attempts to locate the most suitable site for disposal of KMC area solid waste using the multicriterion decision analysis as stipulated in CPCB 2003 guidelines and the overlay analysis of geographic information system (GIS).Implications:The paper is based on landfill site selection for dumping of solid waste generated within Kolkata Municipal Corporation (KMC) area. The methodology uses GIS/remote sensing, Site Sensitivity Index (an offshoot of pairwise comparison technique developed in CPCB 2003 guidelines, Government of India), and the Delphi technique. Dhapa landfill site, where solid waste of KMC area is currently being disposed, is exhausted; the authors of this article thus found it relevant to carry out a research on the selection of an alternative landfill site. The study undertaken was comprehensive, yet presented in a lucid way so that policymakers will find easy to comprehend.

    ABSTRACT: Since hot melts are "No-Water" compounds, they take very less time to attain peak bonding strength. These compounds penetrate into the bonding surfaces prior to cooling. So if the surface is roughened before applying hot melt, it is better able to adhere itself to the surface. Hot melts should be used with polystyrene or polyethylene substrates. The vinyl acrylate is one of the best adhesives for polyurethane. Also in case of polystyrene, vinyl acrylate leads to the formation of a metallic bond with the young's modulus in the range of GPa (quite abnormal for a non metallic substance like polystyrene). To test the strength of the joints, UTM was used. It revealed the data concerning the bonding strength of various adhesives. X-ray diffraction and FTIR revealed the structures of these adhesives.
