Dumpsite are often most neglected public infrastructure in all our cities today. Largely because it entails least development and operation cost required among all the types of solid waste disposal and thus it is the most prevalent type of disposal facility also in most countries today. With time as these landfill sites have grown in size and their environmental implications the closing and upgradation has emerged as an essential step in reducing serious public health impacts. Landfills by definition are sited designated for dumping rubbish, garbage, or other sorts of non-reducible solid waste. With the increasing amount of waste from our homes. offices, hospitals, markets and schools it is high time that this issue of waste dumping is handled in a scientific manner. However, despite many attempts to manage our wastes most communities and cities leave the landfill sites unattended which causes severe land pollution, degradation of ground water and an uncontrolled built up of all sorts of solid waste material. Since most of these wastes are non-biodegradable they heap in landfills and stay there for years. The scenario gets even worse when these landfill sites are used beyond their prescribed capacity causing unbearable stench and serious health risks which can be gastrointestinal, dermatological, respiratory and even genetic in nature.

There are many opportunities associated with the excavating of landfill sites. Many landfills were filled prior to large efforts in recycling and diversion tactics, which leads to many useful and valuable materials being hidden away from use. The prospect of reclaiming materials that were once buried relieves the need to use as much virgin materials for manufacturing and production processes. Organic materials that are recovered through landfill mining can be used to generate energy, or be utilized as cover material for the disposal facility. Through the removal of materials, more capacity can be generated within solid waste disposal systems, which can prolong the operating life of the facility, reduce the need to transport waste to other regions for disposal and ensure a longer period for which new landfills can be sited. Landfill mining is an option to recover valuable materials, storage capacity and generate energy but must be done where it is economically, socially and environmentally appropriate.

AbstractAppropriate landfill site selection for disposal of solid waste is a very complicated assignment, as it needs multicriteria analysis of various parameters. In this study, we have used QGIS for identification of alternative landfill site in Gurugram district, a satellite city of New Delhi. Various criteria are analysed for selecting the landfill sites. Weight and rank are assigned to the criterion such as road networks, presence of water bodies, residential locations, and depth of the underground water table by using the Analytic Hierarchy Process (AHP). Five possible landfill sites have been identified for solid waste disposal based upon the AHP method analysis and overlay analysis in GIS tool in Gurugram district. The methodology used in this paper is very efficient for performing multicriteria analysis and can be generalised for selecting landfill sites in other areas with similar demographics.
