GIS-Based Locational Analysis of Collection Bins in Municipal Solid Waste Management Systems

Article excerpt

Abstract: Solid waste management systems currently receive wide attention, from both economic and environmental planners, because of their complexity during coordination of various management strategies. The efficiency and cost effectiveness of route optimization and disposal site selection depend largely upon the appropriate placement of storage bins and their corresponding command area for waste contribution. The present paper illustrates a geographic information system (GIS) based algorithm for optimal location and number of storage bins, considering p-median constrained model, based on Indian guidelines for Municipal Solid Waste Rules. The algorithm also computes the contributing command area of solid waste to a particular bin, based on the shortest distance, with descending slope for ease in solid waste collection. Key words: municipal solid waste, bin location, command area, geographical information system (GIS).

Resume : Les systemes de gestion des dechets solides attirent presentement beaucoup l'attention des planificateurs economiques et environnementaux en raison de leur complexite durant la coordination de diverses strategies de gestion. L'efficacite et la rentabilite de l'optimization de route et la selection du site d'enfouissement dependent en grande partie de l'emplacement approprie des bacs de stockage et leur zone desservie correspondante pour la collecte de dechets. Le present article presente un algorithme base sur un systeme d'information geographique (SIG) utilise pour determiner l'emplacement et le nombre optimaux de bacs de stockage, compte tenu d'un modele p-median contraint, base sur les directives concernant la reglementation des dechets solides municipaux en Inde. L'algorithme calcule egalement la zone de collecte de dechets solides desservie par un bac de stockage particulier en se basant sur la plus courte distance, avec une pente descendante pour faciliter la collecte des dechets solides.

Mots-cles : dechets municipaux solides, emplacement des bacs, zone desservie, systeme d'information geographique.

Rapid increase in population and improvements in quality of life, especially in developing countries, have aggravated the problems of solid waste generation. It implies that the municipal authorities will require huge capital investments and operational strategies for collection, transportation, and disposal of solid waste. Delimiting factors such as limited financial resources have made it imperative to replace the existing ad hoc methods employed in solid waste management and planning (MacDonald 1996; Chang and Wang 1997). Most of the existing models for solid waste management are simple and seek optimum solutions, while only in a few models, trade-off between the economic and environmental objectives for integrated solid waste management system is considered (Chang et al. 1993; Nino and Baetz 1996; Harrison et al. 2001).

The activities associated with solid waste management can be classified into generation, storage, collection, processing, transportation, and disposal (Tchobanoglous et al. 1993). Fundamentally, the effectiveness of a solid waste management system depends mostly upon the proper location of bins, estimation of the waste generation and their on-site storage capacity. Amongst developing countries, the Indian scenario reveals that (Bhide and Sundaresan 2001) households are responsible for dumping waste into temporary storage bins while as per Municipal Solid Waste Rules (MSW 2000), municipal authorities in urban settlements are responsible for organizing house-to-house collection of wastes. The municipal authority in general selects corners of the roads for the placement of the bins, according to their convenience. The positions of the bins are changed frequently. Either due to remoteness or being extremely densely populated, some of the locations are not properly or adequately attended, resulting in more trips. …
