摘要

This paper focuses on one of the major environmental concerns of urban centres of developing countries, i.e. the remediation or closure of waste dumps. Data was collected and analysed for 62 waste dumps sites from 26 cities of India. Eight remediation/closure alternatives were considered for containment of the dumps. A multi-criteria analysis (MCA) approach was adopted to select the most appropriate alternatives for different sites. The proposed method uses the concept of modified and normalised scores to relatively rank the alternatives. The method was applied to 11 dumps with varying site conditions and observed to be sensitive to changes in conditions and perform satisfactorily in identifying different options for distinctly different sites. The decision-making method performs well with the available limited information on the waste dumps rather than elaborate geo-environmental parameters.
