Effects of socio-economic status and daily variation on municipal solid waste composition: a preliminary analysis for sustainable planning and development in Aligarh City.

Abstract

In the context of developing countries such as India, with great differences in people's living standards and different communities, municipal solid waste (MSW) management is one of the most promising problems in front of municipal organizations. Unlike every city in India, Aligarh City also faces the same problem of municipal solid waste management. This problem not only affects the esthetic view but is also hazardous to people nearby health. Currently, solid waste collected is either dumped in landfill unscientifically or partially treated by A to Z waste management (limited) by composting. In the present study, an effort was made to know about the per capita waste generation and variations in the quantity of different components of the MSW in five different regions of the city with dissimilar living standards. Also, weekly variation was analyzed in the study. One-way ANOVA analysis using Statistical Package for the Social Sciences is performed to investigate the variations in the mean composition of different components. The per capita solid waste generation in Aligarh City was found to be 0.42 kg/person/day. From the analysis, we came to know that compostable component (35.4%) is the highest, then inert (24.6%), plastic (12.2%), paper (10%), textile (9.2%), and sand (8.6%). After analysis, the results can help sort out the problem of MSW management in the city by selecting appropriate units as per the composition of MSW.
