Abstract

PurposeThe purpose of this paper is to determine the socio-economic factors related to household solid waste generation and its type based on field surveys in South Delhi Municipal Corporation area in Delhi, India.Design/methodology/approachThis paper develops a framework to systematically identify the socio-economic factors related to household waste generation and its type. The framework uses both primary and secondary data.

Multinomial logistic models are developed. The models are analyzed using the SPSS software version 22.0.FindingsThe study reports that socio-economic parameters like monthly income of the family, number of family members, occupation, education are statistically significant predictors. Further, detailed disaggregated models reveal more insights that are not apparent otherwise, such as the number of females can also be a significant factor for a targeted socio-economic group.Practical implicationsThe results can help in forecasting the resource requirement for waste collection, establishment of processing facilities and other policy planning measures for effective waste management, as summarized in the discussion.Originality/valueA systematic process to determine resource requirement according to socio-economic (and consequently spatial) group constitute an important component of the novelty of this study. Further, it provides new insights on the role of various socio-economic factors in determining the quantity and composition of household waste, e.g. quantity and type of waste can also be affected by male and female qualification within a socio-economic category.
