DETERMINANTS OF DOMESTIC WASTE SEGREGATION IN RURAL SECTOR OF SRI LANKA: AN EMPIRICAL ANALYSIS

Abstract

Domestic waste in the rural sector in Sri Lanka is a significant problem since there is no proper mechanism to collect waste. Hence, domestic waste is disposed of improperly without being segregated. Therefore, this study aims to determine the factors that affect domestic waste segregation in the rural sector. Primary data collected from 500 households in four rural villages of Hakmana divisional secretariat division in Matara district were used to analyze the objective. Factor analysis and the Probit regression model were used to determine the factors that affect waste segregation. The results revealed that only 11 percent of households properly dispose of waste after segregation, while other households dispose of waste improperly, resulting in numerous adverse consequences. Factor analysis identified five factors: awareness, behaviour and attitudes, moral norms and responsibilities, situational factors, and trust in local authorities. The Probit model indicated that age, number of family members, and situational factors have a negative effect on waste segregation. In contrast, income, female decision-makers, education, land size, awareness, attitudes, norms and responsibilities, and trust in local authorities positively impact waste segregation. Provision of necessary facilities and intensive implementation of waste collection methods, awareness programmes and enhancing the knowledge on consequences and benefits of waste segregation are recommended policies that can be implemented. Implementation of recycling industries in the rural sector is also recommended.
