Household practices and determinants of solid waste segregation in Addis Ababa city, Ethiopia

Abstract Solid waste segregation plays a critical role in effective waste management; however, the practice remains at a low level in developing countries like Ethiopia. Despite the persistent nature of the problem, there are limited studies to date that can provide sufficient empirical evidence to support appropriate efforts by policy makers and practitioners, particularly in the context of the developing world. Therefore, the main objective of this study was to analyze household practices and determinants of solid waste segregation in the urban areas of Addis Ababa, the capital city of Ethiopia. To achieve this objective, data were generated through a household survey, focus group discussions, key informant interviews, and field observations. The collected quantitative data were cleaned, encoded, and statistically analyzed using descriptive statistics in SPSS, while thematic analysis was undertaken to evaluate and describe the qualitative data. The data analysis revealed that only 21.3% of respondents reported frequent solid waste segregation, while about half (45.5%) segregated solid waste rarely. Conversely, a considerable proportion (28.7%) of the respondents reported not segregating solid waste, and the remaining 4.5% of respondents were unsure about the practice. This implies that only one-fifth of the total sampled respondents actually implement solid waste segregation practices at the household level. The chi-square test showed that respondents’ awareness/training (P = 0.000) and use of social organizations to discuss waste management (P = 0.001) are significantly associated with the practice of solid waste segregation. This highlights the need to focus on awareness-raising efforts among the general public in order to improve the knowledge, attitudes, and behaviors of individual households and residents toward solid waste segregation practices. Additionally, enabling policies, sufficient infrastructure, and incentive mechanisms can also help enhance wider adoption of the practices.
