Solid waste management is a vital area that needs to be addressed as it leads to a sustainable environment and welfare of the public. Unfortunately, in developing nations, improper solid waste management leads to the pollution of the environment and this affects people’s health. The challenges and the improvement measures for solid waste vary for each country, depending on various factors, like topography, demography, and people’s awareness. This study is based on the quantitative sustainability assessment of solid waste management in Sana’a, Yemen. The questionnaire survey has gone through a pilot study for a reliability test with 17 respondents. After the pilot study, the questionnaire survey was distributed randomly to the people living in Sana’a City. This study involved 106 respondents in total. The purpose of the pilot study was to check the questionnaire’s reliability based on the Cronbach’s Alpha value for both key challenges and the improvement measures of solid waste management. The Cronbach’s Alpha value estimates of key challenges and improvement measures are 0.924 and 0.876, respectively. This study found that the key challenges of sustainable solid waste management (SSWM) in Sana’a City are lack of awareness and glitch in recycling as the most critical aspects. Consequently, for this reason, it leads to a lack of encouragement for recycling, with the valuation of the mean being 4.10. Hence, effective and efficient improvement measures are to be practised in overcoming these issues. This paper incorporates the challenges and the improvement measures, which can be implemented to harmonise and sustain the environment and public welfare.
