Abstract: Background: Management of solid waste in Khartoum State is the responsibility of municipal authorities; however insufficient data regarding solid waste constitute major challenges. A cross-sectional descriptive study was conducted in Al kalakla Administrative Unit to assess municipal solid waste management system. Materials and methods: According to methodology of the American Environmental Protection Agency, sixty households and 40 shops were sampled to examine the characteristics of the generated solid waste. Solid waste samples were collected for eight consecutive days from selected households and shops. The total numbers of samples weighed and sorted were 615, 654, 652 in Winter, Summer, and Autumn seasons respectively. Solid waste weighing, interviews, questionnaires and observations were used as data collection methods. Data were analyzed using Statistical Package for Social Science (SPSS) program version 16. Results: The average solid waste generation rate was 0.401 kg/p. d in residential area and 0.1 kg/ m2/day in Al lafa Market. There was strong significant difference in solid waste average per capita generation rate and solid waste density among seasons and residential sectors (P. value < 0.001). No significant differences in percentage of food remains, earth, plastic, papers, and tree leaves in solid waste among seasons (P. values = 0.17, 0.15, 0.09, 0.66, and 0.93 respectively). Most of housewives (98.3%) were aware of the solid waste hazards and accepted to segregate solid waste in their homes. Plastic bags and sackcloth were used as solid waste storage containers. Solid waste collection time and frequency were irregular and without voicing alarm. Occupational health services were not provided for solid waste workers. Tippers, trailers, roll off and compactors were being used to collect and transport solid waste. All collected solid waste was transported directly by collection vehicles to Taypa Al hassanab for controlled tipping. Conclusion: The average solid waste per capita generation rate in Al kalakla Administrative Unit is similar to the average per capita generation rate estimated by WHO, and completely different from the average estimated by Khartoum State Cleaning Corporation. Solid waste workers awareness towards solid waste risk was weak. Poor solid waste management practices were common in Al kalakla Administrative Unit, hence the collection efficiency was very low (52%) and all solid waste management activities didn’t meet national and international standards.
