The study evaluates municipal solid waste generation, composition, and management in the Douala municipality of Cameroon at landfill level. Load count analysis was used for the systematic assessment of the flows and stocks of materials within the landfill in space and time. Descriptive and inferential statistics methods were used to draw conclusions. The results show that, on average, municipal solid waste composition in the municipality has been changing over time. On average 490194580 Kg of wastes are generated per month, giving a per capita generation rate of 0.54 ± 0.071 kg person-1month-1. While inert (7.4±0.8), metal (2.6 ± 0.8), glass (3.5% ± 1.3), and paper (14.5% ± 0.9) wastes (2.0% ± 0.1) had higher proportions in the dry season, plastic (16.1% ± 2.6), organic (49.8.3% ± 3.1) and special wastes (2.0% ± 0.1) had higher proportions in the rainy season. However, at α = 0.05, all waste categories resulted in P > α, with extreme critical values for the test statistic t, suggesting that waste composition do not significantly differ from season to season. Similar results were observed for the mean generation rates across the different districts.Forecasting generation rates could be important for proper planning of operations related to solid waste management.
