Project Background: Lot 1: Feasibility Study on Circular Organic Waste Management in Dar es Salaam ,Tanzania. Dar es Salaam generates approximately 1.36 million tons of municipal solid waste (MSW) per year, equivalent to roughly 3,700 tons per day.1 Organic waste constitutes the dominant share of the municipal waste stream, accounting for an estimated 50-60%2, originating primarily from households, markets, institutions, and food-related enterprises.This organic fraction presents significant management challenges due to its high moisture content and contamination levels. Existing waste composition data are outdated, limiting informed technology selection and appropriate facility sizing. Seasonal rainfall further affects both waste characteristics and access to disposal sites, while the accumulation of waste in drainage channels exacerbates flooding and related public health risks.
