Zanzibar City Plastic Waste Generation Stats & Recycling Infrastructure (2026)
A dense island economy where tourism-driven bottle consumption is high and off-island transport cost is the binding constraint on recovery.
Model updated 2026
Unmanaged polymer leakage
Modelled from an urban population of 710,000, 0.66 kg of municipal solid waste per person per day, a 12% plastic share and a 60% unmanaged share.
- Total plastic generated
- 56.2t / day
- Unmanaged plastic leakage
- 33.7t / day≈ 12,300 t per year
- Plastic share of waste stream
- 12%
- Unmanaged share of plastic
- 60%Uncollected, openly dumped or burned
| Polymer | Share of stream | Metric tons / day | Metric tons / year |
|---|---|---|---|
| PET (bottles, preforms) | 40% | 13.5 | 4,928 |
| HDPE (jerrycans, crates) | 20% | 6.7 | 2,446 |
| LDPE / film (bags, sachets) | 26% | 8.8 | 3,212 |
| Mixed / other polymers | 14% | 4.7 | 1,716 |
Collection workforce and hub targets
Recovery capacity is a function of people and aggregation points, not machinery. These figures size the human network a functioning system in this city would need.
- Informal waste pickers
- 620Estimated collectors already active in this city
- Collection hub target
- 28One community hub per ~25,357 residents
- Load per collector
- 54kg / dayIf the unmanaged stream were fully recovered by today's workforce
- Population served
- 0.71million
Proximity to processing and ocean-bound waterways
Transport distance decides whether recovered material is economic, and waterway distance decides how quickly uncollected material becomes marine debris.
| Measure | Reference point | Distance |
|---|---|---|
| Nearest recycling processing capacity | Dar es Salaam aggregators (via ferry) | 78 km |
| Nearest ocean-bound waterway (coast) | Zanzibar Channel | 1 km |
| Round-trip haul to processing | Per collection vehicle rotation | 156 km |
Methodology and data status
How these figures are produced
- Urban population from national statistics offices and UN-Habitat urban agglomeration estimates.
- Municipal solid waste per capita from World Bank What a Waste 2.0 income-band and country figures.
- Plastic share of the waste stream from national waste characterisation studies where available, otherwise the regional band (8–13%).
- Unmanaged share from UNEP and OECD mismanaged-waste ratios for the country's collection coverage.
- Polymer split from published characterisation of East and North African urban packaging streams.
- Hub targets model one community aggregation point per ~25,000 residents; collector counts follow published informal-sector surveys.
These are transparent desk estimates, not field measurements. AfriloopX is pre-pilot: any figure will be replaced with primary, weighbridge-verified data once collection operates.
Corporate teams pricing recovery in this city can cross-reference our plastic credit pricing reference for offset value per metric ton and reporting requirements.
