Waste situation in urban slum areas and why this is important

Waste service do not reach slum areas

Slums are considered illegal and access is not always possible

Slum dwellers are not able to pay for the service but organise their own service

Slum Dwellers Recycle Waste for the city

Waste accumulates, burn, floods and slums are more affected

Slum areas are more vulnerable to disease

Slum street spaces are also spaces to live and do business
