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
