Rubbish littering the streets is a problem all around the world but collecting it can also be a vital source of income. Two projects, thousands of miles apart, are trying to clean up the streets and make life better for rubbish collectors at the same time. In Nigeria, a start-up called Wecyclers is helping people profit from their waste, with the help of bicycles, tricycles and an incentives system. In Brazil, a phone app called Cataki is helping connect litter pickers and people with rubbish in an attempt to professionalise these informal recyclers.
