Staff of Wecyclers tries to sort recyclable goods collected from subscribers at Surulere district in Lagos on January 17, 2014. Nigeria's biggest city Lagos is home to some 20 million people and produces a staggering 10,000 tonnes of waste every day, a lot of which piles up on the busy streets or floats in open sewers. Currently, an estimated 40 percent of the megacity's waste is collected and taken to massive rubbish dumps, where scavengers pick through it for scrap and salvage to sell. But a new scheme is hoping to change people's attitude towards rubbish -- and their immediate environment -- by providing a material incentive to recycle plastic bottles, bags and tin cans.  "Wecyclers" is the brainchild of Bilikiss Adebiyi, who came up with the idea while studying in the United States for a masters in business administration.
