Picking through a field of garbage, Nigerian artist Eugene Konboye hunts for particular type of trash: plastic flipflops that he turns into multi-coloured mosaic portraits of his community. Both an artist and environmentalist, Konboye says recycling flipflops targets one of the worst plastic polluting items in Nigeria, Africa’s most populous nation, with more than 210 million people and growing fast. Portraits on his studio walls slowly emerge from a pattern of the multi-coloured flip-flop pieces he arranges on backgrounds.
