Salubata manufactures modular shoes from recycled plastics and algal bloom. As a pair of shoes requires about a kilogram of plastic waste for its production, this initiative significantly contributes to the reduction of the vast amounts of plastic waste generated. One of ‘Africa’s 100 Most Promising Start-Ups’, the company, based in Lagos, Nigeria, aims to produce 5,000,000 shoes per year by 2023. In addition to contributing to waste reduction, 5 per cent of profits are donated to help children confronted with malnutrition.
