September 15th of each year is dedicated to World Clean Up Day.  On this occasion, Sandra Idossou, the young Beninese eco-activist, and her partners proceed to the collection of plastic waste in the city of Cotonou. It is through the Eco-running initiative that it implements with the fitness club “Flex Fitness”, as well as several partners. This initiative had its third edition in September 2018. It is a project that mobilizes every year more than a hundred participants cross the main roads of the city of Cotonou to rid them of plastic waste such as plastic bag, plastic bottles of water and others. In September 2018, a total of one tonne and 264 kilograms of plastic bags were collected.
