Conceptos bricks, founded by Oscar Mendes and Isabel Christina Gomez in 2010 in Colombia, has built over 300 classrooms in the country. In 2019, UNICEF approached them to expand to Ivory Coast, where over a million children lack access to education due to a shortage of classrooms. Each classroom, accommodating up to 80 children, takes a month to build, with the government estimating a need for 30,000 more. Despite having enough plastic waste in Abidjan to build 45 classrooms daily, the challenge lies in collecting, sorting, and transforming the plastic. Conceptos aims to involve local communities in the process, having already transformed 3,000 metric tons of plastic in Ivory Coast. The initiative not only addresses the plastic waste issue but also positively impacts the environment and people's lives, providing a sense of ownership and empowerment.
