What a scrapyard in Ghana can teach us about innovation | DK Osseo-Asare

In Agbogbloshie, a community in Accra, Ghana, people descend on a scrapyard to mine electronic waste for recyclable materials. Without formal training, these urban miners often teach themselves the workings of electronics by taking them apart and putting them together again. Designer DK Osseo-Asare wondered: What would happen if we connected these self-taught techies with students and young professionals in STEAM fields? The result: a growing maker community where people engage in peer-to-peer, hands-on education, motivated by what they want to create. Learn more about how this African makerspace is pioneering a grassroots circular economy.
