One of the greatest challenges and sources of opportunity for modern engineers is thinking up ways to repurpose the waste material that pervades our planet. Many organizations are already finding clever ways to tackle this issue. For example, every year the PBS show Design Squad holds a “Trash to Treasure” competition, which challenges students to design something useful produced from waste materials.
