In 2002, Idaho buried nearly 300 tons of crushed waste glass beneath Highway 75

Idaho's innovative approach has seen nearly 300 tonnes of waste glass repurposed as road foundation material, addressing both engineering challenges and local waste management issues. The crushed glass cullet, strategically laid beneath a highway section, has proven to be an effective solution, showcasing the potential of recycling in constructing sustainable infrastructure. This project represents a significant advancement in civil engineering practices through resource optimization.
