Why Isn't the U.S. Using Recycled Glass for Paving Roads?
Despite its abundance and environmental benefits, recycled glass remains vastly underutilized in U.S. road construction. While other nations like Europe and Australia have embraced glassphalt—a mixture of recycled glass and asphalt—as a sustainable road material, the U.S. lags behind due to several factors:
- Cost: Glassphalt is more expensive than traditional asphalt due to the cost of collecting, processing, and transporting the recycled glass.
- Technical challenges: Glassphalt requires specialized equipment and techniques to ensure durability and performance.
- Contractors' resistance: Traditional contractors may be reluctant to adopt new technologies like glassphalt due to concerns about cost and liability.
- Lack of policy support: The U.S. lacks comprehensive policies that incentivize the use of recycled materials in road construction.
By overcoming these challenges, the U.S. could reap significant benefits from using recycled glass for paving roads. Glassphalt has been shown to increase road durability, reduce noise pollution, and improve traction. Additionally, it diverts glass from landfills, conserving resources and reducing waste.
