In collaboration with the Danish Road Authorities, Saferoad Traffic successfully tested road signs made from industrial hemp as an alternative to traditional aluminum plates. Launched in 2024, these bio-based signs are produced using non-active hemp fibers that are fully compostable and designed to meet a variety of regulatory and performance requirements.
The initiative is rooted in circular economy thinking. Unlike aluminum, which requires high energy input and complex recycling processes, hemp plates can return to nature without leaving a lasting footprint. The materials align with cradle-to-cradle principles, offering a new approach to product life cycles in infrastructure.
“This development shows how even the most familiar parts of our roads can be reimagined,” a spokesperson for Saferoad Traffic said. “We’re proud to offer a solution that reduces material impact while still meeting the safety and functional standards our customers depend on. It’s a step forward in how we think about road equipment and sustainability.” says INSERT NAME
While steel poles are still used for mounting—ensuring compliance with safety standards—the shift to hemp-based signage significantly reduces material-related emissions and reliance on non-renewable resources. By early 2025, more than 7,500 of these signs had been sold for use in various public and private road projects across Denmark, indicating strong market interest and adoption.
